Description

A kind of corrugated heating element

Technical field

The utility model relates to a kind of corrugated heating element.

Background technology

The use of corrugated heating element is very extensive, and especially the scope of application as the fan type heating element is more extensive in the electric equipment products of family expenses and similar applications and equipment.Existing corrugated heating element, fan type PTC heater for example, its heater is exactly a heater element, by making the corrugated heating element on the surface of heater element with the method for the bonding corrugated heat sink strip of making by vacuum brazing method of silicon rubber.Heater for the surface insulation type, surface at heater element is provided with conductive electrode and insulating barrier successively, form the tubular type insulation heating body after cladding the heat conduction aluminum pipe again, be bonded with the corrugated heating element that the corrugated heat sink strip of making by vacuum brazing method is made the surface insulation type on the surface of heater by silicon rubber then.

Adopt above prior art, at first need the corrugated heat sink strip (fin of being called is also arranged) of independent production vacuum brazing.Its technology is: earlier thin aluminum sheet is shaped to undulatory fin, with two thin aluminum sheets that simultaneously form brazing solder the aluminium corrugated fin is clipped in the middle again and combines, be placed on then and be heated to certain temperature in the special-purpose soldering furnace and two solder flux on the thin aluminum sheet melted fully and the corrugated fin that is clipped in the middle finished product with thin aluminum sheet formation soldering one, the oxide layer that forms by the rinsing of acid, alkali lye with when soldering is removed in clear water flushing repeatedly is made for undulatory heat sink strip finished product after the drying again.This shows, adopt the heat sink strip of above-mentioned technology manufacturing to come the undulatory fin of clamping with two aluminium sheets, and this thin aluminum sheet must have an expensive brazing solder of coated, cost is higher.In addition, when the moulding of heat sink strip, welding, to use a large amount of workers, anchor clamps and expend a large amount of solderings and burn till electric energy; After the welding one, also need to float, wash, loaded down with trivial details technology such as drying, except the certain acid of needs consumption, base material and waste great amount of water resources, also can cause bigger pollution to environment.

Summary of the invention

Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, provide a kind of simple in structure, with material economize, manufacturing process simplifies, production efficiency is higher, the corrugated heating element of low cost of manufacture, production process non-environmental-pollution.

Technical scheme: corrugated heating element described in the utility model, comprise heater and be fitted in the corrugate fin of heater both sides, it is characterized in that: be fitted with one deck conducting strip away from the one side of heater at fin.

Described conducting strip bonds together by heat-resistant silicon rubber and heater.Described heater has many groups, is fitted with described corrugated fin in the both sides of every group of heater, is provided with the described conducting strip of one deck between adjacent fin.

In order to make fin bonding with the plane of heater and conducting strip respectively with heat-resistant silicon rubber, be coated with respectively two of fin and be brushed with heat-resistant silicon rubber, one of them face directly and the plane of heater bonding, the plane of another face and conducting strip is bonding.

For the corrugated heater of surface insulation type, described heater comprises heat pipe, is heater element in the centre of heat pipe, between heater element and heat pipe inwall conductive electrode and insulating barrier is arranged.A face of described fin directly and two side bonds of heat pipe.

For the corrugated heater of surface charging type, fan type heater for example, described heater is exactly a heater element, and a face of fin directly is bonded on the plane of heater element.

By the corrugated heater that above method is made, only need behind the isothermal curing about bonding back is by 350 ℃, promptly can be made into the corrugated heater of surface insulation or surface charging.

By length and the employing modes of combination side by side of organizing that change the above single group corrugated heater, can produce the corrugated heater element of various practical lengths, width and power more.

Beneficial effect: the utility model has the advantages that:

1, simple in structure, technology is simple, cost is low.

2, for the corrugated heater of surface insulation type, a face of corrugated fin of the present utility model directly with the mutually bonding corrugated heater that promptly can be made in the plane of heat pipe.And existing Technology Need will be made the corrugated heat sink strip earlier after thin plate radiatinig corrugated and the vacuum brazing of two thin plate heat conduction aluminium flakes, again at two side bonds aluminium ripple heat sink strips of tubulose heating core body.Corrugated heater with single group is an example, adopt the vacuum brazing heat sink strip of prior art manufacturing will be with two coateds the aluminium sheet of soldering paste come the undulatory fin of clamping, cost is higher.In addition, to use a large amount of workers, anchor clamps in the moulding of heat sink strip, in welding and manufacturing and expend a large amount of solderings and burn till electric energy, after the welding one, also need to float, wash, loaded down with trivial details technology such as drying.Adopt technology of the present utility model, except using two thin plate heat conduction aluminium flakes less, also save cleaning materials such as acid, alkali.Since do not need repeatedly remove the oxidation cleaning, except saving the great amount of water resources, manufacture in the process and can not cause environmental pollution.

3, for the corrugated heater of surface charging type, fan type heater for example, the utility model also only need directly be bonded in a face of corrugated aluminium radiator fin on the plane of heater element and get final product, the aluminium sheet of soldering paste of can having saved two coateds equally.

4, because the aluminum pipe heating core body in the prior art, or the bonding corrugated heat sink strip of vacuum brazing on two heating faces of heater element, this heat sink strip up and down two all have and be used for the conducting strip of clamping heat sink strip.This shows that these two conducting strips also must increase lead, the dispel the heat loss of heater in heat transferred except that the cost that has increased product.The utility model is owing to be direct contact between the heating face of heater and the corrugated fin, and the heat of heater can be directly delivered on the radiatinig corrugated, therefore can obviously improve the efficient of electric heating conversion.
