Abstract

A novel concurrent flow condenser of an automotive air conditioner comprises a radiating belt, a cooling pipe, a collecting pipe and a spacer plate which are connected in sequence by brazing; the space between the region where refrigerant liquid is accumulated in the cooling pipe in the condenser and the adjacent region where refrigerant is condensed into the liquid is provided with a small taper-shaped hole on the spacer plate part; the major diameter end of the taper-shaped hole faces upwards, namely, faces towards an inlet loop of the condenser; a straight hole or a plurality of holes can be arranged, and the bore diameter can be determined according to needs of draining rate; and the structures of other parts of the condenser are not changed. Through the partial improvement, a liquid membrane which has influence on heat exchange in the condenser is thinned, the condensation heat exchange area of refrigerant steam is enlarged, and the heat exchange coefficient is improved.

Description

The new parallel flow condenser of air conditioning for automobiles

Technical field

The utility model relates to vitals one condenser in the automotive air-conditioning system.

Background technology

At present, known automobile air conditioner parallel flow condenser is the corrugated tube type structure, is connected to form by solderings such as cooling tube, heat-radiation belt, header, dividing plates.Dividing plate is organized into groups cooling tube, forms many loops.But because the cooling tube horizontal positioned, the liquid after refrigerant vapour condenses in pipe accumulates in the pipe, forms thicker liquid film, and the part that accounts for heat exchange area has reduced the coefficient of heat transfer.

The utility model content

For under the constant situation of condenser existing structure and specification, after doing local change in a small amount, the thickness of liquid film that influences heat exchange in the condenser is reduced, increase the condensation heat transfer area of refrigerant vapour, improve the coefficient of heat transfer, the utility model provides a kind of easy structure, only the dividing plate in the header is done to change in a small amount, can realize above-mentioned purpose.

The technical scheme that its technical problem that solves the utility model adopts is: the interval in the interval that is condensed into liquid that the interval of the cooling tube inner accumulated refrigerant liquid in condenser is adjacent, on its clapboard parts, get tapered openings, the big end of taper hole upwards, promptly towards the inlet loop of condenser, tapered openings can be straight hole or porous, and the aperture is determined according to the needs of lifting rate.Its principle is that this place's dividing plate punching forms the short circuit between adjacent region, makes the liquid of part cold-producing medium directly enter next interval in the hole thus, has increased lifting rate thus, has reduced the thickness of liquid film in a last interval.

The beneficial effects of the utility model are can reduce the thickness of liquid film in refrigerant vapour condensation heat transfer interval, the heat transfer property of raising condenser.

The specific embodiment

In Fig. 1, be equipped with bellmouth on 2 districts of condenser and the dividing plate (2) between 3 districts, the bellmouth bigger diameter end on the dividing plate (2) is towards the inlet loop of condenser.

In the embodiment shown in Figure 2, have dividing plate (2) pricker of bellmouth on header (1).

In Fig. 5 and embodiment shown in Figure 6, what get on the dividing plate (2) is straight hole.

In Fig. 7 and embodiment shown in Figure 8, what get on the dividing plate (2) is porous.

Claims

1. new parallel flow condenser of air conditioning for automobiles, connect by heat-radiation belt, cooling tube, header, the soldering of dividing plate order, it is characterized in that: the interval in the interval that is condensed into liquid that the interval of the cooling tube inner accumulated refrigerant liquid in condenser is adjacent, on its clapboard parts, get tapered openings, the bigger diameter end of taper hole upwards, promptly towards the inlet loop of condenser, tapered openings can be straight hole or porous.
