Abstract
The utility model relates to a PTC heating assembly for quilt warmers, which makes a PTC element 1 solidified between a double-corrugated heat dissipation stripe 3 and a single-corrugated heat dissipation stripe 2 in high temperature; one end of the outer frame 2-1 of the single-corrugated heat dissipation stripe 2 and one end of a core plate 3-2 of the double-corrugated heat dissipation stripe 3 are respectively riveted with a single terminal 4 by copper rivets according to the order of the single-corrugated heat dissipation stripe 2, the PTC element 1, the double-corrugated heat dissipation stripe 3, the PTC element 1, the single-corrugated heat dissipation stripe 2. When heats, the PTC heating assembly does not consume indoor oxygen and has the advantages of long service life, high electrothermal conversion efficiency and obvious power saving; because the PTC element is heated by automatically limiting temperature; thus, disaster outcomes such as, the softening of plastic elements in the machine, deformation or burning by dry cloths, etc. which are caused by excess temperature can be avoided effectively, and the utility model is very safe.
Description
The utility model belongs to a kind of novel heater, is specifically related to a kind of PTC heating component that is used for Guilt warming machine.
The early spring bed clothes humidity, winter bed clothes cold, many producers developed be used to dry, the Guilt warming machine of warming by fire bed clothes, these Guilt warming machines generally adopt the heating of heating wire or electrothermal tube.Adopt heating wire or electrothermal tube as pyrotoxin, electric heating conversion efficiency is low, and power consumption is big; Easily oxidation of surface consumes the oxygen in the room air, and useful life is low; Because can not be from limit temperature, catastrophic effects such as fire hazardous.
The purpose of this utility model is to provide a kind of resistance wire or the novel heater of electrothermal tube--PTC heating component that is used for substituting Guilt warming machine heating usefulness.
PTC heating component of the present utility model, it is characterized in that wall scroll ripple heat sink strip, the PTC element, two bar ripple heat sink strips, the PTC element, the order of wall scroll ripple heat sink strip, with silicon rubber with the PTC element fixedly connected and hot setting between two bar ripple heat sink strips and wall scroll ripple heat sink strip, an end of central layer is respectively riveted a single terminal not by copper rivet in the outer rim of wall scroll ripple heat sink strip and two bar ripple heat sink strips, described pair of bar ripple heat sink strip comprises that a thickness of slab is the half-hard state single face vacuum brazing clad aluminium frame of 0.45～0.9mm, and thickness of slab is a central layer in the two-sided vacuum brazing clad aluminium of half-hard state of 0.45～0.9mm, the thickness of slab that the vacuum hot weld has the annealed state aluminium alloy to be made in the middle of above-mentioned frame and middle central layer is the radiatinig corrugated of 0.15～0.4mm, and its ripple density is that two adjacent wave line centre-to-centre spacing r are 1.3～6.0mm; Described wall scroll ripple heat sink strip is to be that the thickness of slab that the vacuum hot weld has the annealed state aluminium alloy to be made between the half-hard state single face vacuum brazing clad aluminium outer rim of 0.45～0.8mm and the interior frame is the radiatinig corrugated of 0.15～0.4mm at a thickness of slab, and its ripple density is that two adjacent wave line centre-to-centre spacing r are 1.3～6.0mm; Described PTC element is that a kind of Curie temperature is that 180～270 ℃, thickness are the BaTiO of 1.8～3.8mm
3Base thermal sensitive ceramics resistance.
Described PTC element is a kind of semistor.
The width of PTC element should with the heat sink strip size match; The integer multiple of its length be slightly less than heat radiation band corrugated portion length (1.0～2.0mm), its quantity heats power requirement according to machine and decides.
The watt level of PTC heating component is relevant with ripple density with the seal ring thickness of thickness, Curie temperature and the heat sink strip of PTC element.Generally, the Curie temperature of PTC element is high more or reduce the thickness of PTC element, and the power of this PTC element is just big; Increase the ripple density of heat sink strip or reduce the seal ring thickness of heat sink strip, also can improve the heating power of PTC heating component.As shown in the table, the seal ring thickness of the thickness of choose reasonable PTC element, Curie temperature and heat sink strip and ripple density just can obtain the PTC heating component of the good power demand of fail safe.
