Example Embodiment

[0040] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific drawings.

[0041] Reference figure 1 , figure 2 , image 3 , A ceramic PTC heater with corrugated fins, including a heater tube 3, the heater tube 3 is provided with radiating fins, the heater tube 3 is provided with ceramic PTC heating elements, and the radiating fins include a base 1. The base 1 is set on the heater tube 3. A plurality of radiating protrusions 2 protruding upward are provided on the base 1 along the length of the heater tube 3. The radiating protrusions 2 are formed on the side of the heater tube 3. A fan-shaped structure with narrow bottom and wide top. The side surface of the heat dissipation protrusion 2 is provided with a concave-convex structure 21 along the width direction. Compared with traditional heat dissipation fins, the heat dissipatio...

Abstract

The invention relates to the technical field of heaters, in particular to a heater. The ceramic PTC heater with corrugate heat radiating fins comprises a heater pipe, the heat radiating fins are arranged on the heater pipe, the heat radiating fins comprise bases, the bases are arranged on the heater pipe, multiple heat radiating protrusions protruding upwards are arranged on the bases in the length direction of the heater pipe, and the heat radiating protrusions form multiple fan-shaped structures with the narrow lower portions and the wide upper portions on the side faces of the heater pipe. Concave-convex structures are arranged on the side faces of the heat radiating protrusions in a width direction. Due to the adoption of the technical scheme, the heat radiating fins of the heater are even in heat radiating, high in heat radiating efficiency and solid and reliable in connection with the heater pipe, the problem of loosening caused by aged mucilage glue is avoided, and the service time is longer.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to a heater. Background technique [0002] Ceramic PTC electric heaters have been widely used because of their low room temperature resistance, easy processing and low price since their inception. Ceramic PTC electric heaters have been widely used in heating and cooling air conditioners, heaters, clothes dryers, dehumidifiers, automotive air conditioners, liquid heaters, hair straighteners, curlers, coffee pots and other fields. [0003] The heat dissipation fins in the existing ceramic PTC heaters are usually strip-shaped, and their heat dissipation efficiency is low. In addition, the way of connecting the cooling fins and the heater tube is usually by glueing. Using glue will not only produce glue smell or a small amount of organic gas during the heating process of the heater, but also may loosen the cooling fins and heater tube after long-term use, reducing the service life of ...
