Description

Double-deck cocurrent flow type condenser

Technical field

The utility model relates to a kind of condenser, relates in particular to a kind of double-deck cocurrent flow type condenser, belongs to auto parts machinery field.

Background technology

The operation principle of condenser is that the steam with heat enters from condenser air inlet, and steam is in condenser internal flow, by the heat of steam being taken away with the air of condenser contact.Condenser area is larger, and condensation efficiency is higher, but because space in car covering is very limited, therefore to the length of condenser with widely have certain restriction, therefore,, in the situation that condenser area is constant, the operating efficiency that improves condenser is those skilled in the art's good problems to study.

Utility model content

The purpose of this utility model is to provide and a kind ofly from structure, changes the condenser to increase work efficiency.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:

Double-deck cocurrent flow type condenser, the flat tube piece that comprises some stacked settings, described flat tube piece is connected and composed by the first flat tube and second flat tube of two border seals, between described upper and lower two flat tube pieces, be provided with radiating fin, described the first flat tube two ends are communicated with respectively left header I and right header I, described right header I is fixedly connected with a drying bottle and both junctions offer some through holes, in described drying bottle, be provided with drier and little filter screen and sealing ring, described the second flat tube two ends are communicated with respectively left header II and right header II;

Described left header I is provided with the first partition near centre position, in described left header II, higher than the first partition place with lower than the first partition place, be respectively equipped with the second partition and Three-spacer, described left header I upper end is provided with air inlet, left header II lower end is provided with gas outlet, between left header I lower end and left header II upper end, is communicated with a breather pipe;

Described left header I, right header I, left header II, right header II two ends are all sealed, and on the flat tube piece of described top, are connected with side plate, under the flat tube piece of bottommost, are connected with lower side plate.

As preferably, described radiating fin is waveform.

As preferably, described right header I and drying bottle junction offer three through holes, and described the first through hole is located at top, and the second through hole, third through-hole are located at bottom.

According to the technical solution of the utility model, a compound condenser core again on original condenser core, and by a breather pipe, two condenser cores are communicated with, accelerated the area that in condenser, refrigerant contacts with air, thereby the heat of having accelerated condenser is changed rate.In addition, on three partition height, interval arranges, and has increased the flow process of refrigerant in condenser, has strengthened the heat of the interior refrigerant of condenser and extraneous air and has changed rate.
