Abstract

The invention belongs to the technical field of electric heater equipment, particularly relates to a metal PTC (Positive Temperature Coefficient) electric heater, and aims to solve the problems of non-uniform heat dissipation and low heat dissipation efficiency in the heat dissipation process of a heater outer frame due to the fact that a heat dissipation fan of an existing electric heater is fixedly arranged. According to the scheme, the electric heater comprises a shell, and a plurality of electric heater bodies are fixedly installed in the shell. A plurality of cooling fins are fixedly installed on the two sides of each electric heater body, two vertical plates are fixedly installed on one side of the shell, the sides, close to each other, of the two vertical plates are fixedly connected with the same connecting shaft, and the outer side of the connecting shaft is rotationally sleeved with a sleeve. A motor and a transverse plate are fixedly installed on the side, close to the shell, of the sleeve, and one end of a worm is fixedly connected to an output shaft of the motor. The electric heater is reasonable in structural design, the cooling fan blades are driven to rotate and swing at the same time, so that waste heat in the shell of the electric heater is quickly blown away, and the service life of the electric heater is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric heater equipment, in particular to a metal PTC electric heater. Background technique [0002] The PTC electric heater has the characteristic of constant temperature heating. The principle is that after the PTC heating plate is powered on, the self-heating temperature rises and the resistance value rises into the transition zone. The surface temperature of the PTC heating plate will maintain a constant value. The internal temperature is related to the external voltage, but has nothing to do with the ambient temperature. It is widely used in household air conditioners; even in abnormal working conditions, due to the adjustment function of the PTC element itself, the input power can be reduced very low, still There will be no accidents. Existing PTC electric heaters generally include multiple PTC heating sheets, the upper and lower sides of the PTC heating sheets are covered with electrodes, and ar...
