Plate heat exchanger structure of laser cold water machine with air blowing anti-icing function

Abstract

This utility model relates to the field of anti-icing technology, specifically a plate heat exchanger structure for a laser chiller with air-blowing anti-icing function. It includes a laser chiller, an air-blowing component located outside the inlet of the chiller, and a recovery component located outside the outlet. The air-blowing component includes a fixed plate, with gears connected to the outer wall of the fixed plate. After use, the gas blows out any remaining purified water from the chiller. The blown-out purified water is blocked by a baffle and falls into a water storage tank, preventing the risk of freezing and explosion from the source, thus improving the chiller's safety and avoiding water waste. It also ensures no water residue remains inside the chiller, further enhancing the anti-icing effect. The design of the first and second hydraulic cylinders eliminates the need for manual operation, ensuring that the blowing action is completed after each shutdown, improving operational convenience and reliability.

Description

Technical Field

[0001] This utility model relates to the field of anti-icing technology, specifically to a plate heat exchanger structure for a laser chiller with air-blowing anti-icing function. Background Technology

[0002] Laser chillers are industrial refrigeration devices specifically designed for laser equipment. They use a water circulation system to cool and control the temperature of the laser generator, ensuring stable operation and extending the lifespan of the laser equipment. Their core functions include preventing overheating and damaging components, and improving processing accuracy. They are widely used in laser cutting, welding, marking, and engraving.

[0003] However, after use, some purified water remains inside the existing laser chiller. Due to the lack of a cleaning mechanism, in areas where the temperature is prone to sudden drops in autumn and winter, the remaining purified water may freeze, causing a risk of expansion and explosion, which is highly dangerous. Utility Model Content

The recycling assembly includes a water storage tank, with guide rods installed on both sides inside the water storage tank, a baffle between the guide rods, a fixing plate installed on the upper outer side of the baffle, and a second hydraulic cylinder installed below the end of the fixing plate away from the baffle.

[0011] Preferably, the drive rod of the second hydraulic cylinder is fixedly connected to the fixed plate, and the second hydraulic cylinder is fixedly connected to the water storage tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) After the use of the plate heat exchanger structure of the laser chiller of this utility model is completed, the sensors inside the first hydraulic cylinder and the second hydraulic cylinder sense that the chiller has stopped working. The drive rod of the first hydraulic cylinder drives the rack to move downward along the guide block. The rack drives the gear to rotate around the fixed plate. The gear drives the blower to rotate. The blower drives the air pipe to move. Finally, the rack presses the control switch, the air pipe is aligned with the water inlet of the laser chiller, the blower is started, and the blower sends the gas into the laser chiller through the air pipe. The drive rod of the second hydraulic cylinder drives the fixed plate to move upward. The fixed plate drives the baffle to move along the guide rod. Finally, the baffle blocks the water outlet of the laser chiller. The gas blows out the pure water remaining in the laser chiller. The blown pure water is blocked by the baffle and falls into the water storage tank. This avoids the risk of freezing and bursting from the source, improves the safety of the chiller, avoids the waste of water resources, and ensures that there is no water residue inside the laser chiller, further strengthening the anti-icing effect.

[0013] (2) The plate heat exchanger structure of the laser chiller of this utility model is designed with a first hydraulic cylinder and a second hydraulic cylinder. The first hydraulic cylinder and the second hydraulic cylinder are linked with the laser chiller shutdown system respectively. After the laser chiller triggers the shutdown command, the first hydraulic cylinder and the second hydraulic cylinder start respectively.
