Abstract

The invention discloses a cooling and dehumidifying device and a converter applying the same. The cooling and dehumidifying device comprises a cooling air passage component, and the cooling air passage component comprises a fan, an evaporator and an air passage formed between the fan and the evaporator, wherein the air passage is used for cooperating with the inside of an electrical cabinet, to be cooled and dehumidified, to form a circulating air passage, and the evaporator is filled with cooling media for cooling and dehumidifying the inside of the electrical cabinet. The cooling and dehumidifying device has the advantages that on the premise of meeting cooling power requirements, good cooling and dehumidifying effects and constant-temperature constant-humidity control for the inside of the electrical cabinet can be achieved by adjusting the outside cooling media, and unsusceptibility of environment temperature and humidity in the cabinet to outside environment temperature and humidity is guaranteed, so that service life of components and parts in the cabinet is prolonged, and working reliability of electric appliances is guaranteed sufficiently.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a cooling and dehumidification device and a converter. Background technique [0002] At present, cooling methods of existing heat dissipation devices mainly include natural heat dissipation, forced air cooling, and cooling medium heat dissipation. [0003] Among them, since natural heat dissipation requires a spacious heat dissipation environment, it is necessary to add a larger opening area to the electrical appliance shell to reduce the protection level of the electrical appliance shell; Appropriate heat exchange fan, but when the heating power is high, it is necessary to choose a larger volume of centrifugal fan to meet the requirements of use, which increases the size and cost of the heat sink; the use of cooling media to dissipate heat can generally achieve higher The heat dissipation efficiency is high, and the heat dissipation method is simple and practical, and the re...
