Abstract

The utility model provides a multilayer parallel type parallel flow evaporator, and belongs to accessories of a vehicle air conditioner. The multilayer parallel type parallel flow evaporator is formed by integral paralleling welding of 2-5 parallel flow evaporator core bodies, and the distance t between two adjacent parallel flow evaporator core bodies is within the range of 1mm to 50mm; one end of a refrigerating fluid outflow tube is inserted into a refrigerating fluid outflow hole in a left flow collecting tube of each parallel flow evaporator core body to be communicated with the left flow collecting tube in a welded mode; and one end of a refrigerating fluid inflow tube is inserted into a refrigerating fluid inflow hole in the left flow collecting tube of each parallel flow evaporator core body to be communicated with the left flow collecting tube in a welded mode. According to the multilayer parallel type parallel flow evaporator, under the condition that the size and the weight of an evaporator assembly are not greatly increased, the ventilation area of an evaporator is increased in a multiplied mode, refrigerating capacity of the evaporator and an air conditioning system is effectively improved, the purposes of miniaturization, weight reduction and noise reduction are achieved, and installation is convenient.

Description

Multi-layer Parallel formula parallel-flow evaporator

Technical field

The utility model belongs to the accessory of air conditioning for automobiles, is specifically related to a kind of evaporimeter of air conditioning for automobiles.

Background technology

In the prior art, the evaporimeter of air conditioning for automobiles is single parallel-flow evaporator, if need to improve refrigerating capacity, can only reach by strengthening front face area, so just make the size of parallel-flow evaporator to increase, the volume of evaporator assembly also can correspondingly increase, and is not easy to install; Also need simultaneously to increase the blower fan volume, thereby the noise of air-conditioning system is increased.

Summary of the invention

There is defects for prior art, plan is improved the evaporimeter of existing air conditioning for automobiles, manufacture and design a kind of Multi-layer Parallel formula parallel-flow evaporator, make it significantly to reduce the evaporimeter area occupied, thereby reduce the volume and weight of evaporator assembly, be convenient to install and alleviate the noise of air-conditioning system.

The skill scheme that the Bian of the utility model institute gets is as follows.

A kind of Multi-layer Parallel formula parallel-flow evaporator, comprise the parallel flow evaporator core that is welded by flat tube, fin, left header, right header, dividing plate and end cap, be communicated with parallel flat tube between the left header of each parallel flow evaporator core and right header, the uniform fin that is welded with on flat tube, every header Two end end cap seal, being drilled with refrigerant flow on left header portals and the cold-producing medium ostium, dividing plate is contained on left header, between cold-producing medium tap hole and cold-producing medium ostium, it is characterized in that:

1), it is welded as a whole side by side by 2～5 parallel flow evaporator cores, between every two adjacent parallel flow evaporator cores apart from t in 1mm to 50mm scope;

2), an end of cold-producing medium effuser inserts in cold-producing medium tap hole on the left header of each parallel flow evaporator core, with left header welding UNICOM;

3), an end of cold-producing medium inflow pipe inserts in cold-producing medium ostium on the left header of each parallel flow evaporator core, with left header welding UNICOM.

The Multi-layer Parallel formula parallel-flow evaporator of the utility model structure, compare with existing single parallel-flow evaporator, can be in the situation that the volume and weight of evaporator assembly increases the draught area of the little evaporimeter that is multiplied, effectively improve the refrigerating capacity of evaporimeter and air-conditioning system, reach miniaturization, lightweight and alleviated the purpose of noise, and easy for installation.

Description of drawings

Fig. 1 is the perspective view of the utility model Multi-layer Parallel formula parallel-flow evaporator;

Fig. 2 is the planar structure schematic diagram of parallel flow evaporator core;

In the drawings, 1-cold-producing medium effuser, 2-cold-producing medium inflow pipe, 3-dividing plate, the left header of 4-, 5-end cap, 6-fin, 7-flat tube, the right header of 8-, a-cold-producing medium tap hole, b-cold-producing medium ostium.

Specific embodiments

Further illustrate concrete structure of the present utility model below in conjunction with accompanying drawing.

A kind of Multi-layer Parallel formula parallel-flow evaporator, comprise the parallel flow evaporator core that is welded by flat tube 7, fin 6, left header 4, right header 8, dividing plate 3 and end cap 5, be communicated with parallel flat tube 7 between the left header 4 of each parallel flow evaporator core and right header 8, the uniform fin 6 that is welded with on flat tube 7, every header Two end seals with end cap 5, be drilled with refrigerant flow portal a and cold-producing medium ostium b on left header 4, dividing plate 3 is contained on left header 4, between cold-producing medium tap hole a and cold-producing medium ostium b, it is characterized in that:

2), an end of cold-producing medium effuser 1 inserts in cold-producing medium tap hole a on the left header 4 of each parallel flow evaporator core, with left header 4 welding UNICOMs;

3), an end of cold-producing medium inflow pipe 2 inserts in cold-producing medium ostium b on the left header 4 of each parallel flow evaporator core, with left header 4 welding UNICOMs.

In Multi-layer Parallel formula parallel-flow evaporator of the present utility model, cold-producing medium flows into the left header 4 of each parallel flow evaporator core from cold-producing medium inflow pipe 2, flat tube 7 through each parallel flow evaporator core dividing plate more than 3 flows into right header 8, flow back to left header 4 from the flat tube 7 of each parallel flow evaporator core dividing plate below 3 again, flow out evaporimeter finally by cold-producing medium effuser 1.
