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 sink strip of a PTC heat-sensitive material heating device, and the heat sink strip comprises a heat dissipation ripple clamped by a heat-conducting flat piece and an edge folded locating heat-conducting fin, the heat dissipation ripple simultaneously comprises a sunken face and a fanned face in altitude direction, and the sunken face and a corner folded face are perpendicular to a width direction of the heat dissipation ripple; and the heat dissipation ripple is formed by an aluminum strip being rolled and compacted through a pair continuous engaged gears of a rolling gear machine. Meanwhile, the invention also discloses a PTC heat-sensitive material heating device using the heat sink strip and a special electrical appliance. According to the heat sink stripprovided by the invention, by the design of the heat-dissipation ripple face, trace amount of water drops can be accumulated and accommodated in the sunken or corner folded face and cannot be blown away instantaneously after secondary starting up, with instantaneous heating of the heating device, trace amount of condensed water drops is immediately heated and volatilized, service environment is improved effectively, strength of the heat sink strip and a PTC heater is improved, and usage reliability and environmental-protection functions of the PTC heater and the electrical appliance are improved.

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...
