As for the temperature sensor 4, a preferable mode is: the temperature sensor 4 selects a water temperature sensor with the precision of 0.1 ℃ to acquire more accurate water temperature information, so that the control unit 3 can conveniently control the water temperature sensor.
In fig. 1, a cooling pipeline 5 of a hollow tubular structure is represented by a double solid line, communication connection is represented by a dotted line, the cooling pipeline 5 is divided into different branches through a valve 6, each branch is used for cooling a device to be cooled, and the temperature sensors 4 on the branches are in communication connection with the control unit 3. In addition, although the cooling pipeline 5 of the device to be cooled is disposed around the device to be cooled, since the manner of disposing the cooling pipeline 5 is well known to those skilled in the art, the connection of the cooling pipeline 5 to the device to be cooled in fig. 1 is only a simplified schematic diagram, and in practical applications, a suitable method for disposing the cooling pipeline 5 at the device to be cooled should be selected according to needs. Meanwhile, fig. 1 only shows the case that the cooling pipeline 5 is divided into two branches by the valve 6, but it is easy to know that the arrangement manner of more branches is the same, and the description is omitted here.
It should be noted that, in the present embodiment, the kind of the cooling liquid in the cooling pipeline 5 is not limited, and can be freely selected according to actual needs, but for the sake of cost and the like, the cooling liquid is generally water, and in the following description, water is also taken as an example for description. In addition, the water inlet shown in fig. 1 may be connected to a water source or supply, the water outlet may be connected to the outside or a water storage, and a preferred embodiment is: the water outlet and the water inlet are connected with the same water tank. Thus, the water circulation in the cooling pipeline 5 is realized, and the water resource is saved.
Meanwhile, the temperature reduction device based on the vacuum sublimation purification equipment shown in fig. 1 is only a simplest implementation form, and the temperature reduction and circulation of water are realized through one refrigerator 1 and one water pump 2, but actually, one refrigerator 1 and a plurality of water pumps 2 can be configured, and each water pump 2 controls the flow rate of water in different branches; one water pump 2 and a plurality of refrigerators 1 can be configured, and each refrigerator 1 controls the temperature of water in different branches; a plurality of water pumps 2 and a plurality of refrigerators 1 can be arranged, and the flow rate and the temperature of each branch of water are respectively controlled by a control unit 3, so that a better cooling effect is obtained.

The application provides a heat sink based on vacuum sublimation purification equipment is through in each branch road with valve 6 divided, be provided with respectively with the 3 communication connection's of the control unit temperature sensor 4, make the control unit 3 can acquire the temperature in the cooling pipeline 5 of treating the cooling equipment cooling for the difference, change refrigerator 1 and water pump 2's power according to actual need, and then change the temperature and the velocity of flow of cooling pipeline 5 water-logging, when realizing better cooling effect, still avoid only setting up the electric energy waste that lower temperature leads to for refrigerator 1, and because cooling pipeline 5 low temperature crosses lowly, and then make vapor condense in outer wall department, make sublimation vacuum purification equipment surrounding environment humidity increase, influence the problem of product purity. In addition, this application still will treat cooling pipeline 5 of cooling device cooling for the difference through valve 6 and separate, through the degree of opening and shutting of control flap 6, realizes the cooling more to the ization to reach better cooling effect.
Because in vacuum sublimation purification equipment, the cooling demand of different equipment of waiting to cool down is not necessarily the same, so, as shown in fig. 2, this embodiment provides a preferred embodiment, and water pump 2 is connected with cooling pipeline 5 specifically and is:
each cooling pipeline 5 for cooling different equipment to be cooled is connected with a different water pump 2.
The power of different water pumps 2 is determined by the demand of the equipment to be cooled on the branch where the water pumps 2 are located, the power of the water pumps 2 can be set in advance, and can also be controlled by the control unit 3, and this embodiment is not limited to this, but generally speaking, in order to adapt to more complicated cooling demand, an optimal solution is:
the water pump 2 is a variable frequency water pump, is connected with the control unit 3, and is used for controlling the flow rate of water in the cooling pipeline 5 according to the flow rate control signal sent by the control unit 3.
Under the certain condition of water temperature in cooling pipeline 5, if the cooling demand needs faster cooling for waiting to cool down the equipment at present, then control unit 3 sends control signal to the frequency conversion water pump, improves the power of frequency conversion water pump to improve the water velocity in the current cooling pipeline 5, equally, control unit 3 also can reduce according to cooling demand control frequency conversion water pump power and practice thrift power consumption.
This embodiment sets up different water pumps 2 respectively through waiting the cooling pipeline 5 department at cooling device place with the difference to realize the differentiation control of the 5 interior water flow rates of cooling pipeline of different branch roads, and then satisfy the different cooling demands of waiting cooling device of difference. And the frequency conversion water pump more can adapt to different cooling demands for the water pump 2 of decide power, in addition, because the frequency conversion water pump can also reduce its output when the cooling demand is not high to reach the purpose of practicing thrift the electric energy.
Therefore, in the above embodiment, the different branch of the cooling pipeline 5 is provided with the different water pumps 2 to realize the differentiated control of the flow rate, and the flow rate of the water in the cooling pipeline 5 is also an important index affecting the cooling capacity, so as shown in fig. 2, this embodiment further provides a preferred embodiment, and the cooling device of the vacuum sublimation purification apparatus further includes: a flow meter 7;
each cooling pipeline 5 for cooling different equipment to be cooled is internally provided with a flowmeter 7, and the flowmeters 7 are connected with the control unit 3 and used for returning the current flow speed information of the cooling pipelines 5.
Although the present embodiment is not limited to the type, model, specification, etc. of the flow meter, a preferred solution for selecting the flow meter is provided: the flowmeter 7 with the maximum measuring range not less than 10 meters per second is selected.
Each flow meter 7 of the present embodiment is disposed in the cooling line 5 of different branches, but the further disposition is not limited, and generally, the flow meter 7 is disposed at the inner wall of the cooling line 5. But because the cooling pipeline 5 of same branch road probably because factors such as pipeline bending lead to the pipeline in everywhere the velocity of flow of water not identical, so for the more accurate measurement for the velocity of flow of the water of waiting to cool down equipment cooling, this embodiment still provides a preferred scheme and is: the flowmeter 7 is arranged on the inner wall of the cooling pipeline 5 surrounding the equipment to be cooled.
The control unit 3 is in communication connection with each flow meter 7, and is configured to obtain flow rate information of each branch returned by each flow meter 7, and further adjust the cooling temperature of the refrigerator 1 according to the cooling requirement determined by the information returned by the temperature sensor 4. Or the output power of the variable frequency water pump in the above embodiment is adjusted to achieve the purpose of adjusting the flow rate of the water in the cooling pipeline 5.
In addition, it should be noted that fig. 2 shows a schematic structural diagram of a temperature reduction device based on a vacuum sublimation purification apparatus, but the embodiment is not limited to the relative relationship among the arrangement positions of the refrigerator 1, the water pump 2, the temperature sensor 4 and the flow meter 7 shown in fig. 2, and fig. 2 is only a reference case. Generally, however, the refrigerator 1, the water pump 2, the temperature sensor 4 and the flow meter 7 are arranged upstream of the device to be cooled in terms of the flow direction of the water in the pipeline.
This embodiment is through setting up the flowmeter 7 of being connected with the control unit 3 respectively in the cooling pipeline 5 of different branches for the control unit 3 can learn the velocity of flow of water in the cooling pipeline 5 that carries out the cooling for each equipment of waiting to cool down, and according to information such as the temperature information that velocity of flow information and temperature sensor 4 return and adjust the refrigeration temperature of refrigerator 1 or the output of water pump 2, realizes more meticulous cooling control.
Therefore, the closer the sensor is arranged in the cooling pipeline 5 to the equipment to be cooled, the more the obtained information can reflect the flow speed and temperature of the water which is cooled by the current equipment to be cooled. Also based on the above considerations, the above embodiment sets the flow meter 7 on the inner wall of the cooling pipeline 5 at the device to be cooled, so as to provide a preferable implementation for further setting positions of the temperature sensor 4, where each of the cooling pipelines 5 for cooling different devices to be cooled is provided with a temperature sensor 4 specifically: the temperature sensor 4 is arranged on the inner wall of a cooling pipeline 5 at the position of equipment to be cooled.
This embodiment is through setting up the temperature sensor 4 in cooling pipeline 5 treating cooling device department to the temperature in the current branch road of more accurate detection, thereby the more accurate control cooling process of the temperature information that the control unit 3 of being convenient for can return according to temperature sensor 4.
In addition to the aforementioned embodiment in which different water pumps 2 are disposed on the branch where different devices to be cooled are located, as shown in fig. 2, this embodiment also provides a preferred embodiment, where the connection between the refrigerator 1 and the cooling pipeline 5 is specifically: each cooling pipeline 5 for cooling different equipment to be cooled is connected with a different refrigerator 1.
In order to further reduce energy consumption, the refrigerator 1 in this embodiment is preferably a variable frequency refrigerator, and is connected to the control unit 3, and after the control unit 3 obtains the water temperature corresponding to the current device to be cooled according to the received temperature information or flow information of each device to be cooled, the control unit sends a control signal to the variable frequency refrigerator to enable the variable frequency refrigerator to reduce the water in the cooling pipeline 5 to a specified temperature.
Because cooling pipeline 5 between the different branch roads is separated through valve 6, treat the cooling equipment and cool down before, the water in cooling pipeline 5 all does not communicate, so the water in the cooling pipeline 5 of different branch roads can have different temperature and velocity of flow, in the above-mentioned embodiment, provide the preferred scheme that each branch road was provided with different water pumps 2 respectively, with the purpose of the velocity of flow of water in the each branch road of realization control, and this embodiment is through setting up different refrigerator 1 on each branch road, can realize the purpose of the temperature of water in each branch road of control, thereby realize that each treats the cooling equipment for the cooling demand difference and carries out the cooling of pertinence, reach better cooling effect.
To further illustrate the apparatus provided in the present application, on the basis of the above examples, the present example also provides a preferred embodiment as follows: the valve 6 is a check valve.
The check valve is a one-way valve that only allows the liquid medium to flow through the check valve from the same direction, but prevents the liquid medium from flowing in the reverse direction. The check valve belongs to the automatic valve class, does not need external additional control, realizes the opening and closing of the opening and closing piece in the valve only by the flowing pressure of the liquid medium in the pipeline, and when the liquid medium flows in the direction allowing the circulation, the valve clack is opened under the pressure action of the liquid medium; when the liquid medium flows in the opposite direction, the valve clack acts on the valve seat by the pressure of the liquid medium and the self-superposition of the valve clack, and the flow of the liquid medium is cut off.
It should be noted that, in this embodiment, the specific type of the check valve is not limited, and may be a straight-through type, a lifting type, a swing type, a butterfly type, a diaphragm type, a ball type check valve, and the like.
The check valve can achieve the effect of preventing the backflow of liquid due to its unique structure. Get rid of and avoid because the palirrhea influence that leads to of water in the cooling pipeline 5 to refrigerator 1 and water pump 2 normal work, still make rivers flow in and carry out the each branch road of cooling to different equipment of waiting to cool down after, can not reverse flow into other branch roads again, make the rivers that correspond the branch road obtain from refrigerator 1 and water pump 2 and be adapted to behind the temperature and the velocity of flow that current branch road corresponds, can not influence other branch roads, and then, every branch road can all obtain required temperature and the velocity of flow of current branch road and need not consider the influence of other branch roads through corresponding water pump 2 and refrigerator 1, the differentiation of cooling control between the different equipment of waiting to cool down has further been guaranteed, realize better cooling effect.
Besides the water cooling through the cooling pipeline 5, the natural heat dissipation of the equipment to be cooled is also an important channel for heat discharge, and the cooling requirements of the equipment to be cooled are different at different environmental temperatures. In order to better control the temperature reduction process, on the basis of the above embodiment, this embodiment further provides a preferred embodiment, as shown in fig. 3, the temperature reduction device based on vacuum sublimation purification equipment provided by this application further includes:
and the environment temperature sensor 8 is arranged at the control unit 3, and the environment temperature sensor 8 is connected with the control unit 3 and used for acquiring the temperature information of the surrounding environment and returning the temperature information to the control unit 3.
Because the many works of vacuum sublimation purification equipment are indoor, the ambient temperature of its surrounding is comparatively stable and the temperature difference of different positions is not big, so do not have strict restriction to the specific position that sets up of ambient temperature sensor 8, but consider that wait to cool down the equipment and be equivalent to a heat source, and then flow through the cooling water in the cooling pipeline 5, all can produce certain influence to the temperature of surrounding, so for further accurate measurement ambient temperature, should set up ambient temperature sensor 8 in the place of keeping away from waiting to cool down equipment and cooling pipeline 5. Generally, the control unit 3 is not arranged too close to the equipment to be cooled and the cooling pipeline 5; meanwhile, in order to ensure the control effect, the control unit 3 and the equipment to be cooled are arranged in the same factory; in addition, the ambient temperature sensor 8 needs to be connected to the control unit 3, and is more conveniently disposed as the distance from the control unit 3 is closer. In summary, the ambient temperature sensor 8 is preferably disposed at the control unit 3 in the present embodiment, but it should be noted that the ambient temperature sensor 8 can be disposed at other positions to achieve the purpose of collecting the ambient temperature.
This embodiment is through gathering ambient temperature at setting up ambient temperature sensor 8 for the flow rate and the temperature of the water in the control unit 3 can suitably adjust cooling pipeline 5 according to current ambient temperature, for example reduce the temperature of water or improve the flow rate of water etc. when ambient temperature is higher, in order to satisfy the cooling demand of each equipment of waiting to cool down. When the ambient temperature is lower, too low water temperature or too high flow rate is not needed, the output power of the refrigerator 1 and the water pump 2 can be properly reduced to achieve the purposes of energy conservation and emission reduction, and therefore more refined control over the cooling process is achieved.
Similarly, considering that the cooling device provided by the present application is mainly applied to cooling of vacuum sublimation purification equipment, and the above also explains that too low temperature of the cooling pipeline 5 may cause condensed water vapor on the outer wall of the pipeline, so as to further increase the environmental humidity, and too high environmental humidity may cause serious influence on the purity of the product purified by vacuum sublimation, therefore, as shown in fig. 3, this embodiment further provides a preferred embodiment, and the cooling device based on vacuum sublimation purification equipment further includes:
set up in the humidity transducer 9 of cooling pipeline 5 outer wall, humidity transducer 9 is connected with the control unit 3 for gather the humidity information of surrounding environment, and return to the control unit 3.
When humidity is higher, in order to avoid leading to the vapor in the air to condense on the pipeline outer wall because of the low temperature of water in the cooling pipeline 5, make the vapor of surrounding environment can't get rid of, further increase ambient humidity, and then influence product purity, the control unit 3 can make the temperature suitably improve through the power of adjustment refrigerator 1, and the mode that the velocity of flow of water becomes fast in the mode messenger cooling pipeline 5 through control water pump 2, guarantee the cooling effect.
As with the above-described embodiment, the same is true for the installation position of the ambient temperature sensor 8, and this embodiment is also a preferable mode for the installation position of the humidity sensor 9, and considering that the outer wall of the cooling pipeline 5 is lower than the ambient environment, and the water vapor is more easily condensed on the outer wall of the cooling pipeline 5, so the humidity around the cooling pipeline 5 is also relatively higher, and the humidity sensor 9 is installed here, so that the situation that the humidity of the ambient environment is increased can be more easily and more timely detected. But, similarly, the purpose of acquiring the current environment humidity information can be satisfied by arranging the humidity sensor 9 at any position of the environment where the vacuum sublimation purification apparatus is located, and the arrangement of the position at the outer wall of the cooling pipeline 5 is only a preferred embodiment.
The advantages of this embodiment over the above embodiments are: acquire the humidity information of vacuum sublimation purification equipment surrounding environment through setting up humidity transducer 9, when humidity is too high, the control unit 3 suitably reduces the temperature of 5 interior waters of cooling pipe, and improve the velocity of flow, in order when guaranteeing the effect of cooling, avoid leading to the vapor in the air all to condense on 5 outer walls of cooling pipe because of the temperature is low excessively, make the vapor in the air can't discharge, and influence the problem of product purity, further guaranteed going on smoothly of vacuum sublimation purification process.
As can be seen from the above, the control unit 3 can adjust the power of the refrigerator 1 and the water pump 2 according to the water temperature information of each branch of the cooling pipeline 5 acquired by the temperature sensor 4, the environmental temperature information acquired by the environmental temperature sensor 8, the environmental humidity information acquired by the humidity sensor 9, and the like, and achieve the effect of adjusting the water temperature and the flow rate in the cooling pipeline 5, but this control method is not transparent enough, and an operator does not know the current situation in the cooling pipeline 5, nor does the control unit 3 know whether a fault or an error occurs, and the stability and the reliability of the cooling device are adversely affected, so as shown in fig. 3, on the basis of the above embodiment, this embodiment further provides a preferred embodiment, and the cooling device further includes: a display screen 10;
the display screen 10 is connected to the control unit 3 and is configured to display the temperature information and the humidity information of the ambient environment, the refrigeration state of the refrigerator 1, and the power information of the water pump 2, which are sent by the control unit 3.
As can be seen from the above, the control unit 3 is in communication connection with the temperature sensors 4 arranged at various positions in the cooling pipeline 5, the ambient temperature sensor 8 arranged in the control unit 3, the humidity sensor 9 arranged on the outer wall of the cooling pipeline 5, the flow meter 7, the refrigerator 1, the water pump 2 and the like, and can acquire the water temperature and flow rate, the ambient temperature and ambient humidity of each branch of the cooling pipeline 5, the refrigeration state of the refrigerator 1, the power information of the water pump 2 and the like. These information help operating personnel to judge the current overall condition of heat sink to judge whether the heat sink breaks down or can satisfy the cooling demand in view of the above.
It should be noted that, the information displayed on the display screen 10 in this embodiment is only a preferred scheme, and the present embodiment does not limit this, if the control unit 3 is connected to other devices or needs to display other data and parameters.
The advantages of this embodiment over the above embodiments are: through setting up information such as the temperature in the display screen 10 demonstration each branch road, velocity of flow, ambient temperature, ambient humidity, and the state of refrigerator 1 and the power of water pump 2, the operating personnel of being convenient for masters the current state of heat sink, and then can carry out fault diagnosis, or rely on above-mentioned information that obtains to carry out manual control to the cooling process, further improved the reliability and the stability of cooling process.
