Detailed Description
The invention will be further illustrated by means of specific embodiments in the following description with reference to the accompanying drawings:
referring to fig. 1, an architecture of an embodiment of a machine-cabin-level flow-adjustable mixing pipeline system is schematically shown, and the system comprises a water inlet main pipe 1, a water outlet main pipe 2 and a pipeline unit, wherein the pipeline unit comprises a water inlet branch pipe 3, a water outlet branch pipe 4 and a plurality of branch circuits, the branch circuits are connected with quick connectors, and the branch circuits are used for being instantly cut off and communicated with the water inlet branch pipe 3, the water outlet branch pipe 4 or a heat dissipation device through the quick connectors; the water inlet branch pipe 3 and the water outlet branch pipe 4 are arranged in series, and cooling water can sequentially pass through the water inlet main pipe 1, the water inlet branch pipe 3, the water outlet branch pipe 4 and the water outlet main pipe 2 to form a main circulation loop; the branch circuits are arranged between the water inlet branch pipe 3 and the water outlet branch pipe 4 in parallel, and cooling water can sequentially pass through the water inlet main pipe 1, the water inlet branch pipe 3, the branch circuits, the water outlet branch pipe 4 and the water outlet main pipe 2 to form a plurality of branch circulation loops. As can be seen from fig. 1, for a single machine room, there are two mixing pipeline systems, each having a pipeline unit, and the branch of each pipeline unit forms two branch collecting areas, as can be seen from fig. 2 and 3, the branches of the two pipeline units cover the front and left two areas and the rear and right two areas of the machine room, respectively. The four areas of the front, the rear, the left and the right of the machine cabin are also installation positions of the heat dissipation equipment, and the branch is used for leading cooling water into and out of the heat dissipation equipment so as to help the machine cabin to dissipate heat.

In the invention, the pipeline unit is mainly used for arranging the branch circuits near the heat dissipation equipment in a combined mode on the premise of fully utilizing the limited installation space of the machine cabin. Like this embodiment, have two pipe-line system, have two pipeline units, the branch road of every pipeline unit arranges respectively in two adjacent regions in the preceding, back, left and right lateral zone of machine storehouse, and this is the preferred scheme that the effect is better relatively, has both let two pipeline units cover whole region, makes the pipeline overall arrangement accomplish succinct as far as again, sets up comparatively simply to all there is good performance in hierarchical regulation and control ability, the heat dissipation equilibrium. Of course a single pipe unit may add a branch collection area to cover three or all of the front, rear, left and right side areas of the cabin. It is preferable that the branch of the single pipe unit covers at least two of the front, rear, left and right side regions of the cabin, and further, it is preferable that the branch of the single pipe unit covers two adjacent regions of the front, rear, left and right side regions of the cabin.
The water inlet branch pipe 3 comprises a plurality of branch water inlet connecting pipe sections, the water outlet branch pipe 4 comprises a plurality of branch water outlet connecting pipe sections, the branch water inlet connecting pipe sections and the branch water outlet connecting pipe sections are in one-to-one correspondence and are arranged in pairs, and the branch water inlet connecting pipe sections and the branch water outlet connecting pipe sections which are arranged in pairs are arranged between the branch water inlet connecting pipe sections and the branch water outlet connecting pipe sections. The branch water inlet connecting pipe sections and the branch water outlet connecting pipe sections are connected through transition pipe sections, and in addition, the branch water inlet branch pipes 3 and the branch water outlet branch pipes 4 can be connected through transition pipe sections, and can be regarded as the branch water inlet connecting pipe sections and the corresponding branch water outlet connecting pipe sections. The branch water inlet connecting pipe section and the branch water outlet connecting pipe section are both relatively long water pipes, usually hard straight pipes, and are matched with each other to form a branch collecting area; the transition pipe sections are usually relatively short water pipes for connection, and include a switching elbow, a non-stripping hose and the like.
Although it is apparent from fig. 1 that two pairs of branch water inlet connecting pipe sections and branch water outlet connecting pipe sections are provided for each pipe unit, that is, a side region of the machine cabin corresponds to a branch collecting region, the number of pairs of branch water inlet connecting pipe sections and branch water outlet connecting pipe sections may be more, that is, a side region of the machine cabin may have a plurality of branch collecting regions, fig. 2 ~ is a specific example of this manner, fig. 5 thus illustrates a case where two branch collecting regions are provided in left and right side regions of the machine cabin, two pairs of branch water inlet connecting pipe sections and branch water outlet connecting pipe sections are provided, one branch collecting region is provided in front and rear regions of the machine cabin, and one pair of branch water inlet connecting pipe sections and branch water outlet connecting pipe sections are provided, the three pairs of branch water inlet connecting pipe sections and branch water outlet connecting pipe sections are provided, and the branch water inlet connecting pipe sections are represented by a, b, c, and the branch water inlet connecting pipe sections are represented by a ', b ', c ' and the branch water outlet connecting pipe sections are provided in the schematic diagrams of fig. 2, 3 and the specific layout diagrams of fig. 4 and 5.
The relationship of several valves to the circuit is seen in conjunction with fig. 1, 2, and 3.
The water inlet branch pipe 3 and the water outlet branch pipe 4 are two concepts which exist relatively, a second regulating valve Y is arranged on a transition pipe section between the water inlet branch pipe 3 and the water outlet branch pipe 4, the pipe section before the second regulating valve Y can be regarded as the water inlet branch pipe 3 by taking the valve as a boundary point, and the pipe section behind the second regulating valve Y can be regarded as the water outlet branch pipe 4. The second regulating valve Y is generally only required to be provided with one valve, when the second regulating valve Y is closed, the water inlet branch pipe 3 and the water outlet branch pipe 4 are cut off and are mutually independent, and at the moment, all branches are required to be communicated, so that cooling liquid circulates on the branch circulation loop and flows through the heat dissipation equipment, which is also a loop in a normal working state; when the cooling system is opened, all branches do not need to be communicated or part of the branches are communicated, so that all or part of the cooling liquid circulates on the main circulation loop, and a bypass water path is formed.
The transition pipe sections between the adjacent branch water inlet connecting pipe sections and the transition pipe sections between the adjacent branch water outlet connecting pipe sections are respectively provided with a first regulating valve X, and the two transition pipe sections are generally respectively provided with one first regulating valve X. The first control valve X directly serves to regulate the flow on the branched circulation circuit and to interrupt the flow in the downstream branch collecting region (the lowest branch collecting region of the line unit in the view of fig. 1). Adjusting the opening degree of the first regulating valve X, wherein if the opening degree is small, the flow in the branch before the first regulating valve X is relatively increased, the heat dissipation capacity of the heat dissipation equipment at the corresponding position is improved, the flow in the branch after the first regulating valve X is limited, and the heat dissipation capacity of the heat dissipation equipment at the corresponding position is reduced; if the opening degree is larger, the opposite is true. Naturally, the first control valve X can also be closed completely, so that the branch circuit located behind it is completely shut off, i.e. the heat sink device in the corresponding location does not need to work, and there is no heat dissipation requirement in this location. Therefore, the first regulating valve X is mainly used for meeting the heat dissipation requirements of heat dissipation areas on different sides of the machine cabin, so that balanced regulation is achieved, and high efficiency and energy conservation are guaranteed.
Third regulating valves Z are arranged on the transition pipe sections between the water inlet branch pipe 3 and the water inlet main pipe 1 and the transition pipe sections between the water outlet branch pipe and the water outlet main pipe 2, and the two transition pipe sections are generally respectively provided with one third regulating valve Z. And the third regulating valve Z is directly responsible for the on-off of the main circulation loop and the branch circulation loop of the pipeline unit. Of course, adjusting the opening degree can also affect the flow in all the pipelines behind the first control valve like the first control valve X, that is, the overall heat dissipation effect.
Particularly, the branch comprises a primary hose 6 for water inlet and outlet from the heat dissipation equipment, one end of the primary hose 6 for water inlet is connected with the branch water inlet connecting pipe section, and one end of the primary hose 6 for water outlet is connected with the branch water outlet connecting pipe section. The two ends of the primary hose 6 are connected with quick connectors, the quick connectors are plug-in connectors capable of achieving on-off under pressure in real time, and accordingly, the connectors matched with each other can be arranged on the radiating equipment, the branch water inlet connecting pipe section and the branch water outlet connecting pipe section. Therefore, when the flow and the access of the regulating valve are regulated and controlled, each branch can be freely switched on and off through the primary hose 6, multi-stage regulation is realized together with the valve, and different heat dissipation requirements of different areas are met. All 204 branches of the left pipeline unit and 136 branches above the right pipeline unit in fig. 1 are the branches, so that the setting cost is relatively low, the layout is simple, and the maintainability is high. In addition, the first-stage hose 6 may have different pipe diameters, for example, the pipe diameters of the first-stage hose 6 in the upper branch collecting region of the left pipeline unit and the first-stage hose 6 in the lower branch collecting region are two different pipe diameters, which mainly depend on the kind of the heat dissipation device at the corresponding position.
The other branch comprises a primary hose 6, a secondary hose 7 and water collecting and distributing devices 8 which are used for respectively feeding and discharging water from two ends of the heat radiating equipment, wherein each water collecting and distributing device 8 corresponds to a plurality of groups of primary hoses 6 and a plurality of secondary hoses 7 for feeding and discharging water; the water collecting and distributing device 8 is arranged between the water inlet one-level hose 6 and the branch water inlet connecting pipe section and between the water outlet one-level hose 6 and the branch water outlet connecting pipe section, the branch water inlet connecting pipe section, the branch water outlet connecting pipe section and the corresponding water collecting and distributing device 8 are connected through a plurality of second-level hoses 7, one end of the water inlet one-level hose 6 is connected with one water collecting and distributing device 8, and one end of the water outlet one-level hose 6 is connected with the other water collecting and distributing device 8. The two ends of the first-level hose 6 and the second-level hose 7 are connected with quick connectors, correspondingly, matched connectors are arranged on the heat dissipation device, the branch water inlet connecting pipe section, the branch water outlet connecting pipe section and the water collecting and distributing device. The 36 branches below the right-hand line unit in fig. 1 are all such branches. Although such an arrangement is complicated from the perspective of the architecture, the practical situation is that installation space can be more reasonably utilized by introducing the water collecting and distributing device 8, the key is to arrange enough branches in a limited space and to equalize the flow as much as possible, the pipeline layout is still simple, and only the cost is correspondingly improved, which will be explained later with reference to fig. 4 and 5. And, second grade hose 7 is the same with first-level hose 6, also can select different pipe diameter settings, also can help the branch road to realize freely the break-make, reaches the effect of multistage regulation.
Regarding the water collector 8, it includes the water inlet pipe section 81 and the water outlet pipe section 82 that set up perpendicularly each other specifically, can refer to fig. 5, be equipped with on water inlet pipe section 81 and the water outlet pipe section 82 with the branch road water inlet connecting pipe section or the branch road water outlet connecting pipe section or the fixed connection's of other installation face connecting portion, the perpendicular setting is for the installation environment of adaptation machine storehouse and the conventional station setting of adaptation heat dissipation equipment, rationally utilize the assembly space, when laminating machine storehouse itself and some other casing installation faces in it, the cooperation heat dissipation equipment is from horizontal diversion to vertical diversion, be convenient for connect and operate. The length of the water outlet pipe section 82 is conventionally set to be larger than that of the water inlet pipe section 81, because the number of the primary hoses 6 is relatively more, the primary hoses are directly connected with the heat dissipation equipment in a quick plug-in manner, the water inlet and outlet amount of the main regulating branch of the secondary hose 7 can be relatively reduced in a limited space, and therefore multi-stage regulation can be completed, and the space can be reasonably utilized. When the water collecting and distributing device 8 is arranged between the primary hose 6 for water inlet and the branch water inlet connecting pipe section and between the primary hose 6 for water outlet and the branch water outlet connecting pipe section, the top surfaces of the water outlet pipe sections 82 of the paired water collecting and distributing devices 8 corresponding to the same group of primary hoses 6 for water inlet and outlet are completely attached and fixed (the top surfaces are completely overlapped and attached to be matched with the pipe sections vertically, which is the mode of saving the installation space), and then all the devices are fixed on the corresponding branch water inlet connecting pipe sections or all the devices are fixed on the corresponding branch water outlet connecting pipe sections.
Certainly, the water collecting and distributing device 8 can be only used for connecting the primary hose 6 for water inlet and the branch water inlet connecting pipe section, the branch water inlet connecting pipe section is connected with the water collecting and distributing device 8 through a plurality of secondary hoses 7, one end of the primary hose 6 for water inlet is connected with the water collecting and distributing device 8, and one end of the primary hose 6 for water outlet is connected with the branch water outlet connecting pipe section; the water collecting and distributing device 8 can also be only used for connecting the primary hose 6 for water outlet and the branch water outlet connecting pipe section, the branch water outlet connecting pipe section is connected with the water collecting and distributing device 8 through a plurality of secondary hoses 7, one end of the primary hose 6 for water inlet is connected with the branch water inlet connecting pipe section, and one end of the primary hose 6 for water outlet is connected with the water collecting and distributing device 8. The water collecting and distributing device 8 is used for completing the balanced arrangement of the branches in the limited installation space of the machine cabin and simultaneously realizing the multi-stage adjustment of the branches. Some areas of the machine cabin can be free from introducing water collecting and distributing devices 8, but pipeline units in the whole technical scheme of the invention can be completely and effectively arranged, and the water collecting and distributing devices 8 are more critical and are the precondition for conveniently and simply arranging enough branches based on the installation space of the existing machine cabin and stations of heat dissipation equipment in the installation space.
