Abstract

The utility model relates to a subcooling gilled condensing device of the air conditioners for cars in the technical field of a air conditioner for vehicles, which is mainly characterized in that a part of U-shaped pipes and corresponding core part are cut up and the cut U-shaped pipes are connected by pipelines with a drying reservoir while the cut core bodies form the part of a filter. The utility model changes the flowing route of the refrigerating route and facilitates the condensing and subcooling to combine with each other; the utility model improves the refrigerating output of the system, saves the refrigerant charge, which has good practicability.

Description

Air conditioning for automobiles supercooling tube chip condensing plant

Technical field

The utility model relates to the refrigeration system of car air-conditioner technical field, relates in particular to air conditioning for automobiles supercooling tube chip condensing plant.

Background technology

The most of pipe sheet type structure that adopts of existing car air-conditioner condensing plant, coldly do not separate for having cold or crossing with condenser, the U-shaped pipe that several rows of pipe type is arranged in its condenser core, every row's cold finger has an import and an outlet, and each row's U-shaped pipe import and outlet are all respectively through the pipeline parallel connection, unified U-shaped pipe outlet inserts dry reservoir, the outlet of dry reservoir inserts expansion valve again, its main deficiency of this form flowage structure is that refrigeration is not ideal enough, layout is also reasonable inadequately, and it is big to take up room.

Summary of the invention

The purpose of this utility model provides a kind of air conditioning for automobiles supercooling tube chip condensing plant that improves system's refrigerating capacity at existing no Overcold condensing plant above shortcomings.

The purpose of this utility model is achieved through the following technical solutions, a kind of air conditioning for automobiles supercooling tube chip condensing plant, comprise plurality of rows pipe type U-shaped pipe in the condenser core, condenser core, respectively arrange the unified inlet ductwork of U-shaped pipe, dry reservoir, it is characterized in that respectively arranging U-shaped pipe caudad Duan Chu and its core body part all disconnects, all be connected in series dry reservoir between two fractures of every row's U-shaped pipe by the road, each arranges the outlet of U-shaped pipe through the external expansion valve of unified export pipeline; The chiller core body portion that is partitioned into constitutes the supercooler part.

The utility model is by changing being connected of each comb chip U-shaped pipe and dry reservoir and expansion valve, the utility model refrigerant flow path is in use changed, form condensation and cold combining excessively, carried out cold to the condensator outlet refrigerant, the utility model topology layout is reasonable, the condenser of equal volume, band Overcold condenser effect obviously is better than not having Overcold condenser, improved system's refrigerating capacity, save the coolant injection amount, and reduced power consumption, and the utlity model has very strong practicality, economic benefit and social benefit are obvious.

Description of drawings

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the structural representation of the utility model when only drawing single U-shaped pipe in the core body.

In the accompanying drawing, the 1st, condenser core, the 2nd, U-shaped pipe, the 3rd, supercooler part, the 4th, dry reservoir.

The specific embodiment

The utility model is made of condenser core 1 and plurality of rows U-shaped pipe 2 and dry reservoir 4, at U-shaped pipe 2 caudad section places and corresponding core body partly disconnect, the incision position of every row's two U-shaped pipes 2 is connected in series dry reservoir 4 by the road, each arranges the outlet of U-shaped pipe 2 through the external expansion valve of unified export pipeline, and former condenser core 1 part that is partitioned into constitutes supercooler part 3.

Claims

1, a kind of air conditioning for automobiles supercooling tube chip condensing plant, comprise condenser core, plurality of rows pipe type U-shaped pipe in the condenser core, each arranges the unified inlet ductwork of U-shaped pipe, dry reservoir, it is characterized in that respectively arranging U-shaped pipe caudad Duan Chu and its core body part and all disconnect, all be connected in series dry reservoir by the road between two fractures of every row's U-shaped pipe, each arranges the outlet of U-shaped pipe through the external expansion valve of unified export pipeline.

2, air conditioning for automobiles supercooling tube chip type condenser according to claim 1 is characterized in that the chiller core body portion that is partitioned into constitutes the supercooler part.
