Description
Technical field
The invention belongs to electronic component manufacturing technology fields, and in particular to a kind of general PTC liquid heater.
Background technology
Currently, PTC ceramics be widely used in as emerging heating source white domestic appliances, Integral ceiling, automobile,
The every field such as kitchen appliance, have that decaying is slow, the operation is stable, does not generate the good characteristics such as open fire.But some specific areas, such as
It is difficult to be processed with traditional PTC heating cores that submersible liquid, which heats or has the place of particular/special requirement to mounting structure and installation space,
The heater of method manufacture is installed, these local requirements heater installation methods and shape will be close to traditional heating wire
Heating tube, but heating properties wish to reach PTC ceramics heat levels again, and it is therefore necessary to develop a kind of shape and traditional heating wire
The close PTC ceramics heater of heating tube.Has similar heater on the market at present, but inside is used using sheet PTC ceramics
Magnesia powder is filled, these products are brought while solving shape and heating properties in PTC ceramics breakdown ratio
The fatal bad phenomenon risen.
Invention content
Technical problem to be solved by the invention is to provide a kind of general PTC liquid heaters, for adding for general liquid
Heat, have the characteristics that long lifespan, attenuation rate bottom, can with dry combustion method, be easily installed, breakdown rate it is low.
The technical proposal for solving the technical problem of the invention is：A kind of general PTC liquid heater, including circular tube shaped
Metal shell, PTC heat generating cores and sealing flange, one end welded seal that the metal shell is contacted with water, the other end installation
Sealing flange；The PTC heat generating cores are set in metal shell, the PTC heat generating cores include PTC heater elements, electrode slice and
Insulating film, the PTC heater elements are formed in parallel by the PTC ceramics piece of one or more pieces special-purpose high temperatures, high voltage, the PTC
Potsherd two sides are with heat conductive silica gel bonding electrode slice, connecting wire or connector on the wire interconnecting piece of the electrode slice,
Insulating film is wrapped up outside the electrode slice, the insulating film both sides are respectively equipped with heat conduction item, and the heat conduction item is that aluminum is semicircle
Strip, is combined into cylindric with PTC heat generating cores, and size is matched with metal shell internal diameter.
As a preferred embodiment, the metal shell is stainless steel, used between the metal shell and sealing flange
High-temperature-resistant epoxy resin seals.
As a further improvement, the arcwall face of the heat conduction item is equipped with card slot, for riveting ground wire.
The length and diameter of the present invention can be customized according to different needs.
The beneficial effects of the invention are as follows:Design is scientific and reasonable, and good appearance is easy to use, and automatic constant-temperature-heating does not produce
Raw open fire is suitble to the use in various submersible liquid heating place, have long lifespan, attenuation rate bottom, can with dry combustion method, convenient for peace
The low feature of dress, breakdown rate.
Description of the drawings
Fig. 1 is the structural schematic diagram one of the embodiment of the present invention.
Fig. 2 is the structural schematic diagram two of the embodiment of the present invention.
The present invention will be further described below in conjunction with the accompanying drawings.
Specific implementation mode
As shown in attached drawing 1, Fig. 2, a kind of general PTC liquid heater, including the stainless steel casing 1 of circular tube shaped, PTC fever
Core and sealing flange 3, one end welded seal that the stainless steel casing 1 is contacted with water, the other end install sealing flange, Sealing Method
Orchid be stainless steel material, outside be equipped with sealing ring 10, screw-socket and outer-hexagonal nut 2, internal openings, opening diameter with it is required
Outer diameter after the metal shell draw matches；It is sealed using high-temperature-resistant epoxy resin between 1 sealing flange of the stainless steel casing.
The PTC heat generating cores 2 are set in stainless steel casing 1, the PTC heat generating cores 2 include PTC heater elements 4, electrode slice 5 and absolutely
Velum 6, the PTC heater elements 4 are formed in parallel by the PTC ceramics piece of one or more pieces special-purpose high temperatures, high voltage, the PTC
Potsherd two sides bond electrode slice 5 with heat conductive silica gel, and connector 8 is connected on the wire interconnecting piece of the electrode slice 5, described
Insulating film 6 is wrapped up in 5 outside of electrode slice, and 6 both sides of the insulating film are respectively equipped with heat conduction item 7, and the heat conduction item 7 is that aluminum is semicircle
Strip, is combined into cylindric with PTC heat generating cores 2, and size is matched with 1 internal diameter of stainless steel casing.The arc of the heat conduction item 7
Shape face is equipped with card slot, for riveting ground wire 9.
The present invention assembling process be：If dry plate PTC heating elements are arranged side by side, both sides heat conductive silica gel binding metal material
The electrode slice of matter, welds connector on the wire interconnecting piece of electrode slice, and outside package insulating film forms PTC heat generating cores, will wrap
The upper heat conduction item of PTC heat generating cores two sides folder for wrapping up in insulating film is filled in metal shell together.It fills in and uses respective model afterwards in place
Draw wheel carries out the draw on machine for shrinking.It is general that internal each component is required to compress mutually, and PTC ceramics piece is without comminuted breakage.
