Abstract
The utility model provides a radiation component of the electric heater, which comprises a wing shape radiation piece (1) provided with a centre cavity (11), a metal material inserted in the cavity (11), and outer wall of the metal material is pressed closely to inner wall of the centre cavity (11), the metal material is equipped with at least one centre cavity (22) which can be inserted with an electric heating component. The metal material is compose of two pairing sub materials (2) whose, the joint (21) of the sub materials is connected as a whole in the element rest to groove method; for easy producing, the two sub materials (2) should better have completely the same shape and size. The wing shape radiation piece (1) can be a whole, as well be formed by outside joint of a plurality of metal materials in axis direction, now, the metal material outer wall and the centre cavity (11)of the wing shape radiation piece can be positioned in the convexo and concave in axis direction. Compared to the prior art, the utility model has advantages that thanks to adding a middle heat conduct metal material between the electric heating component and the radiation piece, the utility model greatly improves the radiation effect, thereby making higher the heating efficiency of the made heating or warming device.
Description
Technical field
The utility model relates to the radiating subassembly of a kind of electric heater, particularly a kind of electric heater.
Background technology
Electric heater is core parts of making various heating or heating system, in the electric heating device commonly used at present, the heating element heater of Cai Yonging is enforceable ventilation heating element heater at first, as the heating element that turns to heating wire, or the heating element that adopts the PTC heater element to make, then, in order to improve radiating effect, the electric heater of finned heatsink has appearred directly being provided with outside electrothermal tube, as in the patent No. being 95241936.X (notification number is CN2228626Y) Chinese utility model patent " Electric heater ", the patent No. is that the Chinese utility model patent " electric heating air heating component " and the patent No. of 96238395.3 (notification number is CN2275692Y) is in the Chinese utility model patent " multi-function electric air heater " of 98220867.7 (notification number is 2338697Y), such electric heater is all disclosed, yet because the caliber of electrothermal tube is limited, the contact-making surface that finned heatsink is in direct contact with it is also just limited, thereby influences radiating effect.
Summary of the invention
Technical problem to be solved in the utility model is the radiating subassembly that the better electric heater of a kind of radiating effect is provided at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the radiating subassembly of electric heater includes finned heatsink, it is characterized in that, described finned heatsink has a central cavity, one shape is inserted among this cavity, and the outer wall of shape and the inwall of this central cavity are close to, and described shape also has at least one can hold heating insertion central cavity wherein.
Described shape can be involuted by two root section bars, and connects one at both joint in convex tendon-groove mode; For the convenience on making, the shape of described two root section bars, size with identical be good.
Described finned heatsink can be whole, also can be spliced outside shape by a plurality of in the axial direction, at this moment, accuracy in order to guarantee to splice, also assembling is for convenience located in the convex-concave mode between the central cavity of described shape outer wall and finned heatsink in the axial direction.
Described finned heatsink can be a single piece, also can be formed by connecting by its central part and its aliform position.The aliform position of described finned heatsink can have more than two, and good evenly to be distributed as diametrically, that is, when the aliform position is four, be distributed as good to be the X type; For strengthening radiating effect, described finned heatsink can have many places punching and bending on its aliform position, to increase area of dissipation.
Compared with prior art, advantage of the present utility model is to have improved the shape of setting up an intermediate thermal conductivity between heating and the fin by being arranged on radiating effect greatly, thereby made the heating or the heating system thermal efficiency made higher.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, be embodiment one of the present utility model, the radiating subassembly of this electric heater comprises finned heatsink 1, it has two aliform positions 12, its central part 11 has a cavity, two sub-shape 2 involutory being inserted among this cavity 11, and the outer wall of interest genotype material 2 and the inwall of this central cavity 11 are close to, described two interest genotype materials 2 involutory backs also form one in central authorities and can hold heating insertion central cavity 22 wherein, and connect one in joint 21 convex tendons-groove mode; In the present embodiment, for the convenience on making, the shape of described two root shapes, size are with identical.
Assembling can be provided with axial recessed position 23 on described two interest genotype materials, 2 outer walls for convenience, and finned heatsink 1 then has corresponding axial protrusion position 15, both convex-concave location.Under this structure, described finned heatsink 1 also can be spliced by a plurality of in the axial direction.
For increasing area of dissipation, described finned heatsink 1 has many places punching 13 and bends 14 on its aliform position 12.
As shown in Figure 2, be embodiment two of the present utility model, different with embodiment one is that the aliform position 12 of its finned heatsink 1 can have four, and evenly distributes diametrically, is the X type, to strengthen radiating effect.
As shown in Figure 3, be embodiment three of the present utility model, different with embodiment two is, its two interests genotype material, 2 involutory backs form two in central authorities and can hold heating and insert wherein central cavity 22, to be fit to powerful electric heater.
