CN2515608Y - Frost-preventing stacked evaporator core body for air conditioner - Google Patents

Abstract

The utility model relates to a core of an evaporator in the automobile air conditioning. Aiming at solving the technical problem of the structure of the core of the evaporator, the utility model discloses an anti-frosting core of a laminated evaporator in the air conditioning, which is composed of a core of the evaporator, a fin, a cold plate, a clapboard, a bottom, a refrigerant inlet pipe and a refrigerant outlet pipe. The utility model is characterized in that clearance is arranged between the fin and the bottom in the low temperature area of the inlet pipe and the clapboard; the fin and the bottom are jointed in the high temperature area between the outlet pipe and the clapboard. The utility model has the advantages that the utility model can enable the condensed water to flow away and can make the evaporator not frost over with high heat exchanging efficiency.

Description

Anti-frosting air-conditioning laminated evaporator core body

Technical field

The utility model relates to the automobile air-conditioning evaporator core body.

Background technology

The automobile air-conditioning evaporator of extensive use is the stacked A/C evaporator of single hydroecium in the world at present, version in this evaporator core between heat sink and the fin mainly contains two kinds: a kind of is that fin is adjacent in the evaporator core bottom surface, this structure is not scurried wind, the loss of evaporimeter heat exchange amount is few, the heat exchange efficiency height.But, make the evaporator-condenser that is deposited on the bottom be difficult for flowing away the easy frosting of evaporimeter because base plate is not scurried wind.Another kind is that fin leaves the gap between the evaporimeter bottom surface, and this structural base is scurried wind, and the condensed water that is deposited on the bottom is flowed away easily, and evaporimeter is difficult for frosting, but owing to scurry wind-induced evaporimeter heat exchange amount loss, heat exchange efficiency is lower.In a word, above-mentioned two kinds of structures all exist defective.

Summary of the invention

At the weak point of above-mentioned existence, be to solve automobile air-conditioning evaporator core technology, the purpose of this utility model provides a kind of anti-frosting air-conditioning laminated evaporator core body, and its device frosting that can either avoid evaporating can improve the evaporimeter heat exchange efficiency again.

The utility model is to realize by following technical scheme, it is made up of evaporator core, fin, heat sink, dividing plate, bottom surface, refrigerant inlet pipe, refrigerant outlet pipe, its structural feature, be to be provided with the gap between low-temperature space fin between refrigerant inlet pipe and the dividing plate and bottom surface, high-temperature region fin and bottom surface between refrigerant outlet pipe and dividing plate fit.

Gap between above-mentioned refrigerant inlet pipe and end warm area fin between dividing plate and the bottom surface can be the 4-8 millimeter.

The utility model is respectively got the And that narrows with two kinds of structures of prior art and is become a structure, promptly is divided into two zones in an evaporator core, and one is the low-temperature space that leaves the gap between fin and the bottom surface, and another is the high-temperature region of not staying the gap.Thereby this evaporator core had to flow away condensed water, evaporimeter frost-free and the high advantage of heat exchange efficiency.

Description of drawings

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

Fig. 2 is a structure vertical view of the present utility model.

The specific embodiment

Below with reference to the embodiment of accompanying drawing, the utility model is described in further detail.

Among Fig. 1 and Fig. 2, evaporator core 1, heat sink 3,2 fens two zones of fin are the low-temperature space fin between refrigerant inlet pipe 6 and the dividing plate 4, leave the gap between this regional fin 2 and the bottom surface 5, the size in gap can be the 4-8 millimeter, and the present embodiment gap is 5 millimeters.This zone fin temperature is low, and condensed water is more relatively, so can flow away by the gap, the device frosting that avoids evaporating prolongs the effective time of evaporimeter.Be the high-temperature region fin between refrigerant outlet pipe 7 and the dividing plate 4, this regional fin 2 is adjacent to evaporator core bottom surface 5 and does not scurry wind, and high-temperature region fin temperature height, condensed water are less relatively, and evaporimeter is difficult for frosting, and heat exchange efficiency is higher.The utility model evidence on the B2 of Santana type sedan air conditioner, evaporimeter is difficult for frosting, and effectively cooling time is long, and the air-conditioning temperature-reducing amplitude improves 3-4 ℃ than prior art.

Claims (2)

1. anti-frosting air-conditioning laminated evaporator core body, formed by evaporator core, fin, heat sink, dividing plate, bottom surface, refrigerant inlet pipe, refrigerant outlet pipe, it is characterized in that being provided with the gap between low-temperature space fin between refrigerant inlet pipe and dividing plate and bottom surface, high-temperature region fin and bottom surface between refrigerant outlet pipe and dividing plate fit.

2. the air-conditioning laminated evaporator core body of anti-frosting according to claim 1 is characterized in that low-temperature space fin between above-mentioned refrigerant inlet pipe and dividing plate and the gap between the bottom surface, can be the 4-8 millimeter.
