DETAILED DESCRIPTION

[0034] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0035] Embodiment 1

[0036] This embodiment provides a technical solution: an evaporative two-phase liquid cooling radiator, such as Figure 1-Figure 8As shown, it includes a shell component 1 and a heat-conducting structure 2. The shell component 1 includes a cooling shell 101, a heat-collecting shell 102 and a contact shell 103. The cooling shell 101, the heat-collecting shell 102 and the contact shell 103 are welded in sequence from top to bottom. The bottom of the contact shell 103 directly contacts the component that needs heat dissipation and helps it to dissipate heat. A heat-conducting cavity 3 is opened in the contact shell 103. The heat-conducting structure 2 is arranged in the heat-conducting cavity 3. The heat-conducting structure 2 includes a plurality of heat-conducting bottom columns 201 and a plurality of heat-conducting powder columns 202. The plurality of heat-conducting bottom columns 201 are fixedly installed on the inner wall of the heat-conducting cavity 3. The plurality of heat-conducting powder columns 202 are installed at the bottom of the heat-collecting shell 102 and are arranged above the heat-conducting bottom columns 201. After the heat enters the heat-conducting cavity 3 in the contact shell 103 The heat-conducting bottom column 201 can quickly conduct heat and help the components to cool down quickly. The heat-conducting cavity 3 and the heat-collecting cavity 5 are both in a semi-vacuum state. The heat-conducting cavity 3 is filled with cooling water. When the cooling shell 101, the heat-collecting shell 102 and the contact shell 103 are produced by the welding process, the heat-conducting cavity 3 and the heat-collecting cavity 5 should be processed into a semi-vacuum state before welding and sealing. The cooling water should account for about half of the volume of the heat-conducting cavity 3. Part of the heat can be quickly absorbed by the cooling water. Since the semi-vacuum state can help water boil quickly, the cooling water can evaporate and generate steam when absorbing heat. Part of the steam rises and directly contacts the thermal powder column 202. The thermal powder column 202 can quickly absorb heat and cause part of the steam to liquefy into water again and drip downward.

[0037] In the specific implementation, such as Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, a floating heat-conducting assembly 4 for quickly conducting heat is arranged in the heat-collecting shell 102 and the cooling shell 101. The floating heat-conducting assembly 4 includes a heat-conducting block 401, an upper baffle 402 and a lower baffle 403. A heat-collecting cavity 5 is provided on the heat-collecting shell 102. A cooling cavity 6 connected to the heat-collecting cavity 5 is provided at the bottom of the cooling shell 101. A limiting frame 7 with a through opening in the middle is installed at the bottom of the inner wall of the cooling cavity 6. The heat-conducting block 401 is stuck in the through opening. This can ensure that the heat-conducting block 401 can block the opening and create a sealed environment for the heat-collecting cavity 5. The upper baffle 402 and the lower baffle 403 are respectively installed on the top and bottom of the heat-conducting block 401. The upper baffle 402 and the lower baffle 403 are respectively located in the cooling cavity 6 and the heat-collecting cavity 5. The heat-conducting block 401 can be limited by the upper baffle 402 and the lower baffle 403. Multiple air pipes 8 are installed on both sides of the heat-collecting shell 102. The air pipes 8 can conveniently guide the heat-conducting The heat in the heat chamber 3, one end of the air pipe 8 is located on both sides of the top of the heat conductive block 401 and the other end of the air pipe 8 is connected to the heat conductive chamber 3, so the heat can be easily transferred to the top of the heat conductive block 401, and a reflux port 9 is opened between the center position of the inner wall of the heat collecting chamber 5 and the heat conductive chamber 3. The reflux port 9 can ensure that the liquefied water in the heat collecting chamber 5 can flow back into the heat conductive chamber 3. When evaporation occurs in the heat conductive chamber 3, the steam can be blown from the heat conductive chamber 3 to the top of the heat conductive block 401 through each air pipe 8. The upper part of the heat conductive block 401 can be quickly and concentratedly heated, and the pressure in the heat collecting chamber 5 can be increased rapidly, so that the heat conductive block 401 can be pushed to move upward, thereby preventing the heat collecting shell 102 from deforming, and the upper part of the heat conductive block 401 can be moved to the cooling chamber 6. Since the heat is concentrated on the upper part of the heat conductive block 401, the heat dissipation efficiency can be greatly increased and the heat collecting chamber 5 can be placed in a relatively low temperature environment.

[0038] In the specific implementation, such as Figure 1 and Figure 2 As shown, two installation openings are provided on the top of the cooling chamber 6, and a liquid inlet pipe 10 and a liquid discharge pipe 11 are respectively installed in the two installation openings. Cold water can be conveniently introduced into the cooling chamber 6 through the liquid inlet pipe 10, so that the heat can be quickly dissipated with the upper part of the floating heat-conducting component 4. The water in the cooling chamber 6 can be conveniently discharged through the liquid discharge pipe 11 to ensure the pressure balance in the cooling chamber 6.

[0039] In a specific implementation, a heat transfer one-way valve 13 is installed on the gas supply pipe 8, with a flow path from the heat transfer chamber 3 to the heat collection chamber 5. Therefore, the steam generated in the heat transfer chamber 3 can flow from the heat transfer chamber 3 into the heat collection chamber 5, and the steam in the heat collection chamber 5 cannot flow back into the heat transfer chamber 3. A reflux one-way valve 14 is installed in the reflux port 9, with a flow path from the heat collection chamber 5 to the heat transfer chamber 3. Therefore, the cooling water in the heat transfer chamber 3 cannot flow into the heat collection chamber 5 through the reflux port 9 under any conditions.

[0040] In the specific implementation, such as Figure 4 and Figure 5 As shown, a plurality of elastic connection components 12 are arranged between the lower baffle plate 403 and the limit frame 7. The elastic connection components 12 can ensure the elastic connection between the lower baffle plate 403 and the limit frame 7, so that the floating heat-conducting component 4 can be arranged more stably and will not affect the up and down movement of the heat-conducting block 401. The elastic connection components 12 include a positioning rod 1201, a connecting rod 1202 and a sealing sheet 1203. The positioning rod 1201 is installed at the bottom of the edge of the limit frame 7, and the connecting rod 1202 is installed at the top of the edge of the lower baffle plate 403. A connecting cavity is opened in the positioning rod 1201, and the connecting rod 1202 is inserted into the connecting cavity. The sealing sheet 1203 is welded to the top of the connecting rod 1202 and is clamped in the connecting cavity. In the above description, when the floating heat-conducting component 4 is working, the heat-conducting block 401 moves up, and at the same time, the sealing sheet 1203 and the connecting rod 1202 can move along the connecting cavity inside the positioning rod 1201, thereby ensuring the stable movement of the heat-conducting block 401.

[0041] Furthermore, the elastic connection component 12 also includes a limit spring 1204, which is installed between the sealing sheet 1203 and the inner wall of the connecting cavity. In the above description, when the floating heat-conducting component 4 is working, the heat-conducting block 401 moves up, and at the same time, the sealing sheet 1203 and the connecting rod 1202 can move along the connecting cavity inside the positioning rod 1201. The sealing sheet 1203 can adaptively squeeze the limit spring 1204. The limit spring 1204 can prevent the heat-conducting block 401 from moving up too fast and causing the upper baffle 402 to collide with the inner wall of the cooling cavity 6, and the elastic force of the limit spring 1204 can ensure that the heat-conducting block 401 is quickly reset after the heat dissipation is completed.

[0042] In the specific implementation, such as Figure 6 As shown, a microchannel plate 15 composed of multiple metal sheets is installed on the inner wall of the heat collecting chamber 5. The microchannel plate 15 can quickly absorb the heat of the steam entering the bottom of the heat collecting chamber 5 and liquefy the steam, thereby further improving the heat dissipation effect and safety. The microchannel plate 15 is located below the lower baffle 403, and the reflow port 9 extends to penetrate the microchannel plate 15. The reflow port 9 is located at the center of the microchannel plate 15. The microchannel plate 15 is designed to be concave toward the center to have a diversion effect, so the microchannel plate 15 can help the cooling water to quickly reflux.

[0043] When the present embodiment is in use, the contact shell 103 is arranged in contact with the element that needs heat dissipation. After the element is heated up, the bottom of the contact shell 103 directly contacts the element that needs heat dissipation and helps it to dissipate heat. At the same time, after the heat enters the heat-conducting cavity 3 in the contact shell 103, the heat-conducting bottom column 201 can quickly conduct the heat and help the element to cool down quickly. Part of the heat can be quickly absorbed by the cooling water. Since the semi-vacuum state can help the water to boil quickly, the cooling water can evaporate and generate steam when absorbing heat. Part of the steam rises and directly contacts the heat-conducting powder column 202. The heat-conducting powder column 202 can quickly absorb heat and cause part of the steam to liquefy into water again and drip downward. The remaining steam can pass through the heat-conducting one-way valve 13 and be blown from the heat-conducting cavity 3 to the top of the heat-conducting block 401 through each gas supply pipe 8. The upper part of the heat-conducting block 401 can be quickly and concentratedly heated. At the same time, the pressure in the heat collection cavity 5 can be quickly increased, so that the heat-conducting block 401 can be pushed to move upward. When the heat conducting block 401 moves upward, the sealing sheet 1203 and the connecting rod 1202 can move along the connecting cavity inside the positioning rod 1201, and the sealing sheet 1203 can adaptively squeeze the limit spring 1204, so as to prevent the heat collecting shell 102 from being deformed. At the same time, the upper part of the heat conducting block 401 can move into the cooling cavity 6. Since the heat is concentrated in the upper part of the heat conducting block 401, the heat dissipation efficiency can be greatly increased and the heat collecting cavity 5 can be placed in a relatively low temperature environment. External water can be injected into the cooling cavity 6 through the liquid inlet to quickly dissipate the heat of the upper part of the heat conducting block 401. After the heat dissipation is completed, the floating heat conducting component 4 can be quickly reset under the elastic force of the limit spring 1204. At the same time, during the heat dissipation process, part of the steam can be liquefied again in the heat conducting cavity 3, and part of the steam can be liquefied in the heat collecting cavity 5. After cooling, the cooling water can pass through the reflux check valve 14 and flow back into the heat conducting cavity 3 under the action of the negative pressure in the heat conducting cavity 3.

[0044] Embodiment 2

[0045] This embodiment is further optimized on the basis of the above embodiment, and the same parts as the above technical solution will not be repeated here. Fig. 9 and Fig.10 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0046] In the specific implementation, such as Fig. 9 As shown, a pump body 16 is arranged above the cooling shell 101, and one end of the pump body 16 is connected to the liquid inlet pipe 10. The pump body 16 can conveniently pump external water into the cooling chamber 6 to quickly dissipate heat for the heat collection shell 102 and the floating heat conductive component 4.

[0047] In the specific implementation, such as Fig.10As shown, a trigger assembly 17 for automatically triggering the pump body 16 is provided on the top of the inner wall of the cooling chamber 6, and the trigger assembly 17 includes a push switch 1701, a mounting spring 1702 and a trigger rod 1703. A trigger groove 18 is provided on the inner wall of the cooling chamber 6, and the push switch 1701 is installed on the inner wall of the trigger groove 18 by means of the mounting spring 1702. The mounting spring 1702 can provide a movable space for the push switch 1701, and a trigger hole 19 is provided between the trigger groove 18 and the inner wall of the cooling chamber 6. The trigger rod 1703 is installed on the top of one side of the upper baffle 402 and corresponds to the trigger hole 19. The trigger rod 1703 and A certain distance is left between the trigger holes 19, and the push switch 1701 is connected to the pump body 16 through an electric wire. The trigger rod 1703 can move upward with the floating heat-conducting component 4 when the floating heat-conducting component 4 moves upward, and then the trigger rod 1703 can enter the trigger hole 19 and contact with the push switch 1701 to trigger the pump body 16. The pump body 16 can automatically pump external water into the cooling chamber 6, thereby helping the floating heat-conducting component 4 to dissipate heat quickly, and after the heat dissipation is completed, the trigger rod 1703 is reset along with the floating heat-conducting component 4, and the push switch 1701 is stopped after being reset, thereby automatically closing the pump body 16.

[0048] Furthermore, a protective sheet 20 is provided in the trigger groove 18 of the trigger assembly 17. The protective sheet 20 is arranged between the push switch 1701 and the trigger hole 19. The protective sheet 20 can prevent steam and moisture from entering the trigger groove 18, thereby protecting the push switch 1701.

[0049] When this embodiment is in use, when the floating heat-conducting component 4 floats upward in the above embodiment, the trigger rod 1703 can enter the trigger hole 19 and push the protective sheet 20 to squeeze the push switch 1701 to trigger the pump body 16. The pump body 16 can automatically pump external water into the cooling chamber 6, thereby helping the floating heat-conducting component 4 to dissipate heat quickly. After the heat dissipation is completed, the trigger rod 1703 is reset along with the floating heat-conducting component 4 and stops pressing the push switch 1701 after being reset, thereby automatically closing the pump body 16.
