Description

Technical Field

[0001] This invention relates to the field of plate heat exchangers, and more specifically to a high-pressure plate heat exchanger and its process. Background Technology

[0002] New energy vehicles are a type of green and environmentally friendly vehicle that primarily relies on electricity for energy. Existing new energy vehicles typically use batteries and fuel cells as their power source. Batteries are suitable for pure electric vehicles and include lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries. Existing charging methods for new energy vehicles are mainly divided into detachable charging and charging pile charging, with most existing new energy vehicles using charging piles.

[0003] However, existing plate heat exchangers are installed inside the airflow channels of equipment, directly exchanging heat with the airflow within these channels. While they can exchange heat with a single piece of equipment, the heat exchange efficiency can only be controlled by the airflow velocity. This can easily lead to a mismatch between the heat exchange efficiency of the heat exchange gas and the heating efficiency of the equipment, resulting in either excessive or insufficient heat exchange. Furthermore, existing plate heat exchangers are fixed to the inner wall of the equipment, allowing them to exchange heat with only a single piece of equipment and failing to meet the requirement of simultaneous heat exchange with multiple pieces of equipment. Therefore, we propose a high-pressure plate heat exchanger. Summary of the Invention

[0006] Preferably, the four corner outer walls of the bottom plate and the top plate are fixedly provided with fixing plates, and a through fixing hole is opened in the center of the fixing plate. A vertically upward bolt is inserted into the inner wall of the fixing hole, and a nut is screwed onto the top outer wall of the bolt, so as to facilitate fixing the first heat exchange module and the second heat exchange module in the present invention.

[0007] Preferably, each of the four bolts has a foot pad fixed to one end of its bottom, which facilitates the installation and placement of the present invention.

[0008] Preferably, the first heat exchange module includes a first positioning plate, a first air guide plate, a first diversion support plate distributed at equal intervals, and two first sealing plates. The two first sealing plates are fixed to both sides of the first air guide plate and the first positioning plate. The top and bottom outer walls of the first diversion support plates distributed at equal intervals are fixedly connected to the outer walls of the first positioning plate and the first air guide plate, respectively. The top outer wall of the first air guide plate has first heat exchange holes distributed at equal intervals. The second heat exchange module includes a second positioning plate, a second air guide plate, a second diversion support plate distributed at equal intervals, and two second sealing plates. The two second sealing plates are fixed to both sides of the second positioning plate and the second air guide plate. The top and bottom outer walls of the second diversion support plates distributed at equal intervals are fixedly connected to the outer walls of the second positioning plate and the second air guide plate, respectively.

[0010] Preferably, the first heat exchange module and the second heat exchange module are made of aluminum plate material, and the thickness of the aluminum plate material of the first heat exchange module and the second heat exchange module is 0.5-0.6mm.

[0011] Preferably, one end of the external threaded pipe joint is equipped with a matching tee pipe and multi-way pipe, which are connected to the external threaded pipe joint through the tee pipe and multi-way pipe, enabling multiple external threaded pipe joints to be connected.

[0012] S1: In use, first insert the strip-shaped connecting pipe into the inner wall of the strip-shaped exhaust port and the strip-shaped air inlet respectively. The gas discharged from the equipment and the gas of heat exchange convection are connected to the two strip-shaped air inlets respectively through the strip-shaped connecting pipe via the external threaded pipe joint, flow valve, gas collecting pipe, and diverter pipe. The gas after heat exchange through this invention is connected to the equipment exhaust port through the strip-shaped connecting pipe via the diverter pipe, gas collecting pipe, flow valve, and external threaded pipe joint.

The airflow in the second heat exchange module that is diverted by the second diversion support plate is discharged into the strip-shaped connecting pipe connected to the equipment outlet through the strip-shaped exhaust port. The heat-exchanged airflow flows into the equipment through the strip-shaped connecting pipe, diversion pipe, gas collecting pipe, flow valve and external threaded pipe joint.

[0014] S3: When the heat exchange demand of the same equipment is large, a three-way pipe or a multi-way pipe is used to connect the external threaded pipe joints located on the same side of the present invention, and then the equipment is connected to the three-way pipe or the multi-way pipe through the pipe. This allows the heat exchange equipment to be connected to multiple first heat exchange modules and second heat exchange modules at the same time, which is beneficial to improve the heat exchange effect of the equipment, so as to meet the heat exchange effect of the equipment, avoid excessive heat exchange effect, and prevent insufficient heat exchange effect.

[0041] Working principle of this invention:

[0042] Refer to the instruction manual appendix Figure 1-11In use, first insert the strip-shaped connecting pipe 23 into the inner walls of the strip-shaped exhaust port 22 and the strip-shaped air inlet 21 respectively. Connect the gas discharged from the equipment and the gas undergoing heat exchange convection through pipe fittings via external threaded pipe fitting 27, flow valve 26, gas collecting pipe 24, and diverter pipe 25, and then through the strip-shaped connecting pipe 23 to the two strip-shaped air inlets 21 respectively. The gas after heat exchange through this invention connects to the equipment exhaust inlet via the strip-shaped connecting pipe 23, diverter pipe 25, gas collecting pipe 24, flow valve 26, and external threaded pipe fitting 27. This process is repeated once the first heat exchange... The strip-shaped air inlets 21 and strip-shaped exhaust ports 22, fixedly located on the outer walls of both sides of the heat exchange module 9 and the second heat exchange module 10, are respectively connected to the strip-shaped connecting pipe 23. This allows for simultaneous heat exchange for multiple devices, with multiple devices exchanging heat uniformly at the same location. This avoids the direct air intake from the side wall of the existing plate heat exchanger, preventing airflow from impacting the side wall of the plate heat exchanger and preventing turbulence in the airflow. This improves the stability of the heat exchanger. The heated gas and the cooling convective gas are respectively input into the first heat exchange module through the strip-shaped air inlets 21. Inside the heat exchange module 9, hot and cold air flows are convected through the first diversion support plate 13 and discharged through the first heat exchange hole 14 at the top of the first air guide plate 12. The gas undergoes diversion and heat exchange. The gas discharged through the first heat exchange hole 14 is discharged into the second heat exchange module 10 through the second heat exchange hole 19. The airflow in the second heat exchange module 10, diverted by the second diversion support plate 18, is discharged through the strip exhaust port 22 into the strip connecting pipe 23, which is connected to the equipment inlet. The heat-exchanged airflow then flows through the strip connecting pipe 23, the diversion pipe 25, and the collection pipe... The air pipe 24, flow valve 26, and external threaded pipe joint 27 flow into the equipment. When the heat exchange demand of the same equipment is large, a three-way pipe or a multi-way pipe is used to connect the external threaded pipe joint 27 located on the same side of the present invention. Then, the equipment is connected to the three-way pipe or the multi-way pipe through the pipe, so that the heat exchange equipment is connected to multiple first heat exchange modules 9 and second heat exchange modules 10 at the same time. This is beneficial to improve the heat exchange effect of the equipment, so as to meet the heat exchange effect of the equipment, avoid excessive heat exchange effect, and prevent insufficient heat exchange effect.
