AI Technical Summary

Technical Problem

Conventional axial thermal fuses have a small contact area with the heating element, resulting in slow heat transfer and an inability to respond and cut off the circuit in a timely manner, posing a safety hazard.

Method used

A high heat transfer and fast response temperature fuse is designed. The main body of the heat-conducting component is attached to the periphery of the fuse housing, and fins are set at both ends to contact the surface of the heat-generating component, thereby increasing the contact area and accelerating heat transfer by using the heat-conducting component and fins.

Benefits of technology

By increasing the contact area, the response rate of the thermal fuse is improved, ensuring that the circuit can be cut off in time when the heating component overheats abnormally, thus enhancing safety.

Abstract

The utility model relates to fuse technology field especially relates to a high heat transfer quick response temperature fuse. The high heat transfer quick response temperature fuse includes temperature fuse body and heat conduction spare, and the main part of heat conduction spare is pasted around the shell peripheral surface of temperature fuse body, the first wing piece of the first end of main part is equipped with the direction of extending away from temperature fuse body, and / or, the second wing piece of the tail end of main part is equipped with the direction of extending away from temperature fuse body, the first wing piece and second wing piece are used for with the surface contact of heating component. When installing the temperature fuse, the main part of heat conduction spare is pasted in the fuse main part periphery, and the wing piece can be pasted on the surface of heating component to expand the contact area of temperature fuse and heating component, which is favorable to the heat of heating component to accelerate transmission to temperature fuse, thereby improving the response rate of temperature fuse.
