Problems solved by technology

[0003] Due to the assembly gap between the PTC electric heater and the sheet metal end plates at the left and right ends of the evaporator, the PTC electric heater often slips when fixing screws in production, resulting in misalignment between the screw holes on the electric heater and the screw holes on the plastic end plate, which cannot To drive the screws, the position of the PTC needs to be readjusted so that it aligns with the two screw holes on the plastic end plate
The PTC electric heating with this structure is not convenient for production and installation, and reduces production efficiency

Abstract

The invention discloses a PTC electric heating device. The PTC electric heating device comprises a PTC electric heating pipe. A first insulation end and a first installation plate are arranged at the first end of the PTC electric heating pipe, wherein the first installation plate is used for installing the PTC electric heating pipe to an evaporator and is connected with the first installation end. A controller, a power line, a second insulation end, a second installation plate and an elastic module are arranged at the second end of the PTC electric heating pipe, wherein the power line is electrically connected with the controller, the second installation plate is connected with the second insulation plate, and the elastic module is arranged at the second insulation end. Due to the fact that the elastic module produces shape change springback, the PTC electric heating pipe is moved towards the first installation plate to be attached to the evaporator, the PTC electric heating pipe cannot slide, and a gap between the PTC electric heating pipe and a left end plate of the evaporator and a gap between the PTC electric heating pipe and a right end plate of the evaporator are eliminated. The PTC electric heating pipe is not prone to sliding, and the situation that the position of the PTC electric heating pipe is repeatedly adjusted due to hole displacement cannot occur. Thus, production and installation are facilitated, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of heating elements, in particular to a PTC electric heating device and an air conditioner with the PTC electric heating device. Background technique [0002] In the prior art, the step of installing the PTC electric heater to the evaporator includes: fixing the copper tube of the evaporator through sheet metal end plates arranged at both ends of the evaporator. Among them, the sheet metal end plates on both sides of the evaporator are provided with round holes on one side and card slots on the other side; after the copper tube is fixed, the evaporator is put into the automatic welding furnace to weld the elbow; after welding, the plastic end plate is installed on the welding Finally, insert one end of the PTC electric heater into the corresponding round hole in the sheet metal end plate, then put the other end of the PTC electric heater into the card slot of the sheet metal end plate, and align it with the ...
