Abstract

The utility model relates to an efficiency heating package. The utility model is distinguished from the existing fishbone-shaped P T C heating package. The heat dissipating component comprises a frame and a heat sink. The heat sink is fixedly inserted into the frame. All the frames are connected by the insulating connection. The P T C heater is arranged between the frames. Because the utility model adopts the frame type dissipating component structure, the heat sink is thin. The efficiency heating package saves material and increases the unit heat dissipating area and quickens the heat dissipation and obviously raises the thermal efficiency. The efficiency heating package has simple assembling process and high productive efficiency. The utility model can be widely used for the electric heating appliance such as the air conditioner (cold and hot air), the hot-blast machine and the drier.

Description

Efficiency heating package

The utility model relates to a kind of heat generating component, belongs to the improvement of electrothermal component.

General heating wire, the Electric radiant Heating Film etc. of adopting are made heater in traditional electroheat technology, exist service life short, can not A.T.C etc. shortcoming.Adopting advanced PTC with premium properties such as power saving are durable, safe and reliable at present existing many family expenses electric heating appliances is heater, but existing is that the heat generating component of heater all is to be to support bone with the bar shape by PTC, the PTC element is installed in the bar shape, the fin arrangement is installed in bar shape and forms the herring-bone form structure outward, because the fin of this version is thicker, makes assembly exist volume big, it is many to consume material, the shortcoming that thermal diffusivity is relatively poor influences the raising of the thermal efficiency.

The utility model improves at the deficiencies in the prior art, aims to provide a kind of province material, thermal diffusivity is good, the thermal efficiency is high heat generating component.

The utility model as shown in Figure 1, form by PTC heater (3), array radiating subassembly (2), be characterized in that radiating subassembly (2) comprises framework (201) and fin (202), fin (202) is inlayed and is fixed in the framework (201), fused by the insulation attachment between each framework (201), PTC heater (3) installs between each framing (201).The utility model is owing to adopt the frame-type radiating subassembly, and fin thickness can be done thinlyyer, and the area of dissipation under the unit volume is increased, and heat radiation is accelerated, thereby realizes improving the purpose of the thermal efficiency.

Fin of the present utility model (202) thickness generally is controlled between 0.2～0.6mm.Assembly is looked the watt level requirement of product, and the group number of selected radiating subassembly (2) is inhaled the number of PTC heater (3).

The utility model is compared with old-fashioned herring-bone form structure owing to adopt framework to inlay corrugated heat radiation assembly structure, and outstanding advantage is arranged: the one, and the fin thin thickness, under identical heating power prerequisite, assembly volume reduce near half, material is saved over half, weight is corresponding also to be reduced; The 2nd, area of dissipation increases, and heat radiation is accelerated, and the thermal efficiency improves; The 3rd, the installation manufacturing process is simple, helps enhancing productivity.The utility model is widely used in electric heating appliances such as air conditioner (cold, hot two-purpose), warm-air drier, dryer, hand dryer.

Fig. 1 is the utility model structural representation.

Embodiment: this is for example shown in Figure 1, include three radiating subassemblies (2), one of them width is bigger, each assembly is bonded as one by heat-resistant adhesive, insulant be separated by (this example is a heat-resistant adhesive) is arranged between each framing, have only the PTC heater to play the conducting effect, each framework (201) all has the plug (1) that is used to connect power supply.Be provided with three PTC heaters (3) between every framing (201), be provided with the bearer bar (4) of insulation blocking effect around it.Fin (202) thickness is 0.3mm.This routine power is 1200W, its with the old-fashioned heat generating component of power relatively, volume can reduce half, consumption aluminium amount saves 280%, and airspace increases, radiating efficiency improves 28%.
