Abstract

The invention discloses a thermal sensitive camera heater. The thermal sensitive camera heater comprises a heating portion, a connection wire harness and a mounting frame, the heating portion is formed by a heating body and a radiator, the heating body comprises a heat conducting tube and a heating core, the heating core comprises a heating slice, an electrode slice and insulation paper, and the connection wire harness comprises a connection slice. Not fewer than two semi-circular grooves are formed in the outer lateral side of the heat conducting tube. A heat conducting face of the heat conducting tube is 0-15mm wider than the radiator. The thermal sensitive camera heater has the advantages that by the aid of the connection slice added on the electrode slice, reliable connection point contact and stable connection between the heater and the wire harness and convenience in manufacturing are achieved; by the aid of the heat conducting tube and the radiator which are different in width, the radiator can be combined with the heat conducting tube more stably and more uniform in radiation; by the aid of the semi-circular grooves in the lateral side of the heat conducting tube, the inner wall of the heat conducting tube causes less damage to a heating core insulation film, combination of the heating core in the heat conducting tube is tighter, and safety and heat efficiency are improved greatly.

Description

technical field

[0001] The invention relates to a heater, in particular to a heat-sensitive ceramic heater and a heating body and a heating core used therein. Background technique

[0002] The existing technologies mainly contain the following types:

[0003] A PTC liquid electric heater (publication number CN2612898Y), the power line is connected to the electrode and supplies power to it, and the power line is connected to the outside through the power line inlet of the metal casing.

[0004] With this technical scheme, since the power line is directly connected to the electrode, the contact resistance is large, and the connection point of the power line is likely to fall off under the action of an external force.

[0005] A PTC-heated instant electric water heater (publication number CN2742335Y), in which the wires on the electric control device are connected to the inserts on the heating device.

[0006] With this technical solution, at least the connection between...
