Abstract

The invention discloses a high-pressure resistant PTC heater and a production process thereof. The high-pressure resistant PTC heater comprises a first heating pipe, a second heating pipe, a left endcover and a right end cover, the first heating pipe and the second heating pipe are arranged in parallel from top to bottom, the two ends of the first heating pipe are respectively fixedly installed with the left end cover and the right end cover, the two ends of the second heating pipe are respectively fixedly installed with the left end cover and the right end cover; the middle portions of the left end cover and the right end cover are both provided with through holes, a gap is arranged between the first heating pipe and the second heating pipe, and the through holes and the gap are mutuallymatched and communicate to form a heating flow channel. The high-pressure resistant PTC heater and the production process thereof designed in the invention are reasonable in structure design, convenient and rapid in process operation, can effectively achieve the preparation processing for a PTC heater, effectively improve the heat conduction efficiency of the PTC heater, greatly improve the high-pressure resistant performance of the PTC heater and have high practicability.

Description

Technical field [0001] The invention relates to the technical field of heater processing, in particular to a high-pressure resistant PTC heater and a production process. Background technique [0002] PTC heater is also called PTC heating element. It is composed of PTC ceramic heating element and aluminum tube. This type of PTC heater has the advantages of small thermal resistance and high heat exchange efficiency. It is an electric heater with automatic constant temperature and power saving. The outstanding feature lies in the safety performance. In any application, the phenomenon of "redness" on the surface of electric heating tube heaters will not occur, which may cause burns, fires and other safety hazards. [0003] Nowadays, the heating sheet of the PTC heater is prone to uneven grain size and poor withstand voltage performance. At the same time, the thermal conductivity of the PTC heater is poor, which brings us great inconvenience. [0004] In response to the above problems, w...
