Description

Technical Field

[0001] This application relates to the field of liquid cooling technology, and in particular to a stainless steel liquid cooling plate. Background Technology

[0002] Currently, liquid cooling plate technology is a highly efficient heat dissipation method. It removes heat from heat-generating components through liquid flow and is widely used in new energy vehicles, data centers, cloud computing, and other fields. It utilizes the high thermal conductivity of liquids to cool equipment, ensuring performance and safety.

[0003] Existing liquid cooling plates are constructed by bonding two metal plates together and fixing them with bolts. One of the metal plates has a groove in the shape of a coolant channel formed by stamping. The other metal plate seals the coolant channel groove. The coolant passes through the coolant channel, and the surface of the liquid cooling plate is adjacent to or in contact with the heat source. The heat source and the coolant exchange heat, thereby achieving the liquid cooling effect.

[0004] The existing technical solutions mentioned above have the following drawbacks: Since the liquid cooling plate achieves the cooling effect through heat exchange, it requires a large coolant flow area. In the process of forming the coolant channel, the metal plate needs to be stretched and thinned, which makes the coolant channel of the metal plate soft. During the flow of the coolant, pressure is generated, and the coolant squeeze causes the two metal plates to tend to separate, which may lead to leakage. Utility Model Content

[0005] This application provides a stainless steel liquid cooling plate to enhance the stability of the liquid cooling plate and reduce the possibility of coolant leakage.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A stainless steel liquid cooling plate includes a base plate, a channel pressure plate, a fixing frame, and ribs. The base plate is bent into fixed sections along its length on both sides in a direction perpendicular to the base plate surface. The channel pressure plate is located between the fixed sections. The channel pressure plate surface is formed into a coolant channel by a stamping process. The channel pressure plate surface is in contact with the base plate surface. The fixing frame is a rectangular frame. The fixing frame is located between the fixed sections on the side of the channel pressure plate away from the base plate. Ribs are provided inside the fixing frame. The rib surfaces abut against the channel pressure plate surface away from the base plate surface.

[0008] By adopting the above technical solution, and by setting a base plate, channel pressure plate, fixing frame, and ribs, the channel pressure plate and the base plate are fitted together to form a coolant channel, allowing the coolant to flow and circulate for cooling. The fixing frame reinforces the fit between the base plate and the channel pressure plate, reducing the possibility of leakage caused by separation of the base plate and the channel pressure plate. The ribs can reinforce the channel pressure plate at the coolant channel, reducing excessive deformation of the channel pressure plate at the coolant channel, thereby reducing the possibility of coolant flow circulation rate and improving the service life of the liquid cooling plate.

[0009] Optionally, the rib plate surface is machined to form two spaced grooves, with the groove openings facing the channel pressure plate.

[0010] By adopting the above technical solution, the groove can make the rib deform to a certain extent with the deformation of the coolant channel, reducing the possibility of excessive deformation of the channel pressure plate at the coolant channel due to hard contact, and extending the service life of the liquid cooling plate.

[0011] Optionally, the coolant channel includes sixteen direct current sections, which are evenly divided into four groups. The ends of the two groups of direct current sections on both sides are connected to form four first return flow sections. The ends of the two adjacent groups of direct current sections and the four direct current sections in each group are connected to form a second return flow section. The coolant channel is M-shaped.

[0012] By adopting the above technical solution, the flow direction of the coolant can be specified through the DC section, the first return section and the second return section. Multiple independent DC sections can increase the area of ​​the liquid cooling plate adjacent to or in contact with the heat source, improve the heat exchange rate, and at the same time, the independent DC sections can achieve uniform cooling and improve the cooling effect.

[0013] Optionally, both the base plate and the channel pressure plate are made of stainless steel.

[0014] By adopting the above technical solutions, stainless steel has excellent corrosion resistance, can adapt to humid or chemical environments, has good mechanical strength and hardness, can withstand greater pressure and load, and is ductile, and will not become thinner in the stamping area due to stamping.

[0015] Optionally, an inlet and an outlet are provided on one side of the first recirculation section of the bottom plate, and both the inlet and the outlet are connected to the first recirculation section.

[0016] By adopting the above technical solution, an inlet and an outlet are provided for injecting coolant into the coolant channel for cooling, and the inlet and outlet facilitate the circulation of coolant.

[0017] Optionally, there are two inlets and two outlets. The two inlets are connected to the two first return sections on one side, and the two outlets are connected to the two first return sections on the other side.

[0018] By adopting the above technical solution and setting two inlets and two outlets, the flow rate of coolant can be accelerated, thereby improving the cooling effect of the liquid cooling plate.

[0019] Optionally, fixing holes are provided at corresponding positions on the fixing section and the side wall adjacent to the fixing frame, and bolts can be threaded into the fixing holes to fix the position of the fixing frame.

[0020] By adopting the above technical solution, bolts are inserted into the fixing holes, and the bolts are threaded to both the fixing section and the fixing frame, which can fix the fixing frame. The fixing frame reinforces the channel pressure plate and the bottom plate, reducing the possibility of the bottom plate separating from the channel pressure plate and causing leakage.

[0021] Optionally, the surface of the fixing frame is provided with mounting holes, which connect the fixing frame, the channel pressure plate and the base plate, and the mounting holes are perpendicular to the surface of the base plate.

[0022] By adopting the above technical solution, bolts can be threaded into the mounting holes, making it convenient to install the liquid cooling plate into the corresponding position and fix it.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a base plate, channel pressure plate, fixing frame, and ribs, the channel pressure plate and the base plate are fitted together to form a coolant channel, allowing the coolant to flow and circulate for cooling. The fixing frame reinforces the fit between the base plate and the channel pressure plate, reducing the possibility of leakage caused by separation of the base plate and the channel pressure plate. The ribs can reinforce the channel pressure plate at the coolant channel, reducing the possibility of excessive deformation of the channel pressure plate at the coolant channel, thereby reducing the possibility of coolant flow circulation rate and improving the service life of the liquid cooling plate.

[0025] 2. By setting up a direct flow section, a first return flow section, and a second return flow section, the flow direction of the coolant can be specified. Multiple independent direct flow sections can increase the area of ​​the liquid cooling plate adjacent to or in contact with the heat source, thereby improving the heat exchange rate. At the same time, the independent direct flow sections can achieve uniform cooling and improve the cooling effect.

[0026] 3. By using stainless steel, it has excellent corrosion resistance, can adapt to humid or chemical environments, good mechanical strength and hardness, can withstand greater pressure and load, and is ductile, so the stamping area will not become thinner due to stamping.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a stainless steel liquid cooling plate, as shown in the embodiments below. Figure 1 and Figure 2 The liquid cooling plate includes a base plate 1 and a channel pressure plate 2. Both the base plate 1 and the channel pressure plate 2 are rectangular plates made of stainless steel. The two sides of the base plate 1 are bent into fixed sections 11 in the direction perpendicular to the base plate 1 along the length direction. The fixed sections 11 and the base plate 1 form a groove. The channel pressure plate 2 is placed in the groove of the base plate 1. The surface of the channel pressure plate 2 is in contact with the surface of the base plate 1. The two ends of the channel pressure plate 2 along the length direction are flush with the two ends of the base plate 1 along the length direction. The opposite sidewall of the channel pressure plate 2 is in contact with the opposite sidewall of the fixed section 11.

[0034] Reference Figure 2 The coolant channel 21 is formed by stamping the surface of the channel pressure plate 2 against the base plate 1. In this embodiment, the coolant channel 21 includes sixteen straight sections 211 parallel to the length direction of the channel pressure plate 2. The sixteen straight sections 211 are divided into four groups of four, with each group of four straight sections 211 being parallel to each other and evenly spaced. The four groups of straight sections 211 are rectangularly distributed on the surface of the channel pressure plate 2, with each group of four straight sections 211 evenly spaced. The sixteen straight sections 211 increase the contact area between the coolant and the coolant channel 21 when it flows in the coolant channel 21, and at the same time improve the heat exchange efficiency, making the cooling effect more uniform.

[0035] Reference Figure 2Two sets of direct current sections 211 on both sides of the channel pressure plate 2 are connected to each other to form two first return flow sections 212. Two circular water inlets 3 and two water outlets 4 are spaced apart on the plate surface of the bottom plate 1 away from the channel pressure plate 2. The water inlets 3 and water outlets 4 are connected to the two plate surfaces of the bottom plate 1. The two water inlets 3 are respectively connected to the two first return flow sections 212 on one side of the channel pressure plate 2 along the length direction, and the two water outlets 4 are respectively connected to the two first return flow sections 212 on the other side of the channel pressure plate 2 along the length direction. The two water inlets 3 and the two water outlets 4 can improve the flow rate of the coolant. The four sets of DC sections 211 are connected through the second return section 213 at one end of two adjacent sets and the four DC sections 211 in one set, so that the coolant channel 21 is M-shaped as a whole, which clarifies the coolant flow direction. Water pipe joints are provided on the plate surface of the base plate 1 away from the channel pressure plate 2, and at the positions of the inlet 3 and the outlet 4. The axis of the water pipe joint is perpendicular to the plate surface of the base plate 1, and the water pipe joint is coaxial with the inlet 3 and the outlet 4.

[0036] Combination Figure 1 and Figure 2 A fixing frame 5 is also provided between the two fixing sections 11. The fixing frame 5 is located on the side of the channel pressure plate 2 away from the bottom plate 1. The fixing frame 5 is a rectangular frame structure composed of four square steel bars with openings on one side. The openings of the four square steel bars all face inward. After the fixing frame 5 is located inside the two fixing sections 11, the outer wall of the fixing frame 5 is in contact with the inner wall surface of the fixing section 11, and the surface of the fixing frame 5 is in contact with the edge of the channel pressure plate 2 away from the bottom plate 1. The fixing frame 5 is spaced apart from the coolant channel 21. The side of the fixing frame 5 that is in contact with the fixing section 11 Through-holes 51 are spaced apart on the wall and at corresponding positions of the fixed section 11. Bolts can be threaded into the fixing holes 51 to fix the position of the fixing frame 5. Several mounting holes 52 are spaced apart on the square steel adjacent to the fixing section 11 and on the square steel away from the inlet 3 of the fixing frame 5. The length direction of the mounting holes 52 is perpendicular to the surface of the base plate 1. The mounting holes 52 connect the fixing frame 5, the channel pressure plate 2 and the base plate 1. The mounting holes 52 are evenly distributed. Bolts can be inserted into the mounting holes 52 to install the liquid cooling plate to the corresponding position. Two connecting holes 53 are spaced apart on the end wall of the fixing frame 5 near the inlet 3. The two connecting holes 53 are located on both sides of the end of the fixing frame 5. The connecting holes 53 connect the inside and outside of the fixing frame 5. Bolts can be inserted into the connecting holes 53 to install the fixing frame 5 to the corresponding position.

[0037] Combination Figure 1 and Figure 3The fixing frame 5 is provided with three ribs 6. The length direction of the ribs 6 is perpendicular to the length direction of the base plate 1. The three ribs 6 are parallel to each other and spaced apart. The surface of the ribs 6 is machined with two spaced grooves along its length direction. The ends of the ribs 6 are located inside the square steel that makes up the fixing frame 5. The ribs 6 are located on the side of the channel pressure plate 2 away from the base plate 1. The surface of the ribs 6 is in contact with the surface of the coolant channel 21. The opening of the groove of the ribs 6 faces the channel pressure plate 2. The ribs 6 can always abut against the surface of the coolant channel 21. After the fixing frame 5 and the fixing section 11 are fixed with bolts, the ribs 6 reinforce the channel pressure plate 2 at the coolant channel 21, reducing the possibility of excessive deformation of the channel pressure plate 2 at the coolant channel 21.

[0038] Reference Figure 4 Two parallel and spaced support pipes 7 are provided on the surface of the base plate 1 away from the channel pressure plate 2, and an mounting plate 8 is located between the support pipes 7 and the water inlet 3. The length direction of the support pipes 7 is parallel to the length direction of the base plate 1, and the length direction of the mounting plate 8 is parallel to the length direction of the base plate 1. Several mounting holes 52 are evenly spaced on the edge of the rib plate 6 near the water inlet 3. The mounting holes 52 are spaced apart from the coolant channel 21. The mounting holes 52 connect the rib plate 6, the channel pressure plate 2, the base plate 1 and the mounting plate 8. Bolts can be inserted into the mounting holes 52 to facilitate the installation and fixing of the liquid cooling plate in the corresponding position.
