Description
Technical field
The present invention relates to a kind of PTC heater element field, specifically a kind of PTC heat generating device.
Background technique
The selection of radiator generally according to area depending on, be that select board-like or column radiator be often that everybody is relatively tired
Puzzled problem, no matter board-like or column radiator, heat dissipation by convection current and radiation two ways carry out.Wherein radiation dissipates
Heat is in the form of an electromagnetic wave in spatial, and spread scope is smaller.Under normal conditions, the area around the radiator in 1 meter
Domain can just experience heat radiation.And heat loss through convection is then to reach heat dissipation purpose by circulating for hot and cold air, therefore heat
Range is wider, and heat spreads more uniform.When using panel radiator, due to its design feature, suction force can produce, i.e. institute
The stack effect of meaning enhances the comfort of heat supply to increase forced convertion effect, and this point is that column radiator can not compare
Quasi-.
Existing panel radiator, unreasonable structural design, it is difficult to realize ideal working effect, and it is uneven to radiate
It is even.
Summary of the invention
Technical problem to be solved by the present invention lies in: existing panel radiator, unreasonable structural design, it is difficult to real
Now ideal working effect, and it is uneven to radiate.
In order to solve the above technical problems, the invention provides the following technical scheme:
A kind of PTC heat generating device, including PTC ceramics fever tablet, the upper and lower two sides of the PTC ceramics fever tablet are provided with thermally conductive
Sheet metal, the thermal conductive metal plate are disposed with high temperature insulation part, radiating fin lamella and cover board from inside to outside；It is described thermally conductive
Sheet metal one end is connect by connecting terminal with external power leads, is led between the thermal conductive metal plate and PTC ceramics fever tablet
Silver paste bonding agent bonding is crossed, is bonding between the cover board of connecting terminal side, it is described far from connecting terminal side
Composite plate is provided between cover board.
As a further solution of the present invention: the compound board ends are respectively arranged with groove, and the cover board is correspondingly arranged
There is convex block.
As further scheme of the invention: the high temperature insulation part passes through composite plate and extends to outside composite plate.
As further scheme of the invention: the radiating fin lamella is that the radiating fin of interlaced arrangement forms.
As further scheme of the invention: the high temperature insulation part and thermal conductive metal plate are connected by pressure viscosity mode.
As further scheme of the invention: the high temperature insulation part is heat-resistant insulating film.
Compared with prior art, the beneficial effects of the present invention are: the utility model, which leads to silver paste bonding agent, connects PTC ceramics fever tablet
And thermal conductive metal plate, guarantee the heating efficiency and thermal conductivity efficiency of PTC ceramics fever tablet；High temperature insulation part is set, can be made
Radiating fin lamella is interference-free transmits heat through portion space from inside to outside, improve heat dissipation effect.
