The invention of the utility model aims to: to the problem that above-mentioned exists, provide a PTC heat-generating body fixing device, the utility model discloses simple to operate, it is firm reliable.
The utility model adopts the technical scheme as follows:
a PTC heating element fixing device comprises a shell, wherein an installation groove is formed in the shell, and a clamping strip is arranged in the installation groove; the mounting groove is used for accommodating the PTC heating element, and the clamping strip is used for supporting the PTC heating element.
Further, the mounting groove is a hollow mounting groove; the hollow structure is beneficial to heat exchange and heat dissipation.
Furthermore, one side of the shell is provided with an inclined plane facing the mounting groove, and the other side opposite to the inclined plane is also provided with an inclined plane facing the mounting groove; when the inclined plane is arranged for heat dissipation, a heat dissipation rotational flow can be formed, and heat can be dissipated more easily.
Furthermore, each inclined plane is provided with a clamping groove for mounting a fixing sheet; the PTC heating element is fixed in the mounting groove by using a fixing piece.
Furthermore, the fixing piece is a strip-shaped elastic pressing piece.
Furthermore, two clamping grooves are formed in each inclined plane, and the stability is better.
Furthermore, the fixing piece is connected with the clamping groove through a screw, so that the installation and the disassembly are convenient.
Furthermore, a wiring groove is formed in one side edge of the shell, which is adjacent to the inclined plane; the arrangement of the wiring groove facilitates the outgoing line of the PTC heating body to pass through the wiring groove, and is convenient and attractive.
Furthermore, a temperature sensor mounting hole is formed in the side edge provided with the wiring groove; a temperature sensor can be arranged, so that the temperature of the PTC heating body can be monitored conveniently.
Furthermore, set up the screw on the side that sets up the trough for fixed ground wire.
Further, a fan mounting hole is formed in the shell; a fan can be installed to assist in the dissipation of heat.
Furthermore, the shell is an aluminum alloy shell, and the aluminum alloy has good heat resistance and heat conductivity and high strength.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the installation is convenient, firm and reliable, and heat dissipation is facilitated.
