Problems solved by technology

[0005] Purpose of the invention: This invention aims at the fact that the S-shaped heat sinks and trapezoidal ribs of the traditional heat dissipation strips cannot be formed and produced in batches, and it is impossible to avoid the need to make them fully fit with the solder pieces to ensure that they will not be opened or desoldered during vacuum welding. Defects such as low strength and poor welding caused by deformation and twisting of the upper and lower fixing sheets holding the corrugated strips, high manufacturing costs, easy desoldering, and poor bonding strength between heat dissipation corrugations and heat conduction sheets, provide A heat dissipation strip of a heat-generating device of a PTC heat-sensitive material

Abstract

The invention discloses a heat dissipation strip of a PTC thermosensitive material heating device, comprising a heat dissipation ripple clamped by a heat conduction flat fin and a folded edge positioning heat conduction fin, wherein the heat dissipation ripple has no less than a folded angle surface along the height direction of the heat dissipation surface, and the folded angle surface is perpendicular to the width direction of the heat dissipation ripple; The heat dissipation ripple is formed by rolling an aluminum strip through a pair of continuous gears of a gear hobbing machine. At the same time, the invention also discloses the PTC thermosensitive material heating device and the special electric appliance using the heat dissipation strip. As that heat dissipation corrugate surface ofthe invention can be designed to enable trace water droplets to accumulate and be accommodated in the folded fan surface, With the instantaneous heating of the heating device, the micro-condensate droplets are heated and volatilized immediately, thus effectively improving the service environment, enhancing the strength of the heat sink bar and PTC heater, and improving the service reliability andenvironmental protection function of the PTC heater and the electric appliance.

Description

technical field [0001] The invention belongs to the technical field of heat-sensitive ceramic manufacturing, in particular to a heat dissipation strip of a PTC heat-sensitive material heat-generating device, a heat-generating device and a special electric appliance. 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 stri...
