Description

A kind of electric heater and air-conditioning

Technical field

The utility model relates to air conditioner parts field, it is specifically related to a kind of electric heater and air-conditioning.

Background technique

Nowadays air conditioner was received by more and more families because of the advantages that its is easy to operate, refrigerating/heating effect is good. A PTC (Positive Temperature would generally be arranged in the existing air-conditioning with heat-production functions on the market Coefficient, positive temperature coefficient) formula electric heating tube is on the air outlet of air conditioner indoor unit, the cross flow fan of air conditioner indoor unit Heat on electric heating tube is taken out of to form hot wind blowout.

Since electric heating tube in the prior art is generally all made of heat conducting pipe, cooling fin and heating element, wherein electric heating Element is fixedly mounted in heat conducting pipe, and cooling fin is then fixed on heat conducting pipe, since the wind of cross flow fan blowout passes through electric heating Wind can be generated after the blocking of pipe to make an uproar, to increase the noise of air conditioner entirety, therefore the wind by reducing electric heating tube make an uproar come The air conditioner for realizing low noise is a kind of feasible method, and present application is come therefrom.

Utility model content

The utility model is intended to provide a kind of electric heater and air-conditioning, to solve the above problem.

Concrete scheme is as follows:

A kind of electric heater, if including dry plate cooling fin, at least two heat conducting pipes and the electric heating being mounted in heat conducting pipe Element, every cooling fin all have mounting hole identical with heat conducting pipe quantity, and the heat conducting pipe passes through the mounting hole of cooling fin simultaneously It tilts all cooling fins on heat conducting pipe, equidistant be fixed on heat conducting pipe.

Further, the angle between the cooling fin and heat conducting pipe is 80 °~87 °.

Further, the angle between the cooling fin and heat conducting pipe is 83 °~86 °.

Further, the angle between the cooling fin and heat conducting pipe is 85 °.

Further, the cooling fin has the extension of one with the coaxial arrangement of respective mounting hole at each mounting hole It manages, the spacing between adjacent two panels cooling fin is determined by the length of extension tube.

Further, the heat conducting pipe is aluminum pipe, and cooling fin is fixed on by the heat conducting pipe in such a way that expansion is fixed On heat conducting pipe.

The utility model additionally provides a kind of air-conditioning comprising any one electric heating tube as described above.

Electric heater provided by the utility model has the advantage that provided by the utility model compared with prior art The cooling fin of electric heater is inclined to be arranged on heat conducting pipe, and the specific angle of cooling fin inclination can reduce axial-flow fan and blow Wind when on electric heater is made an uproar.

Detailed description of the invention

Fig. 1 shows the schematic diagram of electric heater.

Fig. 2 shows the schematic diagrames of cooling fin.

Specific embodiment

To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

As depicted in figs. 1 and 2, the utility model provides a kind of electric heater, if the electric heater radiates including dry plate Piece 10, at least two heat conducting pipes 20 and the heating element (not shown) being mounted in heat conducting pipe 20, electrical heating elements are The heating elements such as the prior art, such as PTC, every cooling fin 10 all have mounting hole 100 identical with heat conducting pipe quantity 20, institute Heat conducting pipe 20 is stated across the mounting hole 100 of cooling fin and tilt all cooling fins 10 on heat conducting pipe, being fixed on and lead equidistantly On heat pipe 20.

By the multiple authentication of applicant, with reference to Fig. 1, wherein the inclination angle alpha of cooling fin 10 is in the case where 3~10 ° Low wind noise can more effectively drop, therefore the angle β between the cooling fin 10 and heat conducting pipe 20 is preferably 80 °~87 °, that is, is pressed from both sides Angle α and angle β is supplementary angle each other.

Angle β between the cooling fin 10 and heat conducting pipe 20 is more preferably 83 °~86 °, is reduced under the angle The effect that wind is made an uproar is more excellent.

Angle β between the cooling fin 10 and heat conducting pipe 20 is more preferably 85 °, in the effect of angle decline low wind noise It is more excellent.

Angle β between cooling fin 10 and heat conducting pipe 20 is tested in the case where being 85 °, the cooling fin of electric heating tube It is obliquely installed and is vertically arranged compared to cooling fin and the electric heating tube of same specification compares, the electric heating tube that cooling fin is obliquely installed Low wind noise can drop under different wind speed, and reduced amplitude is 2~5 decibels.

In the present embodiment, with reference to Fig. 2, the cooling fin 10 has one and each self installation at each mounting hole 100 The extension tube 102 that hole 100 is coaxially disposed, the spacing between adjacent two panels cooling fin 10 determine by the length of extension tube 102, with Convenient for being set in cooling fin 10 is equidistant on heat conducting pipe 20.

Further, the heat conducting pipe 20 is aluminum pipe, and the heat conducting pipe 20 is in such a way that expansion is fixed by cooling fin 10 It is fixed on heat conducting pipe 20.This is that the expansion fixation is borehole enlargement by tube enlarging operation heat conducting pipe, so that The outer diameter of heat conducting pipe 20 also increases with it, so that cooling fin 10 is fixed on heat conducting pipe in such a way that expansion is fixed by heat conducting pipe 20 On 20.

The utility model further discloses a kind of air-conditioning with above-mentioned electric heater.

Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details On the utility model can be made a variety of changes, be the protection scope of the utility model.
