Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
At present, in view of the advantage of high heat dissipation efficiency of refrigerant heat dissipation, the heat dissipation form of the electric control board 011 of the air conditioner mostly adopts refrigerant heat dissipation, and the indirect heat exchange is mainly performed between the low-temperature characteristic of the refrigerant medium and the electric control board 011.
Specifically, referring to fig. 1, refrigerant heat abstractor 02 includes refrigerant copper pipe 021, first radiator 022 and second radiator 023, and automatically controlled box includes automatically controlled board 011 and the plastic support 012 of the automatically controlled board 011 of installation, and automatically controlled board 011 and plastic support 012 constitute automatically controlled subassembly 01, and screw 03 passes automatically controlled board 011, plastic support 012 and second radiator 023 and fastens on first radiator 022. Wherein, refrigerant copper pipe 021 passes first radiator 022, and refrigerant heat medium flows in refrigerant copper pipe 021 and circulates, and second radiator 023 and automatically controlled board 011 carry out effective isolation through plastic support 012, and contact with the radiating element on the automatically controlled board 011 and carry out the heat exchange to reduce the temperature of automatically controlled board 011.
However, since the thermal conductivity of the screw 03 is high, and one end of the screw 03 is fastened to the first heat sink 022, and the other end of the screw 03 is fastened to the electronic control board 011, in this way, under long-time operation, the temperature of the screw 03 is similar to that of the second heat sink 023, and since the head of the screw 03 is still exposed inside the electronic control box, the air inside the electrical box is prone to generating condensation when encountering the screw 03 with low temperature, so that the electronic control board 011 cannot normally operate or is damaged. For example: the environmental temperature is 25 ℃, the dew point temperature is 20 ℃, the temperature of the inlet water is 10 ℃, the temperature of the second radiator 023 and the temperature of the screw 03 are only 19 ℃ and are lower than the dew point temperature, so that the air in the electric control box meets the exposed screw 03 on the electric control board 011, condensate water is generated, and the electric control board 011 cannot work normally or is damaged.
To the above problem, the embodiment of the utility model provides an automatically controlled box to form a large amount of comdenstions water and lead to the unable normal work of automatically controlled board or the problem of damage on the screw of the inside of solving automatically controlled box.
The embodiment of the utility model provides a pair of automatically controlled box, refer to fig. 2, including automatically controlled subassembly 1, automatically controlled subassembly 1 is connected with low temperature heat abstractor 2, and automatically controlled subassembly 1 passes through 3 fixed connection of screw with low temperature heat abstractor 2, and screw 3 is close to one of automatically controlled subassembly 1 and serves and be equipped with adiabatic sealing member 4, and adiabatic sealing member 4 is used for keeping apart the one end and the air that screw 3 is close to automatically controlled subassembly 1.
The utility model discloses automatically controlled box, as shown in fig. 2, including automatically controlled subassembly 1, automatically controlled subassembly 1 is connected with low temperature heat abstractor 2, and low temperature heat abstractor 2 is lower than the temperature in automatically controlled subassembly 1 for carry out the heat exchange with automatically controlled subassembly 1, thereby reduce the temperature of automatically controlled subassembly 1. The electric control assembly 1 and the low-temperature heat dissipation device 2 are fixedly connected through a screw 3, a part of the screw 3 is exposed on the surface of the electric control assembly 1, a heat insulation sealing piece 4 is arranged at one end, close to the electric control assembly 1, of the screw 3, the heat insulation sealing piece 4 is used for isolating one end, close to the electric control assembly 1, of the screw 3 from air, and namely the heat insulation sealing piece 4 isolates the screw 3 exposed on the surface of the electric control assembly 1 from air. In this case, the heat insulating seal 4 isolates the air from the exposed screws 3 on the electronic control assembly 1, and because the heat conductivity coefficient of the heat insulating seal 4 is extremely low, the temperature of the heat insulating seal is close to the ambient temperature, so that the phenomenon that the air meets a low-temperature object to generate water condensation is avoided. Compared with the prior art, the utility model discloses automatically controlled box through set up adiabatic sealing member 4 on exposing the screw 3 on the surface at automatically controlled subassembly 1, the inside air of having solved automatically controlled box meets 3 formation of low temperature screws and forms a large amount of comdenstions water and leads to the unable normal work of automatically controlled board 11 or the problem of damage.
It should be noted that, the following description is given by taking the electric control box in the air conditioner as an example, and the purpose is to more clearly illustrate the embodiment of the present invention, which cannot constitute a limitation to the implementation scope of the present invention. In some embodiments of the air conditioner, referring to fig. 2, the electronic control assembly 1 at least includes an electronic control board 11 and a housing 12 for mounting the electronic control board 11, the low-temperature heat sink 2 includes a refrigerant copper pipe 21, a first heat sink 22 and a second heat sink 23, and the screw 3 is fastened to the first heat sink 22 through the electronic control board 11, the housing 12 and the second heat sink 23.
The utility model discloses automatically controlled box of embodiment, refer to fig. 2, in order to keep apart the air in exposed screw 3 and casing 12 on the automatically controlled board 11, above-mentioned adiabatic sealing member 4 can adopt integrative adiabatic sealing member 4 cover in the top of the one end that screw 3 is close to automatically controlled subassembly 1 with screw 3's one end and air isolation, in order to wrap up the one end that screw 3 is close to automatically controlled subassembly 1 completely, at this moment, adiabatic sealing member 4 should with automatically controlled subassembly 1 fixed connection, and the junction should have good gas tightness, satisfy the selection of the connection of above-mentioned requirement and not only, can be the bonding of welding or the gas tightness, consider that the bonding has the simple and convenient and simple advantage of used equipment of technology, so adopt the mode of bonding to make adiabatic sealing member 4 should with automatically controlled subassembly 1 fixed connection. Specifically, the heat insulating seal 4 is adhered to the electronic control assembly 1, and completely wraps the end of the screw 3 close to the electronic control assembly 1. At this time, the screws 3 are completely isolated from the air in the housing 12, so that the hot air in the housing 12 cannot meet the exposed low-temperature screws 3 on the electric control board 11, thereby preventing a large amount of condensed water from being formed on the low-temperature screws 3. The heat insulating seal 4 is fixedly connected to the electronic control unit 1 by bonding, and the bonded joint has good air tightness and good insulation.
The electric control board 11 is one of the main components of the air conditioner, and needs to be repaired or replaced later, especially when the electric control board 11 needs to be disassembled, the screw 3 can be disassembled after the heat insulation sealing member 4 is damaged. In addition, when the heat insulating seal 4 is mounted, the heat insulating seal 4 can be sealingly bonded to the electric control board 11 only after the screws 3 are fastened to the first heat sink 22 through the electric control board 11, the case 12, and the second heat sink 23, which complicates the mounting process. Therefore, in order to facilitate the installation, maintenance and replacement of the electronic control panel 11, the top of the heat insulating seal 4 should be provided with a detachable connector, and the screw 3 can be detached after the connector is removed. Specifically, as shown in fig. 2 and 3, the heat insulating seal 4 includes a sealing base 41 circumferentially distributed along one end of the screw 3 close to the electronic control assembly 1, and a sealing plug 42 located above a top portion of one end of the screw 3 close to the electronic control assembly 1, wherein the sealing base 41 is detachably connected to the sealing plug 42. Based on this, when the electric control board 11 is mounted or dismounted, the sealing plug 42 is separated from the sealing base 41, and the mounting and dismounting of the screw 3 can be directly realized; when the screw 3 is fastened to the electronic control board 11, the screw 3 can be completely isolated from the air in the housing 12 by directly connecting the sealing plug 42 with the sealing base 41. Therefore, the process of mounting and dismounting the electric control board 11 is simple, and the operation is convenient.
In addition, the electronic control board 11 is a center of a complex electronic system of the air conditioner, and great care is taken in the process of installation, maintenance or replacement of the electronic control board 11. However, during the installation, maintenance or replacement of the electronic control board 11, the screw blade is easily disengaged from the groove of the screw 3 when it is deflected, and thus, it may touch the electronic control board 11, which may damage the electronic control board 11. Therefore, in order to prevent the screw driver from hitting the electric control plate 11, referring to fig. 4, the axial length of the seal base 41 is greater than or equal to the axial length of the screw 3. Therefore, the installation and the disassembly of the screw 3 are completed in the sealing base 41, and even if the screwdriver is disengaged from the thread groove on the screw 3 in the installation and the disassembly processes of the screw 3, the screwdriver cannot touch the electric control board 11 outside the sealing base 41 to cause the damage of the electric control board 11. In addition, because the axial length of the sealing base 41 is greater than or equal to the axial length of the screw 3, when the screw 3 is screwed by the screw driver, the sealing base 41 has a certain guiding function on the screw driver, so that the probability of the deviation of the screw driver in the process of screwing the screw 3 by the screw driver is reduced, and the situation that the screw driver is separated from the screw groove on the screw 3 is reduced.
The sealing base 41 and the sealing plug 42 are detachably connected, and usually, a clamping manner is adopted, and clamping structures are various, for example:
the first method is as follows: referring to fig. 3, 4 and 6, the sealing plug 42 includes a sealing cover 421 abutting against the top surface of the sealing base 41 and a sealing post 422 fitted to protrude into the sealing base 41; the inner surface of the sealing base 41 is provided with a convex ring, the side surface of the plugging column 422 is provided with a convex point, and the convex ring is correspondingly clamped with the convex point. Specifically, when the sealing plug 42 is snapped with the sealing base 41, the sealing cover 421 abuts against the top surface of the sealing base 41 to limit the movement of the sealing plug 42 toward the inside of the sealing base 41; the side of the protruding point of the side of the sealing post 422 away from the electrical control board 11 abuts against the protruding ring of the inner surface of the sealing base 41 to limit the movement of the sealing plug 42 towards the outside of the sealing base 41.
The second method comprises the following steps: as shown in fig. 3, 4 and 6, the sealing plug 42 includes a sealing cover 421 abutting against the top surface of the sealing base 41 and a sealing post 422 fitted to protrude into the sealing base 41; the inner surface of the sealing base 41 is provided with a convex point 411, the side surface of the sealing column 422 is provided with a convex ring 4221, and the convex point 411 is correspondingly clamped with the convex ring 4221. Specifically, when the sealing plug 42 is snapped with the sealing base 41, the sealing cover 421 abuts against the top surface of the sealing base 41 to limit the movement of the sealing plug 42 toward the inside of the sealing base 41; the side of the collar 4221 of the side of the sealing column 422 remote from the electrical control board 11 abuts against the raised point 411 of the inner surface of the sealing base 41 to limit the movement of the sealing plug 42 out of the sealing base 41.
In order to form a stable engagement between the sealing base 41 and the sealing plug 42, four protrusions are provided on the side surface of the sealing post 422 or the protrusions 411 provided on the inner surface of the sealing base 41, and are uniformly distributed along the circumferential direction. At this time, when the sealing plug 42 and the sealing base 41 are clamped together, the sealing plug 42 and the sealing base 41 will not shake under the action of the convex ring and the four convex points.
It should be understood that, compared with the clamping structure of the convex ring and the convex ring, the clamping structure of the convex ring and the convex ring has lower operation difficulty for clamping or separating, and the clamping structure of the convex ring and the convex ring has higher operation difficulty for clamping or separating; because the sealing plug 42 is usually not subjected to the force for separating the sealing base 41 after being clamped with the sealing base 41, in order to facilitate the operation, a clamping structure of a salient point and a convex ring is adopted, and the clamping and separating operation of the sealing base 41 and the sealing plug 42 is more convenient and faster.
Because the sealing plug 42 is small, after the sealing plug 42 is separated from the sealing base 41, a fixed storage position is not provided, and the sealing plug 42 is easy to lose when the main control board is mounted or dismounted. In order to solve the above problem, as shown in fig. 3, a flexible connecting member 43 is provided between the sealing base 41 and the sealing plug 42, one end of the flexible connecting member 43 is connected to the sealing base 41, and the other end is connected to the sealing plug 42. At this time, when the main control board is mounted or dismounted, after the sealing plug 42 is separated from the sealing base 41, the sealing plug 42 is still connected with the sealing base 41 through the flexible connecting piece 43, and the mounting or dismounting of the screw 3 is not affected; when the sealing plug 42 and the sealing base 41 are required to be clamped, the sealing plug 42 connected to the position near the sealing base 41 through the flexible connecting piece 43 is directly moved to the sealing base 41 to be clamped, so that the operation is convenient, and the sealing plug is not easy to lose.
It is understood that the heat insulating seal 4 may be broken after a long period of use, so that the screw 3 is not completely isolated from the air in the housing 12, and the isolation effect is not good, and therefore, it is necessary to replace the heat insulating seal 4 with a new one. However, when the heat insulating seal 4 is bonded to the electric control board 11, the glue is difficult to clean and difficult to replace. Therefore, referring to fig. 3 and 5, a clamping portion 44 extends from one end of the sealing base 41 away from the sealing plug 42 to a direction away from the sealing plug 42, fixing holes 5 for being matched with the screws 3 are formed in the electronic control assembly 1 and the low-temperature heat dissipation device 2, a clamping structure matched with at least one fixing hole 5 is formed in the outer surface of the clamping portion 44, and the clamping structure is used for clamping the sealing base 41 on the electronic control assembly 1. In this case, the heat insulating seal 4 is detachably attached to the electric control board 11 by engaging with the fixing hole 5.
Specifically, the external clamping structure of the clamping portion 44 may be two convex rings disposed on the external side of the clamping portion 44, and one of the two convex rings, which is far from the sealing plug 42, is extruded to pass through the fixing hole 5 on the electronic control board 11, so that the two convex rings are respectively located on two sides of the electronic control board 11, and the sealing base 41 is clamped on the electronic control board 11; the external clamping structure of the clamping portion 44 may also be a screw thread 441 disposed on the external side surface of the clamping portion 44, and the screw thread 441 is screwed into the fixing hole 5 on the electronic control board 11, so that the sealing base 41 is clamped on the electronic control board 11, or the screw thread 441 is screwed onto the second heat sink 23 from the fixing hole 5 on the electronic control board 11, so that the sealing base 41 is clamped with the electronic control assembly 1 and the low-temperature heat dissipation device 2. Therefore, referring to fig. 2, 4 and 5, the clamping structure is a screw thread 441 on the outer side surface of the clamping portion 44, and first, the clamping operation is simpler than the clamping structure is two convex rings disposed on the outer side surface of the clamping portion 44; secondly, the screw thread 441 can be directly screwed into the second heat sink 23, so that the sealing base 41 is clamped with the electronic control assembly 1 and the low-temperature heat dissipation device 2, and the fixing effect is better. Therefore, the clamping structure is the screw thread 441 arranged on the outer side surface of the clamping portion 44, the screw thread 441 is clamped with the electric control assembly 1 and the two corresponding fixing holes 5 on the low-temperature heat dissipation device 2, the clamping operation is simple and convenient, and the clamping effect is good.
It should be understood that the outer side of the clamping portion 44 is in fit clamping with the fixing hole 5, and in order to ensure that the screw 3 passes through the electric control board 11, the housing 12 and the second heat sink 23 inside the heat insulation sealing member 4 and is fastened to the first heat sink 22, as shown in fig. 5 and 6, the inner side of the clamping portion 44 is provided with a through hole 442 in fit fixing with the screw 3. Referring to fig. 4 and 5, the through hole 442 fixed in cooperation with the screw 3 means that the diameter of the screw body of the screw 3 is smaller than the diameter of the through hole 442 in the clamping portion 44, so as to ensure that the screw body of the screw 3 can extend into the through hole 442 in the clamping portion 44; the diameter of the head of the screw 3 is larger than the through hole 442 of the clamping portion 44. At this time, referring to fig. 2, 4 and 5, when the screw 3 is fastened to the first heat sink 22 through the electronic control board 11, the housing 12 and the second heat sink 23, a portion of the screw body of the screw 3 extends into the through hole 442 inside the snap-in portion 44 and is fastened to the first heat sink 22, and the head of the screw 3 abuts against the through hole 442 of the snap-in portion 44, thereby fastening the electronic control assembly 1 and the low temperature heat sink 2 together.
The heat insulating seal is made of a heat insulating material, and may be made of glass fiber, plastic, rubber, or the like, and is generally made of plastic because plastic is relatively easy to be plastic due to its low cost.
