Forming tool of cooling strip of PTC heat-sensitive material heating device

Abstract

The invention discloses a forming tool of a cooling strip of a PTC heat-sensitive material heating device. The forming tool is characterized by comprising a table plate for placing the cooling strip,and a positioning frame for clamping and fixing the cooling strip, the table plate is in an L shape in the width direction through machining, the surface in the width direction of the table plate is provided with a rectangular groove, at least one forming fastening cylinder is arranged on the side in the length direction of the table plate, the positioning frame is composed of two rectangular metal strips and at least two sliding fasteners, and the metal strips have the width the same as that of the cooling strip and the height of 15-50 mm. The forming tool is scientific in structural design,easy to control, high in yield and low in manufacturing cost; the clamping work of the cooling strip can be well completed, the cooling strip is clamped after being assembled and disengaged after being baked and formed, it can be ensured that no parts of the cooling strip are scattered in the whole process, and the forming tool can be conveniently controlled by operators.

Description

technical field [0001] The invention belongs to the technical field of heat-sensitive ceramic manufacturing, in particular to a molding tool for a cooling strip of a PTC heat-sensitive material heating device. Background technique [0002] Patented sealed positive temperature coefficient thermistor heater, patent number 200620034186, the corrugation is S-shaped, although it is beneficial to improve condensation, but the S-shaped heat sink and trapezoidal ribs cannot be mass-molded and produced, even if the samples are made by hand or 3D. , and it is impossible to avoid deformation, twisting and other low strength and welding due to the need to make it fully bonded to the soldering piece to ensure that it does not open or desolder during vacuum welding and pressurizes the upper and lower fixing pieces that hold the corrugated strip. bad defect. [0003] In addition, such as the patented corrugated heat dissipation strip, the patent No. 201320036750.5 discloses the use of dou...

Problems solved by technology

Because the heat dissipation surface of the heat dissipation corrugated in the prior art is a continuous plane without concave-convex structure, the condensed frost or water droplets will accumulate at the bottom along the heat generation plane, so that the heat exchange wind at the moment of the second start-up will accumulate on the heat dissipation surface. The hidden danger of water droplets blowing out on the corrugated surface, resulting in customer complaints
