Description

Technical Field

[0001] The invention relates to the technical field of cooling chassis, in particular to a two-phase flow cooling chassis for an airborne electronic module. Background Art

[0002] Existing airborne electronic equipment mainly uses single-phase liquid cooling, which mainly includes the following two forms: one is single-phase penetrating liquid cooling, that is, the single-phase coolant directly passes through the chassis and enters the electronic module liquid cooling plate to directly take away the heat generated by the electronic module; the other is single-phase conduction liquid cooling, that is, the single-phase coolant only passes into the chassis and does not pass into the electronic module cold plate. The heat generated by the electronic module is transferred to the chassis through the air cooling plate by heat conduction, and then the coolant takes the heat out of the chassis to achieve heat dissipation of the electronic module.

[0003] Since the coolant does not directly flow into the electronic module, the single-phase conductive liquid-cooled chassis avoids the coolant leakage caused by the failure of the liquid-cooled connector or the corrosion of the liquid-cooled plate to a certain extent, reduces the risk of electrical short circuit of the airborne equipment caused by the coolant leakage, and improves the safety of the airborne equipment to a certain extent. However, for the single-phase conductive liquid-cooled chassis, the heat absorbed by the coolant when flowing through the chassis is only converted into the sensible heat of the coolant, which makes its heat dissipation capacity relatively limited. Therefore, a two-phase flow cooling chassis for airborne electronic modules is proposed to realize the two-phase heat dissipation of the electronic module. At the same time, when the temperature inside the chassis is too high, the door of the chassis can be opened and the side panels can be unfolded to accelerate the flow rate of the air inside the chassis.

[0018] As a preferred solution, in order to achieve the positioning of the side panel 7 and provide more rapid heat dissipation conditions for the chassis body 1, an explosion adjustment component 6 is arranged between the opposite sides of the base box 2 and the heat exchange box 3, and the explosion adjustment component 6 includes a threaded cylinder 601, and the two threaded cylinders 601 are respectively rotatably installed on the opposite sides of the heat exchange box 3 and the base box 2 through support blocks, and the inner surfaces of both ends of the threaded cylinder 601 are threadedly installed with threaded rods 602, and the threads of the two threaded rods 602 are set in opposite directions, and one end of the two threaded rods 602 on the same side is respectively fixedly installed on the top and bottom of one side of the side panel 7, and one side of the upper box 901 and the lower box 902 are provided with reserved holes 906 used in conjunction with the threaded rods 602, and the opposite sides of the two side panels 7 are provided with long grooves 701 used in conjunction with the guide pipe 903.

[0019] As a preferred solution, in order to achieve rapid heat dissipation of two-phase flow, a heat exchange plate 301 is fixedly installed inside the heat exchange box 3, and a number of heat pipes 302 are passed through and fixedly installed on the top of the heat exchange plate 301.

It also includes a linkage assembly 8 for use with an explosion adjustment assembly 6, which is arranged on the top and bottom of the back of the box door 5. The linkage assembly 8 includes a slide plate 801 and a gear sleeve 802. A tooth plate 803 is fixedly installed on the back of the slide plate 801. The tooth plate 803 is meshed with the gear sleeve 802. Linkage plates 804 are rotatably installed on both sides of the front of the slide plate 801.

[0023] The advantage of the second embodiment over the first embodiment is that the two side panels 7 can be easily unfolded by simply opening the box door 5, thereby providing convenient conditions for building a heat dissipation environment.

[0024] When in use, the coolant enters the bottom plate box 2 from the cold liquid inlet pipe 904, and enters the heat exchange box 3 through the guide assembly 9 set on the left. During the process, the coolant in the guide assembly 9 exchanges heat with the inside of the chassis body 1 through the guide pipe 903. After the heat exchange, the coolant passes through the heat pipe 302 and flows to the guide assembly 9 on the right, exchanges heat with the inside of the chassis body 1 again, and is finally discharged from the cold liquid outlet pipe 905. During the process, cold water enters the heat exchange box 3 from the valved inlet pipe 304, exchanges heat with the heat pipe 302, and is discharged from the valved outlet pipe 305; When the heat dissipation speed of the chassis body 1 needs to be accelerated, the two cabinet doors 5 are opened synchronously, the cabinet doors 5 drive the linkage plate 804 to move the slide plate 801 forward, the slide plate 801 drives the tooth plate 803 to move forward, the tooth plate 803 drives the gear cylinder sleeve 802 to rotate the threaded cylinder 601, and the threaded cylinder 601 drives the two threaded rods 602 to move to both sides, that is, the two threaded rods 602 push the two side plates 7 away from each other. After the cabinet door 5 rotates 90 degrees, as shown in the attached figure Figure 2 As shown, the side panel 7 is unfolded; After the heat dissipation is completed, the two cabinet doors 5 are closed synchronously to reset the slide plate 801. During the process, the tooth plate 803 drives the gear sleeve 802 to reverse the threaded cylinder 601, and the two threaded rods 602 pull the two side plates 7 closer to each other until the slide plate 801 is reset. Figure 1 Status shown.

[0025] As an extended explanation, the cover plate 303 is not provided, and air flow is used to exchange heat for the heat pipe 302. When the heat exchange efficiency needs to be improved, water is injected into the top of the heat exchange plate 301 in the heat exchange box 3. When the water temperature is high, the valve of the valved outlet pipe 305 is opened to discharge the high-temperature water, and then new cold water can be added.
