Description

Technical Field

[0001] This utility model relates to the field of radiator equipment technology, specifically to a flow channel structure for a water-cooled plate radiator. Background Technology

[0002] Today, the performance of electronic and industrial equipment is constantly improving, and the heat generated during their operation is also increasing dramatically. In data centers, the high-density deployment of servers causes CPUs, GPUs, and other chips to release a large amount of heat during operation, requiring the use of heat sinks for heat dissipation. Water cooling technology has gradually gained widespread attention due to its high heat dissipation efficiency. Some heat sinks have relatively simple flow channel designs, usually straight channels or single curved channels. This results in a short flow path for the coolant in the flow channel, limited contact time and area with the heat sink, and low heat exchange efficiency. Therefore, a flow channel structure for a water-cooled plate heat sink is proposed.

[0003] Chinese Utility Model Patent Publication No. CN 209806287 U discloses a plate-type water-cooled radiator. This plate-type water-cooled radiator uses a plastic cover plate formed by overmolding to fix it to a metal substrate, which has a good sealing effect, avoids water leakage, avoids damage to components, and ensures the heat dissipation effect of the radiator. The use of plastic cover plate formed by overmolding to seal the radiator to the metal substrate eliminates the need for welding and other fixing methods, reducing production costs. However, this plate-type water-cooled radiator has a short water cooling channel length, a small contact area between the coolant and the metal substrate, low heat exchange efficiency, and poor heat dissipation effect. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a flow channel structure for a water-cooled plate radiator, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a flow channel structure of a water-cooled plate radiator, including a lower plate body, an upper plate body is provided at the upper end of the lower plate body, a fixing column is fixedly connected at the lower end of the upper plate body, and a fixing joint is provided at the front end of the lower plate body and the upper plate body.

[0006] The lower plate includes a heat sink, a first flow channel, a second flow channel, an exchange plate, a limiting groove, and an alignment groove. The upper end of the heat sink has a first flow channel and a second flow channel. An exchange plate is fixedly connected inside the first flow channel and the second flow channel. The front end of the heat sink has a limiting groove, and the upper end of the heat sink has an alignment groove.

[0007] Preferably, the upper plate and the lower plate have symmetrical and identical structures, which ensures the consistency of the flow channel structure and is conducive to the uniform and stable flow of coolant throughout the radiator.

[0008] With the above technical solution, the upper and lower parts of the radiator can be manufactured and assembled using the same process and procedures.

[0009] Preferably, the first flow channel and the second flow channel are interconnected, both of which have an "S" shaped structure and are perpendicular to each other.

[0010] Through the above technical solution, the "S"-shaped structure extends the flow path of the coolant in the channel, increases the contact time and area between the coolant and the heat sink, thereby improving the heat exchange efficiency. The length of channel one is longer than that of channel two, thus dividing the radiator into two areas. The coolant flows in from channel one and flows out from channel two. The area through which channel one flows has a better heat dissipation effect and can dissipate heat for electrical components that generate more heat. Channel two is shorter, and the coolant flows through it for a shorter time. This reasonable allocation of heat dissipation area makes it more flexible in use.

[0011] Preferably, the width of the first flow channel is 19mm to 20mm, and the depth of the first flow channel is 3mm to 3.5mm.

[0012] Through the above technical solutions, a wider flow channel can accommodate more coolant and increase heat capacity, while an appropriate depth ensures that the coolant has sufficient contact area with the heat sink. The appropriate design of the flow channel width and depth can ensure that the coolant has sufficient flow rate and velocity.

[0013] Preferably, the width of the exchange plate is 1.8mm to 2mm, and the two exchange plates are arranged in parallel and evenly in the non-bent portions of the flow channel groove one and the flow channel groove two.

[0014] Through the above technical solution, the arrangement of the heat exchange plates disrupts the flow state of the coolant in the flow channel, causing the coolant to generate more turbulence and vortices, which enhances the heat exchange process between the coolant and the heat sink. The parallel arrangement does not excessively hinder the flow of coolant, but effectively increases the opportunity for heat exchange, improves heat dissipation efficiency, and allows heat to be transferred more quickly from the heat sink to the coolant, thereby improving the overall heat dissipation capacity of the radiator.

[0015] Preferably, the fixing post is adapted to the alignment groove.

[0016] Through the above technical solution, the matching design of the fixing column and the alignment groove can achieve rapid and accurate positioning when assembling the upper and lower plates, which improves assembly efficiency and reduces errors and time costs in the assembly process.

[0017] Preferably, the fixed joint is plugged into the lower plate and the upper plate, and both the lower plate and the upper plate are made of aluminum alloy.

[0018] The above technical solution facilitates the connection and disassembly of coolant pipes and radiators through plug-in connection, simplifies the installation and maintenance process, and reduces the difficulty and cost of operation.

[0019] Compared with the prior art, this utility model provides a flow channel structure for a water-cooled plate radiator, which has the following beneficial effects:

[0020] 1. The flow channel structure of this water-cooled plate radiator, through a unique flow channel design, has flow channel one and flow channel two interconnected and in an "S" shape and perpendicular to each other, which greatly extends the flow path of the coolant, increases the contact time and area between the coolant and the heat sink, and significantly improves the heat exchange efficiency. In addition, the longer flow channel one can provide better heat dissipation for electrical components with higher heat generation, while flow channel two is adapted to areas with lower heat generation, realizing flexible and precise heat dissipation area allocation, which can effectively cope with complex heat source layout and ensure uniform and efficient overall heat dissipation effect;

[0021] 2. The flow channel structure of this water-cooled plate radiator has a suitable width and depth, which can not only accommodate sufficient coolant to increase heat capacity, but also ensure sufficient contact area between coolant and heat sink. The exchange plates set in the flow channel effectively disrupt the flow state of coolant, promote the formation of turbulence and vortex, greatly enhance the heat exchange process between coolant and heat sink. Without affecting the normal flow of coolant, it significantly increases the heat exchange opportunity, so that heat can be transferred from heat sink to coolant more quickly, thereby comprehensively improving the heat dissipation capacity of the radiator.

[0022] 3. The flow channel structure of this water-cooled plate radiator, along with the matching design of the fixing column and the alignment groove, enables rapid and accurate positioning of the upper and lower plates, reducing assembly errors and time costs. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-5 As shown, the flow channel structure of a water-cooled plate radiator provided by this utility model includes a lower plate 1, an upper plate 2 is provided at the upper end of the lower plate 1, a fixing post 3 is fixedly connected to the lower end of the upper plate 2, and a fixing joint 4 is provided at the front end of the lower plate 1 and the upper plate 2.

[0031] The lower plate 1 includes a heat sink 101, a first flow channel 102, a second flow channel 103, an exchange plate 104, a limiting groove 105, and an alignment groove 106. The heat sink 101 has a first flow channel 102 and a second flow channel 103 at its upper end. The exchange plate 104 is fixedly connected inside the first flow channel 102 and the second flow channel 103. The front end of the heat sink 101 has a limiting groove 105, and the upper end of the heat sink 101 has an alignment groove 106.

[0032] Specifically, the upper plate 2 and the lower plate 1 have symmetrical and identical structures, ensuring consistency in the flow channel structure and facilitating uniform and stable flow of coolant throughout the radiator. An advantage is that the upper and lower parts of the radiator can be manufactured and assembled using the same processes and procedures.

[0033] Specifically, flow channel one 102 and flow channel two 103 are interconnected, and both flow channel one 102 and flow channel two 103 have an "S"-shaped structure, and are perpendicular to each other. The advantage is that the "S"-shaped structure extends the flow path of the coolant within the flow channel, increasing the contact time and area between the coolant and the heat sink 101, thereby improving heat exchange efficiency. Flow channel one 102 is longer than flow channel two 103, thus dividing the radiator into two areas. Coolant flows into flow channel one 102 and out of flow channel two 103. The area through which flow channel one 102 flows has better heat dissipation, providing cooling for electrical components that generate more heat. Flow channel two 103 is shorter, resulting in a shorter coolant flow time, allowing for a more flexible allocation of heat dissipation areas.

[0034] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the width of the flow channel 102 is 19mm to 20mm, and the depth of the flow channel 102 is 3mm to 3.5mm. The advantage is that the wider flow channel can hold more coolant, increasing the heat capacity, while the appropriate depth ensures that the coolant has sufficient contact area with the heat sink 101. The appropriate design of the flow channel width and depth can ensure that the coolant has sufficient flow rate and velocity.

[0036] Specifically, the exchange plates 104 have a width of 1.8mm to 2mm, and two exchange plates 104 are arranged parallel and evenly in the non-bendable portions of the first flow channel 102 and the second flow channel 103. The advantage is that the arrangement of the exchange plates 104 disrupts the flow state of the coolant within the flow channels, causing more turbulence and vortices in the coolant, thus enhancing the heat exchange process between the coolant and the heat sink 101. The parallel arrangement does not excessively obstruct the flow of the coolant, while effectively increasing the opportunity for heat exchange, improving heat dissipation efficiency, and allowing heat to be transferred more quickly from the heat sink 101 to the coolant, thereby enhancing the overall heat dissipation capacity of the radiator.

[0037] Specifically, the fixing post 3 is adapted to the alignment groove 106. The advantage is that when assembling the upper plate 2 and the lower plate 1, the adaptation design of the fixing post 3 and the alignment groove 106 can achieve fast and accurate positioning, improve assembly efficiency, and reduce errors and time costs in the assembly process.

[0038] Specifically, the fixed connector 4 is plug-in connected to the lower plate 1 and the upper plate 2, both of which are made of aluminum alloy. The advantage is that the plug-in connection of the fixed connector 4 facilitates the connection and disassembly of the coolant piping and the radiator, simplifies the installation and maintenance process, and reduces operational difficulty and cost.

[0039] Working principle: When assembling the upper plate 2 and the lower plate 1, the fixing post 3 is aligned and inserted into the alignment groove 106. The fixing joint 4 is used to combine and fix the upper plate 2 and the lower plate 1. Then, the upper plate 2 and the lower plate 1 are welded together using brazing. The assembly efficiency is high. When in use, the radiator is fixed to the heat source. The first flow channel 102 contacts the part with high heat generation, and the second flow channel 103 contacts the part with low heat generation. The limiting groove 105 can be used to visually distinguish the areas. The coolant flows in from the first flow channel 102 and flows out from the second flow channel 103. The flow channel 102 provides better heat dissipation in the area through which the coolant flows, and can dissipate heat for electrical components that generate more heat. The flow channel 2 103 is shorter in length, resulting in a shorter coolant flow time. It can reasonably allocate the heat dissipation area and is more flexible in use. The exchange plates 104 set in the flow channel effectively disrupt the coolant flow state, promote the formation of turbulence and vortex, enhance the heat exchange process between the coolant and the heat sink 101, increase the heat exchange opportunity, and enable heat to be transferred from the heat sink 101 to the coolant more quickly, thereby comprehensively improving the heat dissipation capacity of the radiator.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
