Problems solved by technology
The use of this PTC heater has two disadvantages: first, a narrow channel is formed between the thin aluminum end plates on both sides of the corrugated heat sink, and the wind around the PTC heater heat sink cannot pass freely, and the air volume passing through the PTC heater heat sink Limited, the wind resistance is too high, resulting in low heat dissipation efficiency; second, the PTC heater works under the condition of low wind speed and high temperature for a long time, which is prone to aging of thermal silica gel and reduced adhesive performance, which also leads to attenuation of heat dissipation efficiency
[0004] In addition to the influence of the aluminum end plate on the wind resistance, after the corrugated heat sink is joined with the rectangular tube, many cylindrical walls with a triangular cross-section are formed, which directly reduces the free wind and further reduces the heat dissipation effect

The invention discloses a PTC (positive temperature coefficient) heater and an air conditioner with the same. The PTC heater comprises a heater core and multiple cooling fins, each cooling fin is provided with a mounting groove fitting the structure of the heater core, the heater core is inserted into the mounting grooves of the cooling fins, and the cooling fins are respectively arranged on the heating core and arranged along the length direction of the heater core in a spaced manner. According to the PTC heater, the cooling fins are arranged in the length direction of the heating core in a spaced manner, each cooling fin is mounted on the heater core through the formed mounting groove, and open gaps instead of closed wall surfaces can be formed between the cooling fins and the heater core, so that cooling air volume is enlarged, and cooling effect is enhanced.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, more specifically, to a PTC heater and an air conditioner with the same. Background technique [0002] PTC (positive temperature coefficient) thermistor heater has been widely used in air conditioners as an auxiliary heating tool due to its characteristics of automatic constant temperature, self-power adjustment, high electrothermal conversion rate and no open flame. [0003] The aluminum cooling strips of traditional PTC heaters used in air conditioners are brazed together with corrugated cooling fins and aluminum end plates, and then bonded with thermally conductive silica gel and rectangular tubes for placing PTC heating elements (such as Figure 10 shown). The use of this PTC heater has two disadvantages: first, a narrow channel is formed between the thin aluminum end plates on both sides of the corrugated heat sink, and the wind around the PTC heater heat sink cannot pass fr...
