Description

Technical Field

[0002] High power and high integration are important trends in modern radar development. With the continuous iteration and upgrading of radar products, T / R components have shifted from traditional brick-like structures to tile-like digital ones, resulting in smaller subarray units but higher power consumption, leading to a continuous increase in system heat flux density. Liquid cooling, as an efficient heat dissipation method, has been widely used in radar products. Higher integration means more liquid-using units and a more compact flow channel layout, resulting in uneven flow distribution and structural layout difficulties. As radar structures continue to develop towards higher strength and lighter weight, these problems become increasingly apparent.

[0003] Existing flow distribution technologies use a traditional one-line module-one-way-out approach, which results in low flow channel utilization, is not suitable for high-density components, and has a complex structure for individual liquid cooling plate devices, which is not conducive to lightweight design.

[0028] Specifically, the liquid supply branch channel 21 includes a liquid supply branch groove 2101 formed on the surface of the distribution plate 1, and a liquid supply branch cover plate 2102 is attached to the liquid supply branch groove 2101; wherein, the first protrusion 53 is located on the outer side of the bottom of the liquid supply branch groove 2101, and a gap is formed between the first protrusion 53 and the liquid supply branch groove 2101; the liquid supply main channel 3 includes a liquid supply groove 301 formed on the surface of the distribution plate 1, and a liquid supply cover plate 302 is attached to the liquid supply groove 301. The liquid supply cover plate 302 and the liquid supply branch cover plate 2102 are located on the same side of the distribution plate 1, and the liquid supply cover plate 302 is connected to the liquid supply branch cover plate 2102; wherein, the liquid supply cover plate 302 is integrally formed with all the liquid supply branch cover plates 2102, serving as the liquid supply channel cover plate.

[0029] The return liquid branch channel 22 includes a return liquid branch groove 2201 formed on the surface of the distribution plate 1, and a return liquid branch cover plate 2202 is attached to the return liquid branch groove 2201; wherein, the first protrusion 53 is located on the outer side of the bottom of the return liquid branch groove 2201; the return liquid main channel 4 includes a return liquid groove 401 formed on the surface of the distribution plate 1, and a return liquid cover plate 402 is attached to the return liquid groove 401.

The depth of the supply groove 301 and the return liquid groove 401 is the same and is greater than the depth of the branch groove 201. The main liquid supply channel 3 is formed by overlapping the liquid supply cover plate 302 onto the liquid supply groove 301 and forming a sealed channel through welding, which facilitates processing and ensures the sealing performance of the channel. The main return channel 4 is formed in the same way as the main liquid supply channel 3, and will not be described again here.

[0030] In this embodiment, by creating supply branch grooves 2101, 301, 2201, and 401 on the surface of the distribution plate 1 and covering them with corresponding cover plates to form corresponding flow channels, the structural strength and flow area can be increased. Furthermore, by setting square supply branch grooves 2101, 301, 2201, and 401, the main supply flow channel 3, supply branch flow channel 21, main return flow channel 4, and return branch flow channel 22 are ensured to have a large flow area, reducing the weight of the distribution plate 1. Pressure loss; the depth of the liquid supply groove 301 and the liquid return groove 401 is greater than the depth of the liquid supply branch groove 2101. The distribution plate 1 is also provided with a groove 201. The groove 201 is arranged opposite to the liquid supply branch groove 2101 and the liquid return branch groove 2201 on the distribution plate 1. That is, the upper and lower surfaces of the distribution plate 1 are provided with the liquid supply branch groove 2101 (or the liquid return branch groove 2201) and the groove 201, so that the distribution plate 1 has an I-shaped structure at the middle liquid supply branch flow channel 21 (or the liquid return branch flow channel 22), which has a simple structure and high load-bearing strength.

[0031] Based on the above embodiment, the distribution plate 1 has multiple through holes 7, the number of which is the same as the number of sub-array cold plate assemblies 5. The through holes 7 are located at the sub-array cold plates 51 and are smaller than the sub-array cold plates 51. This reduces the weight of the distribution plate 1 and achieves lightweighting of the flow distribution device. Furthermore, the sub-array cold plate assemblies are fixed to the distribution plate 1 between the through holes 7 by screws. To further reduce weight, the thickness of the distribution plate 1 between the through holes 7 is less than the thickness of the distribution plate 1 at other locations.

[0032] The liquid-cooled connector 6 includes a connector socket 61 and a connector plug 62 that are interconnected. The connector socket 61 is fixed to the outer surface of the liquid supply branch channel 21 (or the liquid return branch channel 22) and communicates with the liquid supply branch channel 21. The connector plug 62 is fixed to the first protrusion 53 and communicates with the sub-array channel 52. For example, the liquid-cooled connector 6 is a blind-mating type. In this embodiment, the liquid-cooled connector 6 can self-seal in both on and off states. The liquid-cooled connector 6 connects each liquid supply branch channel 21 and the liquid return branch channel 22 through the sub-array channel 52, making the sub-array cold plate 51 easy and quick to disassemble and install.

[0033] The distribution method of the integrated lightweight high-strength flow distribution device of this utility model specifically includes the following steps:

[0034] Step S1: Control the flow rate of the main supply channel 3 or the main return channel 4 so that the coolant enters each supply branch channel 21 from the main supply channel 3. The coolant in the supply branch channel 21 enters one end of all the sub-array channels 52 connected to it through the corresponding liquid cooling connector 6.

[0035] Step S2: The coolant entering each sub-array flow channel 52 enters the return branch flow channel 22 from the other end of the sub-array flow channel 52 through the corresponding liquid cooling connector 6, and merges into the return main flow channel 4.

[0036] The flow rate of the main liquid supply channel 3 is determined based on the total flow rate of all subarray cold plates 51, and the flow rate of the main liquid supply channel 3 is equal to the flow rate of the main liquid return channel 4.

[0037] Furthermore, when the flow distribution component includes two components, controlling the flow rate of the main supply channel 3 or the main return channel 4 includes:

[0038] The flow rate of each main liquid supply channel 3 is determined based on the number of sub-array cold plates 51 connected to each liquid supply branch channel 21; the flow rate of each main liquid return channel 4 is determined based on the number of sub-array cold plates 51 connected to each liquid return branch channel 22.

[0039] Based on the flow rate of the main supply channel 3 and the flow rate of the main return channel 4, control the flow rate of any three channels in the main supply channel 3 and the main return channel 4.

[0040] In this embodiment, by controlling the flow rate of the main liquid supply channel 3 and / or the main liquid return channel 4, the precise distribution of the flow rate of the entire array of cold plate components can be achieved without the need for additional flow rate adjustment devices.

[0041] The working principle of the flow distribution device will be introduced below, taking 1 and 2 flow distribution components as examples.

[0042] Example 1

[0043] An integrated lightweight and high-strength flow distribution device, such as Figure 4 As shown, the system includes a distribution plate 1, on which a flow distribution component is installed, comprising a first main supply channel 31 and a first main return channel 41. The system also includes two branch channels 21 and 22, namely a first supply branch channel 211, a second supply branch channel 212, a first return branch channel 221, and a second return branch channel 222. The system also includes three sub-array cold plate components, each comprising four sub-array cold plate components 5. Its working principle is as follows:

[0044] Coolant enters the first supply branch channel 211 and the second supply branch channel 212 through the first main supply channel 31. The first supply branch channel 211 simultaneously supplies coolant to the upper and lower rows of eight sub-array cold plate assemblies 5 connected to it. After passing through the sub-array channel 52 and undergoing heat exchange, the coolant flows through the lower four sub-array cold plate assemblies 5 into the lower second return branch channel 222, and through the upper four sub-array cold plate assemblies 5 into the upper first return branch channel 222. The first return flow channel 221 supplies coolant to the four lower sub-array cold plate assemblies 5 connected to the second supply flow channel 212. After passing through the sub-array flow channel 52 and undergoing heat exchange, the coolant flows through the four lower sub-array cold plate assemblies 5 into the first return flow channel 221 below. The coolant then flows through the first return flow channel 221 and the second return flow channel 222 to the first return main flow channel 41, and finally flows out of the system, thus completing the parallel supply and return of coolant to the 12 sub-array cold plates.

[0045] The specific flow control method is as follows: assuming that the flow rate required for a sub-array cold plate assembly 5 is a, and the total flow rate required for the entire array is 12a, by controlling the flow rate of the first liquid supply main channel 31 or the first liquid return main channel 41 to 12a, the flow rate of the 12 sub-array cold plates of the entire array can be a.

[0046] Example 2

[0047] An integrated lightweight and high-strength flow distribution device, such as Figure 5As shown, the system includes a distribution plate 1, on which two flow distribution components are provided: a first main supply channel 31, a second main supply channel 32, a first main return channel 41, and a second main return channel 42. Each of the supply branch channels 21 and the return branch channels 22 includes six channels: a first supply branch channel 211, a second supply branch channel 212, a third supply branch channel 213, and a fourth supply branch channel 214. 4. The fifth liquid supply branch channel 215 and the sixth liquid supply branch channel 216; the first liquid return branch channel 221, the second liquid return branch channel 222, the third liquid return branch channel 223, the fourth liquid return branch channel 224, the fifth liquid return branch channel 225, and the sixth liquid return branch channel 226; the sub-array cold plate assembly array consists of 11 sub-array cold plate assemblies 5, each sub-array cold plate assembly array includes 11 sub-array cold plate assemblies 5, for a total of 121 sub-array cold plate assemblies 5. Its working principle is as follows:

[0048] This embodiment has two supply channels and two return channels, namely a first main supply channel 31, a second main supply channel 32, a first main return channel 41, and a second main return channel 42. Coolant enters the first branch supply channel 211, the second branch supply channel 212, and the third branch supply channel 213 through the first main supply channel 31. Coolant enters the fourth branch supply channel 214, the fifth branch supply channel 215, and the sixth main supply channel 213 through the second main supply channel 32. Branch flow channel 216, the first liquid supply branch flow channel 211 simultaneously supplies liquid to the upper and lower rows of 22 sub-array cold plate assemblies 5 connected to this branch. After passing through the sub-array flow channel 52 and undergoing heat exchange, the coolant flows through the lower row of 11 sub-array cold plate assemblies 5 into the lower first return flow channel 221, and through the upper row of 11 sub-array cold plate assemblies 5 into the upper second return flow channel 222; similarly, the second liquid supply branch flow channel 212 flows through the sub-array cold plate assemblies 5 into the second return flow channel. 222 and the third return liquid branch channel 223; the third supply liquid branch channel 213 flows into the third return liquid branch channel 223 and the fourth return liquid branch channel 224 through the sub-array cold plate assembly 5; the fourth supply liquid branch channel 214 flows into the fourth return liquid branch channel 224 and the fifth return liquid branch channel 225 through the sub-array cold plate assembly 5; the fifth supply liquid branch channel 215 flows into the fifth return liquid branch channel 225 and the sixth return liquid branch channel 226 through the sub-array cold plate assembly 5; the sixth supply liquid branch channel 216 The coolant flows into the sixth return liquid branch channel 226 through the sub-array cold plate assembly 5; part of the coolant flows into the first return liquid main channel 41 through the first return liquid branch channel 221, the second return liquid branch channel 222, and the third return liquid branch channel 223, and finally flows out of the system; part of the coolant flows into the second return liquid main channel 42 through the fourth return liquid branch channel 224, the fifth return liquid branch channel 225, and the sixth return liquid branch channel 226, and finally flows out of the system, thereby completing the parallel supply and return of coolant for 121 sub-array cold plates.

[0049] Specifically, assuming the flow rate required for one sub-array cold plate is 'a', the total flow rate required for the entire array is 121a. The flow rate supplied through the first main liquid supply channel 31 is the sum of the flow rates supplied through the first branch liquid supply channel 211, the second branch liquid supply channel 212, and the third branch liquid supply channel 213, where the flow rates supplied through the first branch liquid supply channel 211, the second branch liquid supply channel 212, and the third branch liquid supply channel 213 are all 22a. Therefore, the flow rate of the first main liquid supply channel 31 is 66a. Similarly, the flow rate supplied through the second main liquid supply channel 32 is 55a, the flow rate supplied through the first return liquid main channel 41 is 55a, and the flow rate supplied through the second return liquid main channel 42 is 66a.

[0050] Since not all the coolant supplied by the first main supply channel 31 returns to the first main return channel 41 (part of the coolant via the third branch channel 213 returns to the second main return channel 42 via the fourth branch channel 224), meaning the upper and lower channels are not completely independent, it is necessary to adjust three of the four flow paths—the first main supply channel 31, the second main supply channel 32, the first main return channel 41, and the second main return channel 42—to achieve precise distribution of the flow rate to the 121 sub-array cold plates in the entire array. In this embodiment, by adjusting the flow rate of the first main supply channel 31 to 66a, the flow rate of the first main return channel 41 to 55a, and the flow rate of the second main return channel 42 to 66a using a liquid cooling source, the flow rate to the 121 sub-array cold plates in the entire array can be set to a.

[0051] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
