In this embodiment, the printed circuit board heat exchanger with noise elimination function is formed by stacking and pressure welding a series of heat exchange plates containing micro grooves, wherein the heat exchange plates include a cold fluid heat exchange plate and a hot fluid heat exchange plate which are overlapped and connected with each other.
As shown in fig. 8 and 9, the printed circuit plate heat exchanger having the noise-canceling function includes a cold fluid inlet flange 100, a cold fluid outlet flange 200, a hot fluid inlet flange 300, a hot fluid outlet flange 400, and a cooler body. The cold fluid inlet flange 100 and the cold fluid outlet flange 200 are respectively arranged on the upper right side and the lower left side, and the hot fluid inlet flange 300 and the hot fluid outlet flange 400 are respectively arranged on the lower right side and the upper left side, so that cold and hot fluids flow in a mutually countercurrent manner, and the heat exchange effect is enhanced. Firstly, a heat exchange plate containing micro-grooves is manufactured on a metal thin plate by adopting methods such as laser, chemical etching and the like, and then the heat exchange plate is formed by stacking and pressure welding.
Because the drive device is often arranged on the cold fluid heat exchange plate, the cold end installation drive device is taken as an example in the embodiment, and the purpose of reducing the noise of the cooling working medium emission is realized by utilizing the elbow sound absorption structure in the cold fluid heat exchange plate.
As shown in fig. 1, a heat exchange channel is provided in the cold fluid heat exchange plate, and an elbow sound absorption structure is installed at the inlet elbow 5 and the outlet elbow 13 corresponding to the cold fluid heat exchange plate. The fluid inlet 1 is communicated with the fluid outlet 2 through an inlet elbow 5, an inlet distribution cavity 6, an inlet distribution structure 7, an inlet bending channel structure 8, a corrugated channel structure 9, an outlet bending channel structure 10, an outlet distribution structure 11, an outlet distribution cavity 12 and an outlet elbow 13.

The hot fluid inlet 3 is communicated with the hot fluid outlet 4 through a hot fluid inlet elbow 16, a hot fluid corrugated channel structure 15 and a hot fluid outlet elbow 14 in sequence. The hot fluid heat exchange plate is different from the cold fluid heat exchange plate in that a hot fluid inlet 3 is connected with a hot fluid inlet flange 300, a hot fluid outlet is connected with a hot fluid outlet flange 400, only a hot fluid corrugated channel structure 15 needs to be arranged, and other noise elimination structures do not need to be arranged due to the fact that the driving equipment is completely arranged at the cold end.
In the working process, cold fluid enters the inlet elbow 5 through the fluid inlet 1, and the first silencing of the cooling working medium on the cold fluid heat exchange plate is realized through the elbow sound absorption structure. The cooling water passing through the elbow sound absorption structure enters the inlet distribution cavity 6, so that the function of distributing the cooling working medium is realized, and meanwhile, the secondary noise elimination is realized by means of the expansion noise elimination principle. And then enters the inlet flow dividing structure 7, cold fluid is introduced into each heat exchange channel behind the inlet flow dividing structure, and third noise elimination can be realized by virtue of a T-shaped labyrinth channel formed by the T-shaped plate 701. The cold fluid then effectively absorbs the noise of the working fluid in the zigzag labyrinth formed by the zigzag plates 801, so as to realize the fourth noise elimination. The cold fluid can then be damped a fifth time by means of the damping principle of the corrugated plate 901. And then the corresponding noise elimination effect is carried out through the outlet bending channel structure 10, the outlet shunting structure 11, the outlet distribution cavity 12 and the outlet elbow 13 in sequence, so that the transmission of flow noise generated by dynamic equipment along the printed circuit board type heat exchanger with the noise elimination function can be greatly inhibited. Meanwhile, the hot fluid enters the hot fluid inlet elbow 16 through the hot fluid inlet 3, and then enters the hot fluid outlet 4 through the hot fluid corrugated channel structure 15 and the hot fluid outlet elbow 14 in sequence. In the flowing process of the cold fluid and the hot fluid, the cold fluid and the hot fluid flow in a mutually countercurrent way, so that the cold fluid and the hot fluid can exchange heat quickly.
In other embodiments, the number of the cold fluid heat exchange plates and the hot fluid heat exchange plates can be multiple, and the cold fluid heat exchange plates and the hot fluid heat exchange plates are sequentially and alternately connected in an overlapping manner.
