Abstract

The utility model relates to a metal component for radiation, in particular to a radiating tube which comprises outer radiating fins and longitudinal inner radiating fins, wherein the outer radiating fins are arranged outside a tube body and are perpendicular to the tube body, and the longitudinal inner radiating fins are arranged in the tube body. Two mediums inside and outside the tube body both enlarge the contact area of the tube body, and the heat-exchanging speed by the tube body is faster. The utility model is more applicable to a cooler in a transformer, can effectively improve the heat exchange factor of the cooler, improve the durability of the transformer and achieve the energy-saving effect.

Description

Radiating tube

Technical field

The utility model relates to a kind of hardware of heat transmission.

Background technology

In the equipment of many heat exchanges, need to adopt radiating tube to carry out heat exchange, inside and outside pipe, pass to different media usually, carry out heat exchange by the temperature of medium.Existing radiating tube is and strengthens the contact area of medium and body, usually can be body outside the some radiating fins of making, even if but like this, its radiating rate still can not reach desirable effect.

The utility model content

The utility model purpose is to design a kind of body that comprises that can further improve radiating effect.

The utility model also is provided with vertical heat radiation inner fin except being provided with perpendicular to fin outside the heat radiation of body in body body.

The utility model has all increased contact area with body at the inside and outside two media of body, speed by the body heat exchange can be faster, the utility model more is applicable in the cooler of transformer, can effectively improve the coefficient of heat transfer of cooler, improve the durability of transformer, and can reach energy-conservation effect.

Vertical heat radiation inner fin of the present utility model can spirally be arranged, to strengthen the flowability of medium in body, accelerates heat exchange.

For just with being connected of body and other parts, body of the present utility model two ends also are respectively arranged with pipe joint.

In order to make full use of the heat exchange of pipe joint and medium, the utility model also is provided with the fin with the continued access of heat radiation inner fin in pipe joint.
