Embodiment 1

[0017] Such as figure 1 It is an embodiment of the present invention, and it can be seen from the accompanying drawings that the present invention is a dehumidification method and device for a converter device or equipment of a wind power generation system, which utilizes the liquid cooling circulation system of the converter device or equipment itself To achieve the desired dehumidification effect; the flow device to be dried or the equipment itself has a liquid cooling circulation system, connect the air / liquid heat exchanger of the dehumidifier and the surface to be cooled to the liquid cooling circulation system of the flow device The dry liquid circulation system and the device for collecting and discharging condensed water make full use of the heat exchanger of the cooling liquid circulation system of the large-scale inverter for dehumidification treatment.

[0018] Specifically, the described dehumidification treatment is to set a cooling element group or a cooling pipe...

Embodiment 2

[0032] Such as figure 2 It is another embodiment of the present invention. It can be seen from the accompanying drawings that the present invention is a dehumidification method and system applied to those small and medium-sized converters (i.e. utilizing air-cooled converters). The dehumidification method and system The main body is basically the same as that described in Embodiment 1. The difference is that the drying system has a liquid pump 206 and a heat exchanger 207 because the inverter device does not have a liquid cooling circulation system, and these two are arranged outside the chassis 202, while the exchanger of the air dehumidifier 213 and the waiting A set of cooling surfaces 201 and a dry liquid circulation system 204 are provided inside the chassis. The heat released by the converter 203 during operation can increase the temperature, and the dry surface of the air dehumidifier 213 is cooled to a relatively low temperature to form a temperature difference to ac...

Abstract

The invention relates to a dehumidifying method and a dehumidifying system of a wind power generation system converter device or equipment, which realize the dehumidifying effect to be achieved by a liquid cooling cyclic system carried by the converter device or equipment; the converter device or equipment to be dried is provided with the liquid cooling cyclic system, an air / liquid heat exchangerof a dehumidifier and a surface to be cooled are connected to a dry liquid cyclic system of the liquid cooling cyclic system of the converter and a device for collecting and discharging condensed water, and the heat exchanger of the cooling water cyclic system of the large converter is fully utilized for the dehumidification of the dehumidifier. The air dehumidifier comprises at least one air / liquid heat exchanger and a surface to be cooled thereof, and is provided with the dry liquid cyclic system connected with the liquid cooling cyclic system of the converter and the device for collecting and discharging the condensed water. The invention takes full advantage of the cooling liquid cyclic system of the large converter so as to reduce energy consumption to a minimum level.

Description

technical field [0001] The present invention relates to a dehumidification method and device for equipment, in particular to an air dehumidification method and an air dehumidification system for a converter device of a wind power generation system. The air dehumidifier of the air dehumidification system includes at least one air / liquid heat exchanger and Its surface to be cooled, and use the original liquid cooling system and heating device of the converter as the basis. When the surface is cooled and the internal temperature of the converter is relatively high or possibly heated, moisture condenses on the surface, whereby the air dehumidifier is located inside the converter enclosure. Background technique [0002] Converter equipment or devices are used in various industrial fields such as large wind turbines, offshore drilling, ships, locomotives, aviation equipment, etc. Many of these devices operate in complex climate environments and harsh weather environments, as well...
