the evaporimeter of indoor unit of floor type air conditioner mainly adopts finned tube evaporator, some hydrophilic aluminium foil fins are stacked arrangement, proper alignment has a plurality of fins holes on fin, many U-shaped copper pipes insert in the fin hole in order, end at the U-shaped copper pipe connects with return bend, form one or more refrigerants loops, the room air that flows into high temperature refrigerant in evaporimeter or the low temperature refrigerant fin by the high heat transfer system and the evaporator surface of flowing through carries out heat exchange, air is heated up or lower the temperature, and be blown into indoor under the effect of centrifugal blower from air outlet, environment temperature in conditioning chamber.
The evaporimeter of indoor unit of floor type air conditioner is all to adopt straight-plate-type version at present, in the situation that the air-conditioning products internal structural space is limited, the heat exchange area of straight-plate-type evaporimeter is also certain, be beneficial to air circulation although be provided with the air outlet of multiple directions, but evaporimeter and the room air heat exchange amount within the unit interval is restricted, and heat exchange efficiency is lower.
The utility model content
The utility model main purpose is to address the above problem and is not enough, and a kind of floor air conditioner indoor machine evaporimeter that can effectively improve the indoor machine evaporation heat exchange efficiency is provided.
Another purpose of the present utility model is to provide a kind of floor air conditioner indoor machine that can effectively improve the indoor machine evaporation heat exchange efficiency.
For achieving the above object, the technical solution of the utility model is:
A kind of floor air conditioner indoor machine evaporimeter comprises some fins that are stacked arrangement, inserts the U-shaped pipe of described fin and connects the return bend of adjacent described U-shaped pipe, the whole curved structure in the windward side of described evaporimeter.
Further, the windward side integral body of described evaporimeter is circular arc.
Further, described evaporimeter is circular arc to the direction bending of front panel of indoor unit.
Further, described evaporimeter is circular arc to the direction bending that deviates from front panel of indoor unit.
Further, the two ends line of described evaporimeter circular arc and wherein the angle between the tangent line of the circular arc of an end be 5-30 °.
Further, described evaporimeter is crooked along the bearing of trend of described U-shaped pipe.
Another technical scheme of the present invention is:
A kind of floor air conditioner indoor machine, comprise housing, indoor fan and air channel are set below described enclosure interior, air inlet and air outlet are set on described housing, further, be provided with indoor unit of floor type air conditioner evaporimeter as above above described enclosure interior.
Content to sum up, floor air conditioner indoor machine evaporimeter described in the utility model and floor air conditioner indoor machine, because evaporimeter has adopted arcuate structure, make in the situation that indoor set appearance and size is constant, increased the heat exchange area of evaporimeter, improved the heat exchange efficiency of evaporimeter, the complete machine efficiency also obviously improves.This floor air conditioner indoor machine not only efficiency grade of product increases, and in the product of ad eundem, cost descends to some extent, makes product competitiveness obviously strengthen.
Description of drawings
Fig. 1 is the structural representation of the utility model floor air conditioner indoor machine embodiment;
Fig. 2 is the structural representation of the utility model evaporimeter embodiment;
As depicted in figs. 1 and 2, housing 1, indoor fan 2, air channel 3, evaporimeter 4, fin 5, U-shaped pipe 6, return bend 7.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in Figure 1, floor air conditioner indoor machine described in the utility model, comprise housing 1, below housing 1 inside, indoor fan 2 and air channel 3 are set, be obliquely installed evaporimeter 4 above housing 1 inside, be provided with a plurality of air inlets and air outlet on the front panel (not shown) in housing 1 front.Room air enters the inside of housing 1 from air inlet, under the effect of indoor fan 2, and the evaporimeter 4 of the top of flowing through, carry out heat exchange with the refrigerant in evaporimeter 4, the air after heat exchange blows out through air outlet, enters indoor, realize indoor air circulation, the adjusting indoor environment temperature and humidity.
As shown in Figure 2, evaporimeter 4 adopts finned tube evaporator, formed by fin 5, U-shaped pipe 6 and return bend 7, the hydrophilic aluminium foil fin 5 of some straight plate shapes is stacked arrangement, and proper alignment has a plurality of fins holes on fin 5, and many U-shaped pipes 6 insert in the fin hole in order, between many U-shaped pipes 6, along continuous straight runs is arranged in parallel, mutually vertical between fin 5 and U-shaped pipe 6, the end of adjacent U-shaped pipe 6 is with return bend 7 connections, forms one or more refrigerants loops.
