Abstract

The invention discloses a PTC electric heater, a heating device and a method for adjusting the heating capacity of the PTC electric heater, relates to the technical field of heating, and aims to solve the technical problem that the matching success rate of the heating capacity of a PTC electric heater developed in the prior art and the heating capacity required by a heating device is relatively low. The PTC electric heater comprises support mechanisms and an electric heating mechanism; the electric heating mechanism comprises cooling fin assemblies and a heating assembly, wherein the cooling fin assemblies are installed on the two sides of the heating assembly; the support mechanisms are arranged at the two ends of the electric heating mechanism and rotationally connected with the electric heating mechanism; and ratchet wheel assemblies are arranged on the support mechanisms and used for adjusting the mounting angle of the electric heating mechanism so as to adjust the head-on wind speed of the electric heating mechanism. According to the PTC electric heater, the heating capacity of the PTC electric heater can be adjusted, the matching success rate of the heating capacity of the PTC electric heater and the heating capacity needed by the heating device is increased; and the installation space of the PTC electric heater is not limited, and the cost of the PTC electric heater is low.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a PTC electric heater, a heating device including the PTC electric heater and a method for adjusting the heating capacity of the PTC electric heater. Background technique [0002] PTC electric heater is an electric heater with automatic constant temperature and power saving. It has the advantages of small thermal resistance and high heat exchange efficiency. It will not produce "redness" on the surface of electric heating tube heaters in any application Phenomenon, can avoid fire and other safety hazards. Therefore, many heating devices now use PTC electric heaters to realize the heating function, such as air conditioners, heaters, etc. However, PTC electric heaters also have shortcomings in specific applications. Specifically, the application of electric heating tube heaters can ensure that the heating capacity of the heating device is developed at one time; while using the PT...
