Translation heat transfer type efficient heat dissipation transformer

Abstract

The invention discloses a translation heat transfer type efficient heat dissipation transformer, belongs to the field of transformers, and aims to solve the problem that in the continuous heating process of the transformer, a thermal contact bag continuously expands to recover the expansion process, so that a heat exchange translation rod is driven to continuously translate leftwards and rightwards, and the heat dissipation efficiency of the transformer is greatly improved. Compared with the prior art that heat of radiating fins is slowly dissipated outwards, the heat exchange translation rodcan continuously enter and exit from the radiating fins, so that the heat exchange translation rod can continuously gather the heat in the radiating fins and guide the heat to the outer side, and compared with the process that the heat of the radiating fins is slowly dissipated outwards in the prior art, the outward transmission and dissipation of the heat are remarkably accelerated; the heat dissipation efficiency of the transformer is effectively improved, meanwhile, through cooperation of the heat gathering rod and the heat conduction fluff, the gathering effect of the heat exchange translation rod on heat on the radiating fins can be improved when the heat exchange translation rod is located in the radiating fins, the vertical state can be kept when the heat exchange translation rod islocated outside the radiating fins, the contact area with the outside is effectively increased, and the heat dissipation effect is better.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a translational heat transfer type high-efficiency heat dissipation transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). Transformer cooling refers to dissipating the heat generated by the running transformer through certain methods. When the transformer is running, the heat generated by the loss of the winding and core must be dissipated in time to avoid insulation damage caused by overheating. For small-capacity transformers, the ratio of the outer surface area to the volume of the transformer is relatively large, and a self-cooling method can be used to dissipate heat through radiation and natural convection. The self-cooling method is suitable for indoor small transformers. In order to prevent fires, dry type...

Problems solved by technology

[0003] Existing transformers are usually equipped with heat dissipation scales on both sides of the surface, and the heat generated inside the transformer is directly conducted outward through the external heat dissipation scales. The heat dissipation scales can increase the contact area with the outside world to accelerate heat dissipation. However, in actual use, The transformer will generate a lot of heat, and the heat dissipation scales will accumulate more heat, which is difficult to dissipate in time, especially the internal heat of the heat dissipation scales, which needs to penetrate through the heat dissipation scales and then be dissipated outwards. The heat dissipation is slow, causing the transformer to Frequent overheating in summer
