Problems solved by technology

However, even so, the cooling fan is greatly affected by the interference of the surrounding air environment, can only provide insufficient cooling effect, and often directly guides the dirty, humid, corrosive and other unfavorable factors in the ambient air to the cabinet to be cooled The control module constitutes a major hidden danger in the operation of the electric control cabinet and even causes equipment damage

Abstract

The invention discloses a fully-closed intelligent electric control cabinet cooling system, which comprises a compressor, a condensation heat recovery adjustment valve, a heat recovery coil, an electric valve, a condensation coil, a condensation fan, a dry filter, a throttle valve, an evaporation coil, a baffle board, an electric heater, a circulating fan and a case. The cooling capacity for cooling each electronic and electric module inside the electric control cabinet is from the refrigerating capacity generated by a vapor compression refrigeration system at the evaporation coil, a constant dew point temperature mode enables the temperature and the humidity of the circulating cooling air to be controlled precisely, and due to the condensation heat recovery design, the cooling system is energy-saving and environmental friendly. The defects that the cooling mode of the cooling fan is largely influenced by interference of the surrounding air environment, and only insufficient cooling effects can be provided can be overcome.

Description

technical field [0001] The invention relates to a system for cooling a fully enclosed intelligent electric control cabinet by using a vapor compression refrigeration cycle. Background technique [0002] A large number of high-calorie control modules and various discrete electronic and electrical components are integrated in a common fully enclosed intelligent electric control cabinet. Among them, the electronic control system, variable speed drive system, servo system and programmable logic control system are extremely sensitive to heat and pollution. The high temperature and high humidity air environment not only seriously affects the electrical control accuracy and control stability, but also causes premature aging of electronic and electrical components working in harsh atmospheres and shortens the service life. Once the temperature or humidity inside the control cabinet is too high, it will cause accidental burning of electronic and electrical components, and even cause ...
