How to solve the shortage of cooling in the semiconductor cooling cycle system

The semiconductor cooling cycle system is a device for cooling the semiconductor heat-generating part in the refrigeration equipment. If the cooling capacity of the LNEYA semiconductor cooling circulation system is insufficient during operation, it is necessary to check in time to see what has gone wrong.

When the cooling capacity of the semiconductor cooling cycle system is insufficient, it is first determined whether the filter is blocked. The blockage of the filter includes: suction filter blockage and dry filter blockage. At this time, it only needs to be cleaned and cleaned.

By observing to determine whether it is too small or too large for the expansion valve to open, by adjusting the amount of water. The problem of leakage of the filling agent in the temperature sensor of the expansion valve can be solved by opening the cooling tower. A dirty or blocked ice valve can be solved by cleaning. If the bearing of the compressor is worn out, the clearance is too large, and the problem of insufficient cooling capacity can be solved by inspection and replacement. Use components with precise structure, high reliability and long life. To ensure the stable operation of the unit.

The condenser of the semiconductor cooling cycle system selects the shell-and-tube condenser, which can optimize the temperature field distribution and the flow field distribution of the refrigerant, and the heat exchange efficiency is high. The outer fin design of the heat exchange tube enhances the heat exchange condensation and improves the heat exchange efficiency outside the tube. Insufficient refrigerant charge and excessive refrigerant leakage may also cause insufficient cooling capacity in the semiconductor cooling cycle system. These problems can be solved by adding or subtracting the refrigerant charge, leaking, and adding refrigerant after maintenance.


Semiconductor cooling cycle system evaporator with too small evaporator frosting too thick> There are a large number of lubricants in the evaporator or the liquid storage valve of the liquid storage valve is too small, the cooling water is insufficient or the water temperature is too high, etc. The cooling cycle system has insufficient cooling capacity. If the evaporator is too small, it can reduce the heat load or replace the evaporator. If the evaporator frost is too thick, it needs to be frosted regularly. There is a lot of lubricating oil in the evaporator, and the refrigeration oil, condenser or reservoir is recovered. The outlet valve is opened too small, and the outlet valve is properly opened.

In addition, there is excess air in the refrigeration system of the semiconductor cooling cycle system, and the energy adjustment indication is incorrect and needs attention. Excess air in the refrigeration system can be solved by discharging air. If the energy adjustment indication is incorrect, the indicator light may be broken and can be solved by inspection and replacement. The reason for the insufficient cooling capacity is as shown above. It is recommended that users find out that they can contact the manufacturer in time for after-sales solution.
