Technical Field

[0001] The utility model relates to the technical field of automobile control equipment, in particular to a water-cooled welded electric control box assembly. Background Art

[0002] The control system of new energy vehicles is a complex system consisting of multiple subsystems and components. These subsystems and components are interconnected through high-speed communication networks to form an efficient and intelligent control network. The main purpose of the new energy vehicle control system is to achieve efficient, safe, comfortable and environmentally friendly operation of the vehicle. During the startup of the new energy vehicle control system, a large amount of heat will be generated, so it is often necessary to cool it down by water cooling.

[0003] As disclosed in a Chinese patent: A car control system housing, application number: CN202322680619.9, comprising: a mounting plate, a mounting shell, a first sealing plate, a second sealing plate and a third sealing plate. The mounting plate is installed in the mounting shell, and a water inlet and a water outlet are provided on one side of the mounting shell. The mounting plate comprises a first mounting part, a second mounting part and a third mounting part. The first mounting part is provided with a first cavity connected to the water inlet, the first sealing plate seals and covers the first cavity, the second mounting part is provided with a second cavity connected to the first cavity, the second sealing plate seals and covers the second cavity, the third mounting part is provided with a third cavity connected to the second cavity, the third cavity is connected to the water outlet, the side of the third mounting part facing away from the third cavity is the core mounting surface, and the third sealing plate seals and covers the third cavity, which can solve the problem that water can circulate in the control system to reduce severe heating of the panel.

[0004] However, in the above technical solution, the principle of water cooling utilizes the high specific heat capacity and thermal conductivity of water to absorb and conduct the heat generated by electronic equipment, and then pushes the hot water into the radiator. The radiator dissipates the heat from the water with the assistance of a fan. When the electronic control box assembly is cooled by a water cooling cycle, only the cooling water close to the inner wall of the water cooling cycle cavity can effectively absorb the heat from the electronic control box assembly, resulting in a lower heat exchange area and lower heat dissipation efficiency. Utility Model Content

The radiator dissipates the heat from the water with the assistance of a fan. When the electric control box assembly is cooled by a water cooling cycle, only the cooling water close to the inner wall of the water cooling cycle cavity can effectively absorb the heat on the electric control box assembly, resulting in a low heat exchange area and low heat dissipation efficiency.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A water-cooled welded electric control box assembly includes an assembly main body, a sealing ring is provided on one side above the assembly main body, two first cavities are provided on one side below the assembly main body, a second cavity is provided on one side of the first cavity, flow channel plates are provided in the first cavity and the second cavity, a first connecting groove is provided between the two first cavities, a second connecting groove is provided between the second cavity and one first cavity, a sealing plate is provided on the first cavity and the second cavity, a heat conducting plate is provided on the sealing plate, and a liquid inlet pipe and a liquid outlet pipe are provided on one side of the assembly main body.

[0008] Preferably, the two first cavities are connected via a first communicating groove, and the second cavity is connected to one first cavity via a second communicating groove.

[0009] Preferably, the side of the heat conducting plate close to the sealing ring passes through the sealing plate, the liquid inlet pipe is communicated with a first cavity, and the liquid outlet pipe is communicated with a second cavity.

[0010] Preferably, the flow channel plate includes a flow channel plate base, two support plates are provided on one side of the flow channel plate base, and a heat conducting plate is provided on the support plates.

[0012] Preferably, the flow channel plate base is fixedly connected to the assembly body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) During heat dissipation, the utility model adjusts the flow channel width inside the first cavity and the second cavity through the multi-layer fins to form a narrower micro-channel, thereby enhancing the convective heat transfer coefficient. Since the narrower the width, the greater the coolant flow rate, the natural convective heat transfer coefficient increases, further increasing the heat dissipation area. At the same time, part of the heat on the assembly body is conducted through the heat conducting plate, and then the heat on the heat conducting plate is transferred through the heat conducting plate in contact with the heat conducting plate. The heat is then dispersed through the heat conducting plate and the multi-layer fins, and the heat dissipation area is increased by the heat conducting plate and the multi-layer fins. By increasing the heat exchange area, the heat dissipation is improved, thereby improving the water cooling heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with 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.

[0021] like Figures 1 to 3 As shown, a water-cooled welded electric control box assembly includes an assembly main body 1, a sealing ring 2 is provided on the upper side of the assembly main body 1, two first cavities 3 are provided on the lower side of the assembly main body 1, a second cavity 4 is provided on one side of the first cavity 3, a flow channel plate 5 is provided in the first cavity 3 and the second cavity 4, a first connecting groove 6 is provided between the two first cavities 3, a second connecting groove 7 is provided between the second cavity 4 and one first cavity 3, a sealing plate 8 is provided on the first cavity 3 and the second cavity 4, a heat conducting plate 9 is provided on the sealing plate 8, and a liquid inlet pipe 10 and a liquid outlet pipe 11 are provided on one side of the assembly main body 1.

[0022] like Figure 4 As shown, in another embodiment of the present invention, the flow channel plate 5 includes a flow channel plate base 501, two support plates 502 are provided on one side of the flow channel plate base 501, and a heat conducting plate 503 is provided on the support plate 502;

[0023] A multi-layer fin 504 is provided between the flow channel plate base 501 and the heat conducting plate 503. When cooling water enters the first cavity 3 and the second cavity 4, the flow channel width inside the first cavity 3 and the second cavity 4 is adjusted by the multi-layer fin 504 to form a narrower micro-channel, thereby enhancing the convection heat transfer coefficient. Since the narrower the width, the greater the flow rate of the coolant, the natural convection heat transfer coefficient increases, further increasing the heat dissipation area. At the same time, the heat on the heat conducting plate 9 is transferred through the heat conducting plate 503 in contact with the heat conducting plate 9, and then the heat is dispersed through the heat conducting plate 503 and the multi-layer fin 504, and the heat dissipation area is increased by the heat conducting plate 503 and the multi-layer fin 504, thereby improving the heat dissipation performance by increasing the heat exchange area.

[0024] The working principle of a water-cooled welded electric control box assembly:

[0025] When in use, first, the cooling water is injected into the first cavity 3 through the liquid inlet pipe 10, and then the cooling water in the first cavity 3 flows into another first cavity 3 through the first connecting groove 6, and then the cooling water flows into the second cavity 4 through the second connecting groove 7. Finally, the cooling water in the second cavity 4 is moved to the designated position through the liquid outlet pipe 11, thereby completing the cooling water circulation and dissipating the heat of the assembly body 1. During the heat dissipation period, the width of the flow channel inside the first cavity 3 and the second cavity 4 is adjusted by the multi-layer fins 504 to form a narrower microchannel, thereby increasing the heat dissipation. Strong convection heat transfer coefficient. Since the narrower the width, the greater the coolant flow rate, the natural convection heat transfer coefficient increases, further increasing the heat dissipation area. At the same time, part of the heat on the assembly body 1 is conducted through the heat conducting sheet 9, and then the heat on the heat conducting sheet 9 is transferred through the heat conducting plate 503 that is in contact with the heat conducting sheet 9. The heat is then dispersed through the heat conducting plate 503 and the multi-layer fins 504, and the heat dissipation area is increased by the heat conducting plate 503 and the multi-layer fins 504. By increasing the heat exchange area, the heat dissipation is improved, and the water cooling heat dissipation efficiency is improved.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
