Abstract
The utility model discloses a single-sided electrode leading PTC constant temperature heating element, which comprises a heating resistor body, two splitted metal conductive layers (namely a first metal conductive layer and a second metal conductive layer) attached to one surface of the heating resistor body, a third metal conductive layer attached to the other surface of the heating resistor body, and a fourth metal conductive layer for connecting the first metal conductive layer and the third metal conductive layer. The second metal conductive layer, the heating resistor body and the third metal conductive layer form a constant temperature heating unit. The third metal conductive layer is connected on the first metal conductive layer through the fourth metal conductive layer such that the third metal conductive layer, the fourth metal conductive layer and the first metal conductive layer form an integrated conductive layer. A power wire is led out from the same surface of the first metal conductive layer and the second metal conductive layer so as to let the third metal conductive layer contact with a heat conductor and transfer the heat. By the adoption of the PTC constant temperature heating element, heat transfer efficiency can be greatly raised, thermal utilization efficiency is improved, and it is beneficial to energy conservation.
Description
Technical field
The utility model relates to the architecture advances that a kind of single-side electrode is drawn type PTC constant-temperature heating element.
Background technology
Traditional PTC constant-temperature heating element is a kind of heating element commonly used, be by heating resistor, consist of with the metal conducting layer that is attached to heating resistor two opposites, power lead is drawn from the metal conducting layer on two opposites respectively, and the outbound course of power lead has two kinds: a kind of is to contact respectively two metal conducting layers on opposite with two sheet metals; Another kind is with two wire bonds (or bonding), two metal conducting layers over there, however the first method complex structure, volume is large, and wiring is also inconvenient; Second method makes all out-of-flatnesses of metal conducting layer upper and lower surface, thereby makes the metal conducting layer can not be fully and the heat carrier close contact, causes heat transfer efficiency low, is unfavorable for energy savings.
The utility model content
The purpose of this utility model is to overcome defects of the prior art, provides a kind of and can improve heat transfer efficiency, improves heat utilization efficiency, is conducive to energy savings, and the convenient single-side electrode of installing is drawn type PTC constant-temperature heating element.
for achieving the above object, the technical scheme that the utility model provides is as follows: provide a kind of single-side electrode to draw type PTC constant-temperature heating element, comprise heating resistor, also comprise and be attached to lip-deep the first metal conducting layer of heating resistor one and the second metal conducting layer, be attached to another lip-deep the 3rd metal conducting layer of heating resistor, and be attached to the 4th metal conducting layer on heating resistor one side surface, the 4th metal conducting layer one end is connected with the first metal conducting layer, the other end is connected with the 3rd metal conducting layer, described the second metal conducting layer, heating resistor and the 3rd metal conducting layer form a heated at constant temperature unit, described the 3rd metal conducting layer is connected on the first metal conducting layer by the 4th metal conducting layer, make the 3rd metal conducting layer, the 4th metal conducting layer and the first metal conducting layer form a monolithic conductive layer.
Two power leads are drawn from the first metal conducting layer and the second metal conducting layer same surface respectively.
The beneficial effect that single-side electrode described in the utility model is drawn type PTC constant-temperature heating element is: by described power lead is drawn from the first metal conducting layer and the second metal conducting layer respectively, because power lead is to draw from the same surface of PTC constant-temperature heating element, make the 3rd metal conducting layer can be fully and the heat carrier close contact, heat is conducted, can improve greatly the heat transfer efficiency of heat carrier, has heat transfer efficiency high, heat utilization efficiency is high, advantage easy for installation is conducive to energy savings.
Below in conjunction with drawings and Examples, single-side electrode described in the utility model being drawn type PTC constant-temperature heating element is described further.
