Abstract

The utility model discloses a warmer. The utility model comprises a fan and a heating facility, wherein, the heating facility is composed of a metallic finned pipe, a resistance wire and insulating and heat conducting filler; the resistance wire penetrates through the middle of the metallic finned pipe, and the insulating and heat conducting filler fully fills the space between the resistance wire and the metallic finned pipe. The utility model solves the problem of low thermal efficiency of the existing warmer; the utility model has the advantages that thermal efficiency is high, the utility model heats quickly, the temperature of discharged air is high, energy is saved, etc.

Description

Warmer

The utility model relates to a kind of warmer.

As heater, it has heater temperature height, lacks, uses the characteristics of fan forced convection heat time heating time popular in the market warmer with ptc material.But, because its heater is very thin thread ptc material, heat transfer area is very little, and according to heat transfer principle, (annotate: K is a heat transfer coefficient to Q=K*T*F, T is a heat transfer temperature difference, F is a heat transfer area), though it has higher K and T, because its F is very little, so quantity of heat given up Q is limited, the thermal efficiency is not high.

The purpose of this utility model provides the high warmer of a kind of thermal efficiency.

The purpose of this utility model is achieved in that warmer comprises fan and heater, heater is made up of metal fin pipe, resistance wire, insulating heat-conductive filler, resistance wire passes in the middle of the metal fin pipe, is full of the insulating heat-conductive filler between resistance wire and metal fin pipe.

The metal fin pipe of warmer is arranged in parallel.

The fan of warmer is positioned at a side of metal fin pipe.

Be respectively arranged with a tube sheet at the two ends of metal fin pipe, the metal fin pipe is fixed between the tube sheet.

The utility model has the advantages that: (1) thermal efficiency height.The utility model has adopted the metal fin pipe, has increased heat transfer area F widely, and heat exchange amount Q is increased considerably, and has improved the thermal efficiency of whole device.(2) heating is fast.The utility model adopts the structure of special metal fin pipe built-in resistor silk, so when increasing heat transfer area F, also guarantee to have very high T and K, so it has the advantage identical with the ptc material warmer fully: heater element surface temperature height, heat time heating time is short, the energising instant heating.(3) leaving air temp height.The utility model is provided with fan in a side of heating element heater, so that reach the effect of forced convection heat transfer, so go out the hot blast temperature height.Temperature in can very fast raising room during use.(4) energy-conservation.Thermal efficiency height of the present utility model just can increase substantially indoor temperature in the short time, therefore compares with using air-conditioning or existing P TC warmer, can save electric energy greatly.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that A of the present utility model is to structural representation.

As shown in Figure 1 and Figure 2, warmer comprises fan 1 and heater, heater is made up of metal fin pipe 2, resistance wire 3, insulating heat-conductive filler 4, and resistance wire 3 passes in the middle of metal fin pipe 2, is full of insulating heat-conductive filler 4 between resistance wire 3 and metal fin pipe 2.The insulating heat-conductive filler is selected quartz sand for use.This metal fin pipe 2 that resistance wire 3 is housed is arranged in parallel by certain position just formed an electro-heat equipment of forming by several metal fin pipes, in a side of electro-heat equipment one desk fan 1 is installed, be respectively arranged with a tube sheet 5 at the two ends of metal fin pipe 2, metal fin pipe 2 is fixed between the tube sheet 5.

After resistance wire 3 energisings, the heat energy that electric energy transforms promptly passes to metal fin pipe 2 by insulating heat-conductive filler quartz sand 4, and its temperature surface is raise rapidly.The heat energy that is transformed by electric energy in can be with electro-heat equipment when fan 1 rotates passes to the space rapidly, has also just finished by power conversion and the conveying of electric energy to hot blast.
