PTC heater

Abstract

The invention discloses a PTC heater. The PTC heater comprises a PTC heater body (1), and the PTC heater body (1) comprises a heat conducting body (2), a PTC heating unit (5), an end cover (6), a water inlet coupler (7) and a water outlet coupler (8), wherein the heat conducting body (2) is internally provided with at least one pipeline (3) and at least two liquid circulating channels (4); the pipeline (3) at least is arranged between two adjacent liquid circulating channels (4), and the liquid circulating channels (4) are provided with water inlets and water outlets; and the PTC heating unit(5) is arranged in the pipeline (3), and the end cover (6) is arranged on the end part of the heat conducting body (2), and is used for being connected with the water inlets and the water outlets of the adjacent liquid circulating channels (4).

Description

technical field [0001] The invention relates to a liquid heater, in particular to a PTC heater. Background technique [0002] Today's leisure sports are loved by more and more people, and there are more and more products in the market. As a new leisure and entertainment product, jacuzzi has gradually entered people's daily life. With the improvement of the quality of life, users have higher and higher functional requirements for massage bathtubs. At the same time, energy saving and emission reduction, as the primary task of all human beings in this period, require people to reduce the heat dissipation as much as possible when using thermal equipment. The existing massage bathtub electric control box mostly uses PTC heater as its heating system, but there are various defects in the existing PTC waterway system and heating body, resulting in waste, the greenhouse effect of the earth and the acceleration of the pace of life, brought about a negative impact. [0003] For exa...

AI Technical Summary

Problems solved by technology

In this utility model, the heating element is completely built in the water chamber of the heater, and the heating area of ​​the heating element is fully utilized, so it has high heating efficiency. However, for this type of PTC heater, since the heating element is completely built in In the water chamber of the heater, the heated water contains impurities such as calcium ions, so after a period of use, a large amount of scale will inevitably form on the surface of the heating body, and when thicker scale is formed, its heating efficiency will sharply increase. decline

Further, since its upper and lower sides can be made of plastic injection molding structure, after a period of use, deformation is likely to occur at the position where the upper shell 4 and the lower shell 5 contact the heating body, and finally the water in the water chamber will overflow , causing leakage
