Problems solved by technology

Its disadvantages are: According to thermodynamics and fluid mechanics, in the later stage of cooling water temperature rise, the heat flow resistance will increase rapidly, that is, the heat absorption capacity will decrease rapidly. Affected by the heat flow resistance, the cooling capacity of the rear section of the cooling water channel will be greatly reduced. decline, the overall cooling capacity of the radiator is unreliable
[0004] In addition, in the prior art, cooling water channels are connected in parallel for cooling, but the cooling path is short and the cooling water is not used sufficiently. The electric vehicle module needs to consume more energy for cooling water. Refrigeration, obviously, this method is not conducive to the battery life of electric vehicles

Embodiment 1

[0027] Figure 1 to Figure 5 Among them, a water-cooled radiator with good heat absorption performance includes a radiator body 1, a water inlet pipe 2 and a water outlet pipe 3, and is characterized in that the radiator body 1 is provided with a cooling water channel 4 connecting the water inlet pipe 2 and the water outlet pipe 3 , the cooling water flows through the water inlet pipe 2, the cooling water channel 4 and the water outlet pipe 3 in sequence; The interior of the device body 1 is arranged in a reciprocating "S" shape. The radiator body 1 is provided with a bypass layer 5 on a plane parallel to the cooling water channel 4. The bypass layer 5 is a copper product embedded in the radiator body 1. The bypass layer 5 and the cooling channel 4 are bonded and fixed by heat-conducting adhesive. . The bypass layer 5 is provided with a cavity for circulating cooling water, and the bypass layer 5 is provided with a water inlet 51 and a water outlet 52 , and the water inlet 5...

Embodiment 2

[0029] Such as Figure 6 As shown, a water-cooled radiator with good heat absorption performance differs from Embodiment 1 in that the water inlet pipe 2 and the water outlet pipe 3 are located on the same side of the radiator body 1 .

[0030] The one-way flow of the cooling water body in the bypass layer 5 is guaranteed by the one-way valve 53, preventing the water body in the cooling pipeline from flowing back to the bypass layer 5; compared with the cooling water in the cooling water channel 4, the cooling water in the bypass layer 5 The heat transfer speed is far beyond, so that the temperature difference between the cooling water in the bypass layer 5 is small, so that the cooling water in the bypass layer 5 can balance the heat absorption efficiency of each part of the cooling water channel 4 below it; After the cooling water in the passing layer 5 absorbs part of the heat, the temperature difference of the cooling water channel 4 can be kept larger than that of the mod...

Abstract

The invention discloses a water-cooling radiator with good heat absorption performance. The water-cooling radiator comprises a radiator body, a water inlet pipe and a water outlet pipe, a cooling water channel communicated with the water inlet pipe and the water outlet pipe is arranged in the radiator body, and cooling water sequentially flows through the water inlet pipe, the cooling water channel and the water outlet pipe; and the radiator body is provided with a bypass layer on a plane parallel to the cooling water channel, the bypass layer is provided with a water inlet and a water outlet, the water inlet of the bypass layer is communicated with the water inlet pipe, the water outlet of the bypass layer is connected into the cooling water channel, and the water outlet is provided with a one-way valve. The water-cooling radiator has the advantages that cooling water is fully utilized to absorb heat, the water-cooling radiator is suitable for being applied to an IGBT module, and heat flow resistance at the rear end of the cooling water channel is reduced, so cooling balance of the IGBT module is guaranteed, and heat dissipation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water cooling and heat dissipation, in particular to a water cooling radiator with good heat absorption performance. Background technique [0002] Water-cooled radiators are widely used in IGBT modules. Generally, spoilers are installed in the cooling water channel to destroy or thin the boundary layer of laminar flow, thereby promoting heat exchange inside the water body to improve heat dissipation efficiency; Cooling water flow rate and other methods to improve the heat dissipation efficiency of the water-cooled radiator. However, as the IGBT module continues to upgrade with the standards of electric vehicles, the heat dissipation performance required is getting higher and higher. At present, the water-cooled radiator still needs to be continuously improved, and there are great deficiencies. [0003] For example, in the Chinese patent literature, the application number is CN201610907030X, and the publi...
