Embodiment 1

[0025] see Figure 1-3 , an integrated microchannel heat exchanger with a uniform liquid device, including a heat exchanger top plate 1, a thermal fluid interface 2 is provided on the upper surface of the heat exchanger top plate 1, and the inside of the thermal fluid interface 2 is connected to the heat exchanger top plate 1 The lower surface of the heat exchanger top plate 1 is provided with a cold fluid interface 3, the number of the hot fluid interface 2 and the cold fluid interface 3 are two, and the two hot fluid interfaces 2 and the two cold fluid interfaces 3 are staggered at the four corners of the heat exchanger top plate 1, so that the cold fluid and hot fluid can enter the bottom of the heat exchanger top plate 1 through the cold fluid interface 3 and the hot fluid interface 2 respectively, and the inside of the cold fluid interface 3 and the heat exchanger top plate 1 The lower surface of the heat exchanger top plate 1 is fixedly connected with the hot-side heat e...

Embodiment 2

[0028] see Figure 4 , the upper surface of the damping plate 8 is provided with a damping hole 9, the inside of the damping hole 9 is connected with the lower surface of the damping plate 8, the number of the damping holes 9 is three, and the three damping holes 9 are evenly arranged on the bottom of the damping plate 8 On the surface, the three damping plates 9 disperse the fluid, so that the distribution of the fluid is more uniform.

Embodiment 3

[0030] see Figure 5 , the upper surface of the damping plate 8 is provided with a damping hole 9, the inside of the damping hole 9 communicates with the lower surface of the damping plate 8, the cross section of the damping hole 9 is elliptical, and the elliptical damping hole 9 makes the area of ​​the fluid flow Larger, more fluid enters the lower surface of the damping plate 8 through the damping hole 9, so that the heat exchange effect of the fluid is better, and the efficiency of the heat exchanger is higher.

[0031]To sum up, the integrated microchannel heat exchanger with liquid equalization device is provided with the top plate 1 of the heat exchanger, the heat exchange plate 4 on the hot side, the heat exchange plate 10 on the cold side and the bottom plate 14 of the heat exchanger, The fluid can pass through the top plate of the heat exchanger 1 and enter the hot side heat exchange plate 4 and the cold side heat exchange plate 10 for heat exchange, and the first flu...

Abstract

The invention relates to the technical field of heat exchangers, and discloses an integrated microchannel heat exchanger with a liquid homogenizing device. The integrated microchannel heat exchanger comprises a heat exchanger top plate, and a hot fluid connector is formed in the upper surface of the heat exchanger top plate. The interior of the hot fluid connector communicates with the lower surface of the heat exchanger top plate. A cold fluid connector is formed in the upper surface of the heat exchanger top plate. According to the integrated microchannel heat exchanger with the liquid homogenizing device, by arranging the heat exchanger top plate, a hot side heat exchange plate sheet, a cold side heat exchange plate sheet and a heat exchanger bottom plate, fluid can pass through the heat exchanger top plate to enter the hot side heat exchange plate sheet and the cold side heat exchange plate sheet for heat exchange; and by arranging a first fluid distributing groove, a second fluiddistributing groove, a damping plate and a damping hole, the fluid is distributed into the first fluid distributing groove and the second fluid distributing groove by the damping plate through the damping hole, and therefore the heat exchanger is better in heat exchange effect and thorough in heat exchange.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to an integrated microchannel heat exchanger with a liquid uniform device. Background technique [0002] The integrated microchannel heat exchanger is a three-dimensional structure manufactured by vacuum brazing or vacuum diffusion welding that can be used for heat exchange between media. The internal channel size of the micro-channel heat exchanger reaches the micron level, which belongs to the micro-scale heat transfer structure, and has the advantages of high heat exchange efficiency and high pressure resistance. The integrated microchannel heat exchanger is composed of multi-layer hot side heat exchange plates and cold side heat exchange plates. Whether the heat exchange capacity of the heat exchanger can be fully utilized depends on whether the cold and hot fluids can be evenly distributed to the Each cold and hot side heat exchange plates. The uneven distribution of ...
