Cooling device of small transformer

Abstract

The heat dissipation device comprises a transformer box body, ventilation plates, a low-voltage guide column and a high-voltage guide column, the multiple ventilation plates are fixedly connected to the front end face of the transformer box body, and a water cooling box is placed on the right side close to the transformer box body; the water cooling pipe penetrates through a gap in a heat dissipation grid on the right side of the transformer box to be connected with the water cooling box, the water inlet pipe and the backflow pipe are arranged on the left side of the top of the water cooling box, and air blowers are installed at the top ends of the two supporting plates. According to the transformer, the two rain baffles are fixedly connected to the cover plate on the top of the transformer box body, the sealing ring is arranged on the slotted hole in the cover plate, the sealing performance of the transformer box body is guaranteed, it is guaranteed that the transformer box body can normally dissipate heat and be cooled under the normal temperature condition through the arrangement of the water cooling system, and meanwhile the temperature sensor and the air blower are arranged; and when the temperature is high, the air blower is turned on through the temperature sensor for strong heat dissipation, so that the waterproof, sealing and heat dissipation capabilities of the transformer are improved.

Description

technical field [0001] The invention relates to the technical field of transformer equipment, in particular to a heat dissipation device for a small transformer. Background technique [0002] Existing small transformers refer to power transformers and audio transformers below 2,000 VA. Small transformers are suitable for circuits with a voltage of 50 to 60 Hz to 500 watts. They are usually used as machine tool control appliances or local lighting and instructions. Light power supply. [0003] However, the existing traditional small transformers generally use air-cooling heat dissipation treatment, but most of the time air cooling is difficult to meet the heat dissipation requirements of small transformers, which has a negative impact on the environmental adaptability and overload capacity of small transformers, and small transformers generally do not It has rainproof and waterproof functions, so it does not meet the existing requirements, and we propose a cooling device for...
