Abstract
The invention aims to provide a self-cooled transformer to solve the heat dissipation problem of small-sized transformers. The self-cooled transformer comprises a transformer body consisting of a first winding, a second winding and iron cores for winding the first winding and the second winding. The self-cooled transformer is characterized in that the transformer body is arranged on a PCB (Printed Circuit Board) through a bracket, and a semiconductor refrigeration piece driven by a power supply generated by the transformer body is arranged on the PCB. By adopting the semiconductor refrigeration piece and a cooling fan, the self-cooled transformer can be self-cooled through the power supply generated by the transformer so as to prevent the transformer from over-high temperature. Therefore, the self-cooled transformer has good practicability.
Description
Technical field
The invention belongs to technical field of electricity, specially refer to a kind of transformer.
Background technology
Transformer can produce a large amount of heat when work, must in time dissipate, otherwise can cause that the temperature in the transformer rises, and affects its normal operation.Therefore traditional high-power transformer all is arranged in the transformer oil, can well be dispelled the heat, but small-sized transformer is owing to the cost reason, can only rely on natural air cooledly, and radiating effect is limited.
Summary of the invention
The objective of the invention is to propose a kind of from cooling off transformer, to solve the heat dissipation problem of miniature transformer.
Transformer body from cooling off transformer and comprising that the iron core by the first winding, the second winding and reel described the first winding and described the second winding forms of the present invention, key is that described transformer body is installed on the pcb board by support, and described pcb board is provided with the semiconductor chilling plate that the power supply that produced by transformer body drives.
Semiconductor chilling plate also is thermoelectric module, is a kind of heat pump, utilize the Peltier effect of semi-conducting material, when galvanic couple that direct current is connected into by two kinds of different semi-conducting materials, can absorb respectively heat at the two ends of galvanic couple and emit heat, can realize the purpose of freezing.Transformer is the meeting out-put supply when work, can be used for driving semiconductor chilling plate and absorb heat, thereby transformer body is cooled off.
Further, also be provided with the fan that blows to transformer body on the described pcb board, to improve the gas flow rate at transformer body place, accelerate the cooling of transformer.
Transformer of the present invention is by arranging semiconductor chilling plate and cooling fan, and the power supply that can utilize transformer to produce carries out avoiding transformer temperature too high from cooling, has good practicality.
Description of drawings
Fig. 1 is the structural representation from cooling off transformer of the present invention.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the present embodiment certainly cool off the transformer body 1 that transformer comprises that the iron core by the first winding, the second winding and reel described the first winding and described the second winding forms, key is that described transformer body 1 is installed on the pcb board 3 by support 2, and described pcb board 3 is provided with the semiconductor chilling plate 4 that the power supply that produced by transformer body 1 drives.
Transformer body 1 is the meeting out-put supply when work, can be used for driving semiconductor chilling plate 4 and absorb heat, thereby transformer body 1 is cooled off.
Further, also be provided with the fan 5 that blows to transformer body 1 on the described pcb board 3, to improve the gas flow rate at transformer body 1 place, accelerate the cooling of transformer.
Claims (2)
1. one kind is cooled off transformer certainly, comprise the transformer body that the iron core by the first winding, the second winding and reel described the first winding and described the second winding forms, it is characterized in that described transformer body is installed on the pcb board by support, described pcb board is provided with the semiconductor chilling plate that the power supply that produced by transformer body drives.
2. according to claim 1 from cooling off transformer, it is characterized in that also being provided with on the described pcb board fan that blows to transformer body.
