Abstract
The utility model discloses a kind of ptc heaters of metal welding, including PTC heating element, the two sides of the PTC heating element are respectively arranged with metal electrode board, metal heat sink is respectively arranged on the outside of the metal electrode board, it is equipped with welding material of metal between the metal electrode board and metal heat sink, and passes through high-temperature soldering.The utility model is provided with metal heat sink by the two sides in metal electrode board, the thickness of metal electrode board is more than or equal to 6mil, conducive to the heat dissipation of PTC heating element, pass through welding material of metal high-temperature soldering between metal electrode board and metal heat sink, sound construction, and thermal conductivity is strong, so that the heating power of unit area PTC heating element is greater than 150W.
Description
Technical field
The utility model relates to the ptc heaters that heater technical field more particularly to a kind of metal are welded.
Background technique
Ptc heater has surface automatic constant-temperature, and the feature safer relative to other heaters is a large amount of to be applied to sky
It adjusts, in warm-air drier and liquid heating；But traditional ptc heater is mostly adhesive structure, after long-time use, due to bonded adhesives
Aging causes heater power to reply decaying, and the phenomenon that be easy to appear and fall off, fall apart；In addition traditional ptc heater unit plane
Product power is smaller (average monolithic 24*15mmPTC element power 100W or so), therefore ptc heater structure in the urgent need to address
The problem of intensity and power ascension.
Traditional ptc heater has the disadvantage that:
1, adhesive structure, glue are easy to aging
Traditional ptc heater uses adhesive structure, and after long-time use, glue is easy to aging, and heater power is caused to be decayed, and
It will appear the phenomenon that falling off, falling apart；
2, ptc heater unit area power is small
Due to being adhesive structure, the poor thermal conductivity of glue limits the performance of PTC heating power, so that ptc heater unit
Area power is small.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of structural strength height, and unit area adds
The ptc heater of the big metal welding of thermal power.
The technical solution of the utility model is as follows: a kind of ptc heater of metal welding, including PTC heating element, described
The two sides of PTC heating element are respectively arranged with metal electrode board, are respectively arranged with heat dissipation metal on the outside of the metal electrode board
Device is equipped with welding material of metal, and passes through high-temperature soldering between the metal electrode board and metal heat sink.
In the above technical solution, the welding material of metal is solid-state or liquid.
The area of the welding material of metal is less than or equal to the area of the metal electrode board.
In the above technical solution, the thickness of the metal electrode board is more than or equal to 6mil.
In the above technical solution, the power of the PTC heating element is greater than 150W.
Compared with the existing technology, the utility model has the beneficial effects that: the utility model passes through in metal electrode board
Two sides are provided with metal heat sink, and the thickness of metal electrode board is more than or equal to 6mil, conducive to the heat dissipation of PTC heating element, metal
By welding material of metal high-temperature soldering, sound construction between electrode plate and metal heat sink, and thermal conductivity is strong, so that unit plane
The heating power of product PTC heating element is greater than 150W.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the ptc heater of metal welding of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to FIG. 1, a kind of ptc heater of metal welding provided by the utility model, including PTC heating element 1, institute
The two sides for stating PTC heating element 1 are respectively arranged with metal electrode board 2, and the outside of the metal electrode board 2 is respectively arranged with metal
Radiator 3 is equipped with welding material of metal 4 between the metal electrode board 2 and metal heat sink 3, will be each using fixture when implementation
Arrangement of parts is neat and steps up, and is put into kiln and carries out high-temperature soldering.
Wherein, the welding material of metal 4 can be solid-state or liquid.Its area is less than or equal to the metal electrode board
2 area.
It is more than or equal to 6mil, by being arranged in its two sides by the thickness design of the metal electrode board 2 in the present embodiment
There is metal heat sink 3, is welded between metal heat sink 3 and metal electrode board 2 by metal material 4, sound construction, and thermal conductivity
By force, the radiating rate of the interior PTC heating element 1 of unit area (24*15mm) is substantially increased, so that the power of PTC heating element 1
Greater than 150W.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
