Description

A kind of compact automotive air-conditioning condenser

Technical field

The utility model belongs to the auto parts and components field, relates to a kind of automobile air conditioner parallel flow formula condenser with condenser-liquid reservoir function that is used for vehicles such as minibus, minibus.

Background technology

In the prior art, the core component of automotive air-conditioning system is refrigeration compressor, condenser, heating power expansion valve, evaporimeter, also has liquid reservoir between condenser and heating power expansion valve, and they are linked to be automotive air-conditioning system by pipeline.

Export to condenser from refrigeration compressor, belong between the higher-pressure region of cold-producing medium operation in the automotive air-conditioning system to heating power expansion valve through liquid reservoir again.The function of condenser is with the heat radiation of condensing of the gaseous refrigerant from the high temperature of refrigeration compressor, high pressure, realizes gas---liquid phase becomes, and becomes liquid cold-producing medium, and the function of liquid reservoir is the storage liquid refrigerant and removes impurity in the cold-producing medium.

Heating power expansion valve and evaporimeter are formed an evaporation tank in the automotive air-conditioning system, fixedly become a modularization integral body.But air-conditioning system for numerous vehicles, close condenser and the liquid reservoir with association of function is two parts independently, this makes troubles not only for all many-sides such as production, use, logistics, maintenance, auto parts and components quantity is increased, production cost improves, and influences the performance of enterprises.The existence of liquid reservoir causes the air-conditioning system refrigerant charge to increase, be not only the cost problem and also have environmental issue, even green refrigerant R134a also is to produce greenhouse effects, and the air-conditioning system of vehicles such as minibus, minibus is because the cold-producing medium consumption is many, and problem is more outstanding.

For can't substituting serpentine condenser, the parallel flow type condenser that solves existing structure satisfies of the instructions for use of vehicle air-conditioning systems such as minibus, minibus to condenser, the author's design has also been applied for Chinese patent ZL 2,005 200 02066.0, this employing is arranged more, the condenser of the porous flat pipe structure of multiple row not only satisfies the requirement of above-mentioned vehicle air-conditioning system to the condenser refrigerating capacity, also be condenser, liquid reservoir modularization, becoming a kind of compact automotive air-conditioning condenser provides precondition.

Summary of the invention

The technical problem that solves:

Utilize the condenser of porous flat pipe structure of many rows, the multiple row of Chinese patent ZL 2,005 200 02066.0 to make the platform of product structure, the connecting line of the refrigerant conveying between cancellation condenser and liquid reservoir, when changing liquid reservoir product structure form, change its profile, make it to be fitted together with the right header of condenser.The deficiency that this has just overcome vehicle air-conditioning system technology such as existing minibus, minibus makes at present that still two parts---condenser and liquid reservoir combine independently, has constituted a condenser module.

The technical scheme that adopts:

A kind of compact automotive air-conditioning condenser, has left header 1, its upper punch is shaped on cold-producing medium air inlet pipe interface 18, drain pipe interface 19, its inside is equipped with partition 5 regularly, has right header 2, its inside is equipped with partition 5 regularly, external mounting cylinder 8, and cylinder 8 one ends are equipped with closure plate 9, the other end is equipped with dismountable sprue 10, cold-producing medium screen pack 11 is equipped with in inside, and the porous flat pipe 3 that many row's multiple rows are housed between 13, two headers of jam is housed at the two ends of left header 1, right header 2, have the wave heat-radiation belt 4 of air regulator, side plate 12.

Beneficial effect:

Adopt the compound mode of the porous flat pipe 3 of many row's multiple rows, increased the effective length of porous flat pipe, be the effective flow process that has increased cold-producing medium, many rows' form can increase the heat exchange area of condenser, and technique scheme is useful to the refrigerating capacity that improves condenser.Adopt the scheme of right header 2 and cylinder 8 combination solderings, can cancel the air conditioning for automobiles liquid reservoir, be and reduce auto parts and components quantity, this for save material, remarkable result has reduced cost.This compact product structure, for the standardization of product, normalization, modularization have positive effect.Owing to alleviated product weight, be useful for energy-saving and environmental protection and sustainable development, cancel the useful space that liquid reservoir has been saved automobile again simultaneously.
