Description
[technical field]
The utility model relates to field of air conditioning, particularly solves the device of the local frosting of evaporimeter.
[background technology]
Air-conditioning system is the system of extensive use in the present society, and air-conditioning system generally includes devices such as compressor, condenser, evaporimeter and expansion valve, and wherein evaporimeter is to utilize refrigerant to absorb a kind of device that heat carries out heat exchange.For example the evaporimeter process that can utilize liquid refrigerants to become gaseous coolant is drawn the heat in the user room.
Existing evaporimeter adopts the finned evaporator of refrigerant pipe box aluminium foil more, please refer to Fig. 1, and it shows the structural representation of a kind of finned evaporator 100 of the prior art.Described finned evaporator 100 comprises several refrigerant pipe 102 and several fins 104.Described refrigerant pipe 102 is generally copper pipe or aluminum pipe, is usually to be horizontally disposed with; Described fin 104 is generally aluminium foil, is vertical setting usually.Liquid refrigerants flows through in described refrigerant pipe 102, and is converted into gaseous state after finishing heat exchange by described fin 104 and ambient air, flows out to follow-up other devices through described refrigerant pipe 102 again.In order to obtain heat exchange effect preferably, described finned evaporator 100 is provided with two combs, four combs even six combs or the like usually.And described finned evaporator 100 also adopts the inclination modes of emplacement, perhaps usually two finned evaporators 100 are combined into the V font and arrange the mode of placing, can be with reference to shown in Figure 2, among Fig. 2 two finned evaporators 100 are combined into the V font and arrange placement, and be provided with blower fan 200 on the top of V font, can obtain heat exchange effect preferably like this.
