Abstract
The utility model relates to a resistance heater with positive temperature coefficients, which is provided with a plurality of resistance sheets with positive temperature coefficients. The two opposite flanks of each resistance sheet are respectively provided with an electrode side. A plurality of heat radiating fins are made of thin metal sheets and are bended to form a wave shape with a plurality of wave crests. The adjacent wave crests of one side of each heat radiating fin is stuck on one electrode side of each resistance sheet by adhesive. One plate side of a plurality of long metal plates and the adjacent wave crests of the other side of each heat radiating fin are stuck together.
Description
The utility model is with relevant with electro-heat equipment, particularly about a kind of positive temperature coefficient resistor electro-heat equipment.
In No. 92200784.5 patent case of China, disclose the ceramic Hot-air fan device that a kind of improvement is arranged, it is characterized by at upper and lower aluminium flake and weld fin with Al filler, and make its fin the cambered surface apical margin can with upper and lower aluminium flake conducting, descend the side of aluminium flake again, direct and plane positive temperature coefficient resistor (PRC) potsherd gummed with electric silica gel.
This kind device is owing to be gripped with aluminium flake between the electric cylinder of the cambered surface apical margin of fin and positive temperature coefficient resistor potsherd, so electrical conductance is not good, and thermal impedance is also high.
Main purpose of the present utility model is promptly providing a kind of positive temperature coefficient resistor electro-heat equipment of improvement, and it can be overcome the aforementioned shortcoming of commonly using electro-heat equipment.
Another purpose of the present utility model is then providing a kind of positive temperature coefficient resistor electro-heat equipment, and it is lower than traditional on manufacturing cost.
So for reaching aforementioned purpose, the utility model positive temperature coefficient resistor electro-heat equipment includes at least one positive temperature coefficient resistor sheet, respectively is provided with an electrode surface in its opposite both sides; Be bent into some radiating fins with most crests by sheet metal, respectively this radiating fin is that each adjacent peaks mat sticker with the one side amplexiforms on the electric post sheet of this resistor disc, and a long metal sheet, be fixed together with one plate face and each adjacent peaks of this radiating fin opposite side respectively.By this, each fin is directly to contact with resistor disc, is to have preferable electrically conducting and lower thermal impedance.
To be described further according to two preferred embodiments of the present utility model and conjunction with figs. below, wherein:
Fig. 1 is the stereogram of the utility model preferred embodiment.
Fig. 2 is the utility model one preferred embodiment cutaway view on the 2-2 direction in Fig. 1.
Shown in each figure, a preferred embodiment of the utility model positive temperature coefficient resistor electro-heat equipment is by 10, two groups of radiating fins 20 of four positive temperature coefficient resistor sheets, and four laths of metals 30 constitute.
Each positive temperature coefficient resistor sheet 10 has a body 12 of being made by ceramic material, and the opposite two side faces of this body 12 respectively adheres to the layer of metal pole-face.
Each group heat fin 20 that looses is to be bent into by a foil to have the wavy of most crests 22 and form, and the end face 220 of each crest 22 is flat condition.
During combination, be that each resistor disc 10 is formed a line along its length direction, the smooth top 220 mat stickers (can be electric insulation glue or conducting resinl) 40 of each adjacent peaks 22 of respectively organizing radiating fin 20 1 sides are posted solid in respectively on the opposite electrode face 14,16 of each resistor disc 10, last utilize aluminium inserts and each group to loose other each adjacent peaks solid welding of side of fin 20 together with one plate face each long metal sheet 30 again.
By aforesaid explanation as can be known, electro-heat equipment of the present utility model, it respectively organizes heat radiating fin is direct and the positive temperature coefficient resistor sheet amplexiforms together, therefore comparatively do not commonly use the resistance that the person has lacked a long metal sheet on its electric path, then lack on its thermal conductance path one the thermal impedance of long metal sheet, this kind factor all can get electro-heat equipment of the present utility model and comparatively not commonly use the person and have higher heat energy output.
