Description

TECHNICAL FIELD

[0001] The utility model belongs to the cold plate technical field, concretely relates to a heat dissipation cold plate. BACKGROUND

[0002] The heat dissipation cold plate, also known as a cold plate radiator or liquid cooling plate, is a kind of liquid cooling radiator, through the internal flow channel design, so that the cooling liquid (such as water or other liquid) flows in it, and takes away the heat generated by the equipment.

[0003] The water-cooled heat dissipation plate provided in the prior Chinese utility model patent (publication number: CN209882421U) has a through hole directly in the metal plate body, and the through holes are sequentially staggered and communicated to form a continuous S-shaped cooling channel. When in use, cooling liquid flows in the cooling channel, and the heat absorbed by the metal plate body can be directly transferred to the cooling liquid to take away. The traditional copper pipe is removed, and the copper pipe loosening problem does not occur, which can ensure the stability of the heat dissipation performance.

[0004] However, in the prior art, when the pressure of the liquid is lower than its saturated vapor pressure, the liquid will vaporize and form bubbles, which is called cavitation. Cavitation may cause the pressure in the local area to decrease, thereby causing cavitation. At this time, the bubbles will occupy the space of the flow channel, reduce the contact area of the cooling liquid and the heat dissipation plate, and thus reduce the heat transfer efficiency, resulting in poor heat dissipation effect.

[0005] Therefore, the present application provides a heat dissipation cold plate to solve the above problems. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing a heat dissipation cold plate to solve the cavitation phenomenon in the prior art, which produces bubbles that occupy the space of the flow channel, reduce the contact area of the cooling liquid and the heat dissipation plate, and thus reduce the heat transfer efficiency, resulting in poor heat dissipation effect.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a heat dissipation cold plate, comprising a cooling assembly and a cover plate, the cooling assembly top surface is provided with the cover plate, the cooling assembly side wall is provided with the liquid inlet pipe symmetrically, the cooling assembly is installed with the liquid outlet pipe piece in the middle of one side of the liquid inlet pipe, and the cooling assembly inner cavity is uniformly distributed with a plurality of bubble removal assemblies.

[0008] The bubble removal assembly comprises a connecting frame, a connecting hole is formed in the connecting frame, a beam current sleeve is installed in the inner cavity of the connecting hole, a positioning frame is installed on the inner cavity side wall of the connecting frame, and a plurality of division rods are uniformly arranged on the inner wall of the positioning frame.

[0009] Preferably: the cooling assembly includes a mounting frame, the inner cavity of the mounting frame is staggered with partition plates, the top surface of the mounting frame is bolted with a cover plate, a connecting frame is installed between adjacent partition plates, and a connecting frame is installed between the inner wall of the mounting frame and the partition plate.

[0010] Preferably, liquid inlet pipes are symmetrically installed on one side wall of the installation frame, and the liquid outlet pipe is located between the two liquid inlet pipes.

[0011] Preferably, the liquid outlet pipe member includes a liquid outlet pipe body, the liquid outlet pipe body is installed on the side wall of the installation frame, the liquid outlet pipe body is connected to the inner cavity of the installation frame, and an isolation plate is installed on the inner wall of the liquid outlet pipe body.

[0012] Preferably: a diverter assembly is installed between the partition plate in the middle of the inner cavity of the installation frame and the installation frame, the diverter assembly includes a fixed frame, a fixed frame is installed between the partition plate in the middle of the inner cavity of the installation frame and the installation frame, and a diverter plate is installed in the middle of the bottom surface of the inner cavity of the fixed frame.

[0013] Preferably, the inner cavity of the diverter plate is connected to an isolation plate, and the side wall of the diverter plate is connected to the isolation plate.

[0014] Preferably, guide blocks are respectively installed on both sides of the fixing frame, and the guide blocks are wedge-shaped.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model sets a debubbling component in a heat dissipation cold plate. When the device is in use, the various structures in the above components cooperate with each other to achieve the effect of debubbling the coolant flowing in the installation frame, thereby improving the use efficiency of the device and solving the problem of cavitation in the prior art during use. The bubbles generated by the cavitation will occupy the space of the flow channel, reduce the contact area between the coolant and the heat dissipation plate, thereby reducing the heat transfer efficiency and causing the heat dissipation effect to deteriorate.

[0017] 2. The utility model arranges a liquid inlet pipe, a liquid outlet pipe and a diversion component in a heat dissipation cold plate. During the use of the device, the structures in the above components cooperate with each other to change the traditional "S"-shaped flow mode to inlet at both ends and outlet in the middle, thereby improving the overall cooling effect of the device and solving the problem that the traditional unidirectional "S"-shaped flow mode will cause the coolant at the end of the flow to have higher heat than the coolant at the front end, thereby having a lower cooling effect and causing uneven heat dissipation effect of the device.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 1-6 As shown, the utility model provides a heat dissipation cold plate, including a cooling component 1 and a cover plate 2. The cover plate 2 is provided on the top surface of the cooling component 1, and liquid inlet pipes 3 are symmetrically provided on the side walls of the cooling component 1. A liquid outlet pipe 4 is installed in the middle of one side of the cooling component 1 where the liquid inlet pipe 3 is installed, and a plurality of defoaming components 5 are evenly distributed in the inner cavity of the cooling component 1.

[0027] The debubble assembly 5 includes a connecting frame 501, a connecting hole 503 is formed on the connecting frame 501, a beam sleeve 502 is installed in the inner cavity of the connecting hole 503, a positioning frame 504 is installed on the inner cavity side wall of the connecting frame 501, and a plurality of dividing rods 505 are evenly arranged on the inner wall of the positioning frame 504;

[0028] The diameter of the inner cavity of the beam sleeve 502 gradually decreases along the flow direction of the coolant. According to A1 v1 = A2v2 (where A1 and A2 are the areas of different cross-sections of the pipe, and v1 and v2 are the average flow velocities on the corresponding cross-sections), it can be concluded that as the cross-section of the beam sleeve 502 gradually decreases, the outflow velocity of the coolant will increase.

[0029] The cooling assembly 1 includes a mounting frame 101, wherein the inner cavity of the mounting frame 101 is staggeredly provided with partition plates 102, the top surface of the mounting frame 101 is bolted with a cover plate 2, a connecting frame 501 is installed between adjacent partition plates 102, and a connecting frame 501 is installed between the inner wall of the mounting frame 101 and the partition plates 102;

[0030] In this embodiment, during use of the device, the flowing coolant will pass through the split rod 505 and the beam sleeve 502 in sequence. When passing through the split rod 505, the coolant will be split and impact with the split rod 505 to perform a bubble removal operation.

[0031] Subsequently, under the action of the beam sleeve 502, the diameter of the pipe in which the coolant can flow will become smaller. According to the formula A1v1=A2v2 (where A1 and A2 are the areas of different cross-sections of the pipe, and v1 and v2 are the average flow velocities on the corresponding cross-sections), it can be concluded that as the cross-section of the beam sleeve 502 gradually decreases, the outflow speed of the coolant will increase. The coolant ejected at high speed from the beam sleeve 502 will collide with the mounting frame 101 and the partition plate 102, further enhancing the defoaming effect.

[0032] In a further embodiment, referring to Figure 1-Figure 5 , a liquid inlet pipe 3 is symmetrically installed on one side wall of the installation frame 101, and the liquid outlet pipe 4 is located between the two liquid inlet pipes 3;

[0033] The liquid outlet pipe 4 includes a liquid outlet pipe body 401. The liquid outlet pipe body 401 is installed on the side wall of the installation frame 101. The liquid outlet pipe body 401 is connected to the inner cavity of the installation frame 101. An isolation plate 402 is installed on the inner wall of the liquid outlet pipe body 401.

[0034] A flow diversion assembly 6 is installed between the partition plate 102 in the middle of the inner cavity of the installation frame 101 and the installation frame 101. The flow diversion assembly 6 includes a fixing frame 601. The fixing frame 601 is installed between the partition plate 102 in the middle of the inner cavity of the installation frame 101 and the installation frame 101. A flow diversion plate 602 is installed in the middle of the bottom surface of the inner cavity of the fixing frame 601.

[0035] The design of the diverter plate 602 and the isolation plate 402 prevents the coolants on both sides from impacting each other, which would cause excessive local pressure in the inner cavity of the mounting frame 101 and damage the cooling assembly 1, thereby reducing the service life of the device.

[0036] The inner cavity of the diverter plate 602 is connected to the isolation plate 402, and the side wall of the diverter plate 602 is connected to the isolation plate 402;

[0037] Guide blocks 7 are installed on both sides of the fixed frame 601. The guide blocks 7 are wedge-shaped.

[0038] The guide block 7 enhances the strength of the cooling liquid gathering place, and prolongs the service life of the device.

[0039] In the embodiment, the cooling liquid is injected from the two liquid inlet pipes 3 to the inner cavity of the mounting frame 101 during use of the device, sequentially flows through the path surrounded by the partition plates 102, and finally flows to the position of the fixing frame 601.

[0040] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
