Description

Technical Field

[0001] The utility model relates to the field of automobile radiators, in particular to a heat sink for an automobile water tank. Background Art

[0002] The automobile radiator is an important component of the automobile water-cooled engine. As an important component of the water-cooled engine's heat dissipation circuit, it can absorb the heat of the cylinder and prevent the engine from overheating. Due to the large specific heat capacity of water, the temperature does not rise much after absorbing the heat of the cylinder. Therefore, the heat of the engine is transmitted through the cooling water liquid circuit, using water as a heat carrier to conduct heat, and then dissipated by convection through a large area of radiator fins to maintain the appropriate operating temperature of the engine. At present, most radiator radiators are composed of long strips of heat dissipation cores, which results in a shorter water flow path, resulting in a reduced heat dissipation area and poor heat dissipation effect.

[0003] Therefore, we propose a heat sink for automobile water tank to solve the above problems. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1 to 4 As shown, a heat sink for an automobile radiator comprises: a water inlet 1 and a water outlet 2 and a heat dissipation core 3 arranged between the water inlet 1 and the water outlet 2, the heat dissipation core 3 comprises a plurality of flow channel groups 31, a water channel 310 is arranged in the flow channel group 31, the water channel 310 is connected with the water inlet 1 and the water outlet 2, the water channel 310 is a bent structure, specifically, the bending part of the bent structure is an arc structure, the heat dissipation core 3 further comprises heat dissipation fins 32, the heat sink is arranged on both sides of the water channel 310, the angle of the folding part of the water channel 310 is between 15° and 30°, the water channel 310 is distributed in a ring shape in the flow channel group 31, and the plurality of flow channel groups 31 are arranged in parallel, and the spacing between each flow channel group 31 is the same.

[0027] Several flow channel groups 31 are set in the heat dissipation fins 32, so that the overall contact area of the heat dissipation fins with the cooling water is increased, and a better heat dissipation effect is achieved. At the same time, the water channel 310 in the flow channel group 31 is a bent structure, which lengthens the water flow and prolongs the contact time between the cooling water and the heat dissipation fins 32. In addition, the folded shape is further refined to increase the contact area between the cooling water and the heat dissipation fins 32, thereby further improving the heat dissipation effect. The spacing between the several flow channel groups 31 is the same, and the angle of the folded water channel 310 is between 15° and 30°, so that the cooling water passes through each heat dissipation fin 32 evenly, making the heat dissipation more uniform.

[0028] In a preferred embodiment of the present invention, the heat dissipation core 3 also includes a top plate 33, a bottom plate 34 and a sealing plate 35. The water inlet 1 is arranged on the top plate 33, the water outlet 2 is arranged on the bottom plate 34, and the sealing plates 35 are arranged on both sides of the flow channel group 31. A fixing device is provided on the inner side of the sealing plate 35, and the fixing device is provided with a fixing bolt, which is a hand-tightened bolt. A disassembly device is provided on the outer side of the sealing plate 35, and a matching fixing sleeve 36 is provided on the disassembly device. By arranging the top plate 33, the bottom plate 34 and the sealing plate 35 on the heat dissipation core 3, it has a convenient and fast assembly structure while improving the heat dissipation efficiency. After the bottom plate 34 and the top plate 33 are sealed and connected, a water-cooled heat sink is formed. Cooling water is input from the water inlet 1 through the water channel 310 and then discharged from the water outlet 2. The cooling water takes away the heat and cools it down while the heat dissipation fins 32 also dissipate heat. It has a convenient and fast assembly structure while improving the heat dissipation efficiency.

[0029] In a preferred embodiment of the present invention, the heat sink is made of heat-conducting material, and the sealing plate 35 is made of heat-insulating material.

[0030] When the present invention is in use, the heat sink is fixed on the water tank that needs heat dissipation. Specifically, a fixing sleeve 36 is provided on the outside of the sealing plate 35 for fixing. Because the fixing sleeve 36 is provided, the connection strength between the devices is increased, and the stability of the device connection is improved. In addition, the detachable device and the fixing plate can protect the heat dissipation core, reduce the vibration impact generated during the driving of the car, and effectively extend the service life of the device. In addition, the fixing plate provides convenient installation conditions for the water tank radiator body, and can also increase the overall strength of the device to ensure the normal operation of the water tank radiator. The detachable fixing method also facilitates the connection between the heat sink and other components, thereby improving the practical performance of the device.

[0031] After fixing the heat sink to the water tank, add coolant to the water inlet 1, and the coolant slowly flows out of the water outlet 2 through the water channel 310. Since several flow channel groups 31 are provided in the heat dissipation fins 32, the overall contact area of the heat sink with the cooling water is increased, and a better heat dissipation effect is achieved. At the same time, the water channel 310 in the flow channel group 31 is a bent structure, which lengthens the water flow and prolongs the contact time between the cooling water and the heat dissipation fins 32. In addition, the folded shape is further refined to increase the contact area between the cooling water and the heat dissipation fins 32, thereby further improving the heat dissipation effect. The spacing between the several flow channel groups 31 is the same, and the angle of the folded water channel 310 is between 15° and 30°, so that the cooling water passes through each heat dissipation fin 32 evenly, making the heat dissipation more uniform.

[0032] The above embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art will be able to make various modifications and improvements without departing from the spirit of the present invention. These modifications and improvements are equivalent to those made to the above embodiments based on the essential technology of the present invention and fall within the scope of protection of the present invention.
