Integrally-controlled PTC warm air heater

Abstract

The invention relates to an integrally-controlled PTC warm air heater. The warm air heater comprises a casing, wherein a PTC heater and a controller are arranged in the casing, and a warm air port matched with the PTC heater is formed in the casing; the PTC heater comprises a fixing frame, and a plurality of sets of corrugated sheets and a plurality of sets of PTC heating cores are sequentially arranged in the fixing frame at intervals; the controller is arranged at one end of the PTC heater, and is connected with the PTC heater; and a temperature feedback assembly is arranged on one side of the PTC heater, and the temperature feedback assembly is connected with the controller. According to the embodiment, the structure of the integrally-controlled PTC warm air heater is designed, so thatthe temperature of the PTC heater is detected in real time by the temperature feedback assembly, and the working power of the PTC heater is controlled according to the temperature of the PTC heater soas to achieve the effect that heating is carried out according to user requirements; and the heating structure of the PTC heater is improved, so that the heating efficiency of the PTC heater is improved.

Description

technical field [0001] The invention relates to the technical field of heaters, in particular to an integrated control PTC warm air heater. Background technique [0002] Most heaters adopt the structure of electric heaters, especially non-industrial heaters. From the principle of electric heaters, heaters are usually divided into: 1) electromagnetic heating, such as the electromagnetic heating technology used in commonly used induction cookers; 2) infrared heating, which uses radiation heat transfer and transfers energy by electromagnetic waves. 3) Resistance heating, that is, using electric current to emit heat through the electric heating body for heating. Resistance heating is usually achieved by means of resistance wire heating, ceramic heating, resistance coil heating, and quartz tube heating. [0003] In general, an air conditioning system for a vehicle includes a main body in which an evaporator, a heater, etc. are installed, a blower fan, and a blower case installe...

AI Technical Summary

Problems solved by technology

The current fuel vehicles use the engine heat source as the heat source of the car air conditioner and warm air; while the heat generated by the motor of the electric car is very small, which cannot meet the needs of the car air conditioner and warm air; an independent electric heater needs to be added
