Description

Technical Field

[0001] The utility model belongs to the technical field of liquid cooling plates, and particularly relates to an aluminum alloy liquid cooling plate with high heat capacity. Background Technique

[0002] A liquid cooling plate is a heat exchange device that indirectly transfers the heat of a heat-generating device to a cooling liquid enclosed in a circulating pipeline through a cold plate (usually made of aluminum alloy with high heat capacity), and then uses the cooling liquid to take away the heat. Liquid cooling plates are widely used in many fields, such as new energy vehicles, data centers, wind power converters, photovoltaic inverters, etc.

[0003] In the Chinese patent with the publication number CN221466659U, a liquid cooling plate is mentioned, which includes a base plate and a flow channel plate. The base plate is provided with a liquid inlet pipe and a liquid outlet pipe, and the flow channel plate is provided with a number of guide posts and guide strips. The base plate, the flow channel plate, the guide posts and the guide strips jointly define a cooling flow channel. The flow channel plate includes a liquid inlet area and a liquid outlet area that are symmetrically arranged and communicated with each other. The liquid inlet area includes a number of groups of guide post groups longitudinally and parallelly distributed, and a guide strip group is arranged between adjacent guide post groups. Each group of guide post groups includes a number of guide posts horizontally and transversely distributed. By the orderly distribution of multiple groups of guide post groups and guide strip groups in the liquid inlet area and the liquid outlet area, the utility model increases the flow width of the liquid inlet area and the liquid outlet area, enables the cooling liquid to flow more evenly and smoothly in the liquid inlet area and the liquid outlet area, and thus makes the overall liquid cooling plate have better temperature uniformity;

[0004] Although the above-mentioned device expands the liquid inlet area and the liquid outlet area to make the cooling liquid flow more smoothly, the liquid cooling plate is divided into an advanced liquid inlet area and a rear liquid outlet area by an internal transition flow channel, so that when the cold liquid enters, the temperature of the advanced liquid inlet area will decrease first and then the temperature of the rear liquid outlet area will decrease, resulting in uneven cooling.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Referring to Figures 1-7 As shown, the present utility model provides an aluminum alloy liquid cooling plate with high heat capacity, which includes a cooling plate 1 and an intersecting transition component 13. The cooling plate 1 is provided with a liquid cooling groove 2 penetrating up and down. Inside the liquid cooling groove 2, symmetrically arranged partition plates 6 and 7 are embedded. An intersecting transition component 13 is arranged between the partition plate 6 and the partition plate 7. Both the upper and lower ends of the cooling plate 1 are bolted with symmetrically arranged upper and lower cover plate components 12;

[0030] The intersecting transition component 13 includes an intersecting block 132 and diversion blocks 135 fixedly connected to both sides of the intersecting block 132. The intersecting block 132 is used for intersecting and diverting the coolant, and the diversion blocks 135 are used to expand the diversion ports of the intersecting block 132;

[0031] The cover plate component 12 includes a cover plate 121 and longitudinal diversion strips 122. The longitudinal diversion strips 122 are fixedly connected to the end face of the cover plate 121 close to the cooling plate 1. The longitudinal diversion strips 122 are used for gently dispersing the coolant.

[0032] In a further embodiment, the partition plate 6 and the partition plate 7 separate the liquid cooling groove 2. Above the partition plate 6 and the partition plate 7, together with the liquid cooling groove 2, they form an inlet area 8. Below the partition plate 6 and the partition plate 7, together with the liquid cooling groove 2, they form an outlet area 9; There is a sealing member when the cover plate 121 is connected to the cooling plate 1.

[0033] In this embodiment, only the externally cooled liquid enters the inlet area 8, and the outlet area 9 receives the coolant that has absorbed a certain amount of heat from inside the inlet area 8.

[0034] In a further embodiment, both the upper and lower ends of the partition plate 6 and the partition plate 7 are provided with a plurality of symmetrically arranged upper and lower transverse diversion strips 3 and inclined diversion strips 4. The transverse diversion strips 3 and the inclined diversion strips 4 are evenly arranged. The inclined diversion strips 4 are located on both sides of the intersecting transition component 13. The spaces between the transverse diversion strips 3 form liquid cooling channels 5. The longitudinal diversion strips 122 are perpendicular to the transverse diversion strips 3, and the longitudinal diversion strips 122 are arranged inside the liquid cooling channels 5.

[0035] In this embodiment, the transverse diversion bars 3 are composed of two types of short bars and one type of long bar, with the short bars located between the two long bars; the inclined diversion bars 4 as a whole are composed of diversion bars with two different inclination angles, one row inclined at 30 degrees and the other row inclined at 45 degrees, so that the coolant can conveniently flow through the staggered transition component 13.

[0036] In a further embodiment, the upper end surfaces of the plurality of longitudinal diversion bars 122 are arranged as arc surfaces 124, and the longitudinal diversion bars 122 are provided with evenly distributed tooth grooves 123.

[0037] In this embodiment, the liquid cooling channels 5 are the gaps between each transverse diversion bar 3 for the coolant to pass through. There are five liquid cooling channels 5 arranged horizontally, and there are corresponding five longitudinal diversion bars 122. Moreover, the arc surfaces 124 provided above every five longitudinal diversion bars 122 can be smoothly connected, and the same is true for the tooth grooves 123, so that the coolant entering from the liquid inlet end 10 can be gently guided to both sides.

[0038] Please refer to Figure 6 , in a further embodiment, one end of the staggered block 132 is provided with a first staggered groove 133, and the other end is provided with a second staggered groove 134. The upper port of the second staggered groove 134 communicates with the upper part of the first partition 6, and the lower port of the second staggered groove 134 communicates with the lower part of the second partition 7. The lower port of the first staggered groove 133 is connected to the lower part of the first partition 6, and the upper port of the first staggered groove 133 is connected to the upper part of the second partition 7. Both ends of the staggered block 132 are fixedly connected with connecting plates 131, and the connecting plates 131 are fixedly connected to the inner wall of the liquid cooling tank 2.

[0039] In this embodiment, when the coolant on the first partition 6 passes through the second staggered groove 134, it can reach the lower part of the second partition 7, and the coolant on the second partition 7 can enter the lower part of the first partition 6 through the first staggered groove 133. Thus, through staggered transition, the inside of the liquid inlet area 8 is filled with the coolant that has just entered, so the temperature is lower than that of the coolant in the liquid outlet area 9; the connecting plates 131 are used to block the gaps between both ends of the staggered block 132 and the inner wall of the liquid cooling tank 2.

[0040] Please refer to Figure 7 , in a further embodiment, the diversion block 135 is provided with a first section surface 136 at the upper port of the second staggered groove 134, and the diversion block 135 is provided with a second section surface 137 at the lower port of the first staggered groove 133.

[0041] In this embodiment, the diversion block 135 is rotated 180 degrees around the volume center point of the staggered block 132 to obtain another diversion block 135, so the two diversion blocks 135 are symmetric about the staggered block 132.

[0042] In a further embodiment, two liquid inlet ends 10 are provided above the cooling plate 1, and two liquid outlet ends 11 are provided on one side of the cooling plate 1. The liquid inlet ends 10 communicate with the liquid inlet area 8, and the liquid outlet ends 11 communicate with the liquid outlet area 9.

[0043] In this embodiment, the two liquid inlet ends 10 are simultaneously connected to the output end of an external cooling circulation mechanism for pumping cooled liquid into the liquid inlet area 8, and the two liquid outlet ends 11 are simultaneously connected to the input end of the cooling circulation mechanism for extracting the liquid inside the liquid outlet area 9.

[0044] The working principle of the present utility model is as follows:

[0045] When the coolant is injected into the liquid inlet area 8 from the two liquid inlet ends 10 at the same time, the coolant above the partition one 6 will be guided by the section one 136 of the flow guiding block 135, so that the coolant reaches the liquid outlet area 9 below the partition two 7 through the staggered groove two 134 and is discharged by the liquid outlet end 11. The coolant above the partition two 7 will be guided by the section one 136 of the flow guiding block 135, so that the coolant reaches the liquid outlet area 9 below the partition one 6 through the staggered groove one 133 and is then discharged by the other liquid outlet end 11. Such a cycle continues, so that the coolant that enters first is above the cooling plate 1, and the coolant that exits later is below the cooling plate 1, thereby ensuring that the temperature of the cover plate assembly 12 above the cooling plate 1 is lower, and thus improving the cooling efficiency of the liquid cooling plate;

[0046] When the above-mentioned coolant enters the liquid inlet area 8 above the partition one 6 and the partition two 7 and the liquid outlet area 9 below both of them from the liquid inlet end 10, the coolant will be guided by the transverse flow guiding strip 3. During this process, the longitudinal flow guiding strip 122 fixed on one side of the cover plate 121 and inserted into the liquid cooling flow channel 5 will conduct longitudinal smooth guiding on the flowing coolant, so that the coolant is more evenly dispersed in the liquid inlet area 8 and the liquid outlet area 9, and thus the heat dissipation is more uniform.

[0047] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
