ptc heater for air conditioner

Abstract

A PTC heater for an air conditioner belongs to the technical field of electric heaters. Including the PTC heater body, there are more than two parallel to each other and spaced apart from each other; the tailstock has a tailstock socket cavity on the tailstock; the electrical connection seat has an electrical connection socket socket cavity; The connecting seat is buckled and fixed, and features: there is a tailstock support on the tailstock, and the tailstock support has a tailstock support cavity; the left end surface of the front and rear walls of the electrical connection seat is extended with a support, and the support has a support cavity. There is an electrode sheet insulating partition wall in the socket cavity of the electrical connection seat, and the right side of the electrode sheet insulating partition wall is joined to the right wall of the electrical connection seat of the electrical connection seat, and is located between the electrode sheet insulating partition walls in two adjacent electrical connection seat cavities The space constituted as an electrical protection component housing cavity. Good heat dissipation efficiency and effect; prevent cracking, deformation and premature aging of tailstock and electrical connection seat; meet installation requirements; save material consumption and increase assembly speed.

Description

technical field [0001] The invention belongs to the technical field of electric heaters, and in particular relates to a PTC heater for an air conditioner. Background technique [0002] The aforementioned PTC heater is also called a PTC heater or a PTC heating device, and PTC is an English abbreviation (English full name: Positive Temperature Coefficient). The PTC heater is composed of the following three parts: one is the PTC heater body, which is also called the PTC radiator body; the second is the tailstock; the third is the electrical connection seat. One end of the PTC heater body is fixed to the tailstock, and the other end is fixed to the electrical connection seat, and the PTC heater body includes an aluminum tube, and a corrugated radiator positioned on one side of the length direction of the aluminum tube or on the corresponding two sides. The aluminum sheet and the PTC heating core accommodated in the aluminum lumen of the aluminum tube, wherein the PTC heating co...

AI Technical Summary

Problems solved by technology

[0005] However, disposing two or more PTC heaters to the air conditioner in a simple way of duplication will produce the following technical problems: because if the number of tailstocks and electrical connectors is combined with the number of PTC heater bodies To maintain a step-by-step relationship, specifically, when there are two PTC heater bodies, if two tailstocks and two electrical connection seats are used, the following technical problems will undoubtedly occur: First, due to the multiplied number of parts , which is not conducive to manufacturing and assembly; second, due to the increase in the number of parts, it will be limited by the limited space in the indoor unit, and even interfere with other components; third, it is not conducive to saving resources and reflecting the economy. sex

But this CN104053255A still has the following four shortcomings: one, although the tailstock socket cavity of the tailstock and the electrical connector socket socket cavity of the electrical connector seat can play a supporting role to the left end and the right end of the PTC heater, they enter into the A short section of the left end and right end of the PTC heater body in the socket cavity of the tailstock and the socket cavity of the electrical connection seat is in a confiscated state by the tailstock and the electrical connection seat, so the PTC heater body can function effectively The length is affected by the confiscation of a part by the tailstock and the electrical connection seat
