Abstract
The utility model discloses a device for cooling a box body of a pitch system. The device comprises a semiconductor refrigeration sheet which is arranged on the box body and is connected with a direct current power supply in the box body, wherein the cold end of the semiconductor refrigeration sheet faces the inner part of the box body, and the hot end of the semiconductor refrigeration sheet faces the outer part of the box body. By arranging the semiconductor refrigeration sheet on the box body of the pitch system, the box body can be cooled under the conditions that a special box body material is not required to be used, and holes are not required to be formed in the sealed box body.
Description
Technical field
The utility model relates to a kind of heat abstractor, relates to the heat abstractor on a kind of pitch-controlled system casing that is applied to wind-driven generator specifically.
Background technology
Electric power is indispensable form of energy in daily production and the life.Traditional thermal power generation not only will consume a large amount of fossil resources, and can discharge a large amount of greenhouse gas; Though nuclear energy power generation is emission greenhouse gas not, danger very in case accident occurs, will cause irreversible destruction to environment, so various countries are the clean energy resource of representative greatly developing with the wind power generation all in recent years.
Pitch-controlled system is the vitals in the complete blower; Its effect is the rotating speed of angle with the change blade that facing the wind through adjustment blower fan blade; Can optimize the generating efficiency of complete blower at ordinary times; If blower fan generation part fault or ambient wind velocity are too fast, it can utilize the stall principle to make the blower fan blade arrive feather position again and stop operating, thereby avoids complete blower stall to collapse.Critical pieces such as the motor driver of pitch-controlled system, back-up source all are installed in the casing separately; But because pitch-controlled system may be worked under hot environment sometimes; And its internal components also can distribute heat in the process of work, therefore need carry out necessary radiating treatment to the casing of pitch-controlled system.
In the prior art, normally adopt the heat radiation of casing body perhaps to reduce spin manifold temperature through the mode of fan heat radiation.But adopt the mode of casing body heat radiation that tank material is had relatively high expectations, not only radiating effect is bad, but also extra increase the cost of casing; Adopt the mode of fan heat radiation need perforate on casing; Though radiating effect is better; But sealing is poor, sucks dust in the casing easily, though can improve through the method that increases filter screen; But filter screen needs often to clean, otherwise filter screen is stopped up and blocking-up heat radiation wind path by dust easily.
The utility model content
The utility model technical problem to be solved just provides a kind of heat abstractor that can dispel the heat for the pitch-controlled system casing of sealing.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of pitch-controlled system casing heat abstractor, this device comprise be installed on the casing with casing in the semiconductor chilling plate that is connected of DC power supply, wherein the cold junction of semiconductor chilling plate is towards box house, the hot junction is outside towards casing.
Further, semiconductor chilling plate links to each other with DC power supply through temperature relay, and wherein temperature relay is a normally opened contact, but in temperature its contact of closure during more than or equal to a certain temperature.
Further, described closed temperature is more than or equal to 25 ℃.
Further, outside the cold junction of semiconductor chilling plate and hot junction, all post fin.
Further, between semiconductor chilling plate and fin, be coated with heat conductive silica gel.
Further, on the described fin that is attached to the semiconductor chilling plate cold junction internal fan is installed, is attached on the fin in semiconductor chilling plate hot junction external fan is installed.
Further, described internal fan is blown to fin, and described external fan is to the outside air-supply of casing.
The beneficial effect of the utility model is:
The utility model discloses a kind of pitch-controlled system casing heat abstractor; This heat abstractor is through installing semiconductor chilling plate on the casing of pitch-controlled system; Neither need use special tank material, also need not perforate on the casing of sealing, just can realize the casing heat radiation.
Through increasing temperature relay, can select the start-up temperature of semiconductor chilling plate flexibly, heat abstractor is moved under suitable situation.
Through increasing fin, heat conductive silica gel and interior external fan, can further improve the heat-sinking capability of semiconductor chilling plate, optimize the radiating effect of this heat abstractor.
