Abstract
The utility model belongs to the field of vehicle air conditioner manufacturing and particularly relates to an air conditioning system for a large or medium electric passenger car. The air conditioning system for the electric passenger car comprises a condenser, wherein an inlet pipe of the condenser is connected with a compressor, an outlet pipe of the condenser is connected with an inlet pipe of an evaporator, an outlet pipe of the evaporator is connected with the compressor, two or more air supplying fans are arranged on the periphery of the evaporator, the condenser is composed of two rectangular cooling coilers and condensate fans, the two cooling coilers are symmetrically distributed on a supporting plate, outer edges of the two cooling coilers are higher than the inner edges of the two cooling coilers, namely the diameters of the two cooling coilers become smaller gradually from bottom to top, and the condensate fans are horizontally arranged right above the cooling coilers. The arrangement mode of the condenser enables the structure of a unit to be more compact and the heat exchanging efficiency to be higher.
Description
Technical field
The utility model belongs to air conditioning for automobiles and manufactures field, is specifically related to a kind of big-and-middle-sized air conditioner for electric motor coach system.
Background technology
The battery capacity of pure electronic large and medium bus is limited, more responsive to the efficiency of air-conditioning, weight ratio.Existing electronic large and medium bus air-conditioning condenser adopts copper pipe aluminum fin formula heat exchanger more because copper than heat exchange efficiency great and copper pipe aluminum fin formula condenser not highly cause condenser Heavy Weight, size is large, refrigerant charge is many.And because Tong China belongs to scarce resource, price is very high, therefore air-conditioning cost improves greatly, is unfavorable for marketing.Existing electronic large and medium bus air-conditioning adopts three-phase alternating current blower fan more, and the large efficiency of blower fan weight is low, simultaneously in prior art, the condenser of air conditioner for electric motor coach is arranged on condensation fan side, the dead zone area of condensating wind circulation is large, and condensation efficiency is lower, and inhomogeneous cooling is even.
Summary of the invention
The purpose of this utility model is to provide the air conditioner for electric motor coach system that a kind of heat transfer efficiency is high, volume weight is less, production cost is low.
For achieving the above object, the utility model provides technical scheme: a kind of air conditioner for electric motor coach system, comprise condenser, the entrance pipe of condenser is connected with compressor, the export pipeline of condenser is connected with the entrance pipe of evaporimeter, the export pipeline of evaporimeter is connected with compressor, along evaporimeter periphery, there are two or more breeze fans, it is characterized in that: condenser consists of two rectangle cooling coils and condensation fan, described two cooling coils are arranged symmetrically in gripper shoe, the plate face that the outer ledge of two cooling coils is two cooling coils higher than inside edge presents gathering shape from bottom to top, described condensation fan is horizontally disposed directly over cooling coil.
Technique effect of the present utility model is: the arrangement of condenser makes the structure of unit compacter, and heat exchange efficiency is higher.
Accompanying drawing explanation
Fig. 1 is assembly structure schematic diagram of the present utility model;
Fig. 2 is condenser top view of the present utility model;
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
As Fig. 1, shown in 2, a kind of air conditioner for electric motor coach system, comprise condenser 20, the inlet duct of condenser 20 is connected with compressor 50, the outlet of condenser 20 is connected with the entrance of evaporimeter 60, the outlet of evaporimeter 60 is connected with compressor, along evaporimeter 60 periphery, there are two or more breeze fans 70, it is characterized in that: condenser 20 is by two rectangle cooling coil 20a, 20b and condensation fan 30 form, described two cooling coil 20a, 20b is arranged symmetrically in gripper shoe 10, two cooling coil 20a, the outer ledge of 20b is two cooling coil 20a higher than inside edge, the plate face of 20b presents gathering shape from bottom to top, described condensation fan 30 is horizontally disposed above cooling coil 20.This arrangement makes condenser structure compacter, and the air-flow that condensation fan 30 blows simultaneously can directly pass cooling coil 20, and this just makes condensating wind can farthest take away the heat distributing in cooling coil 20, thereby makes heat exchange efficiency higher.
As shown in Figure 3, condensation fan 30 is arranged on case 40, and the edge of case 40 is connected with the edge seal of gripper shoe 10, and the cavity between case 40 and gripper shoe 10 forms a sealing gas channel.The direction that in figure, the direction of arrow indication is air current flow, when condensation fan 30 work, air-flow is finally released to car body outside by cooling coil 20, and in whole process, air-flow is loose excessive nowhere, can only flow according to set path, the heat exchange efficiency that this also improves to a certain extent.
As shown in Figure 2, every two condensation fans 30 are one group of corresponding cooling coil 20, the top that two condensation fan 30a in each group, 30b interval are arranged in cooling coil 20a.Because cooling coil 20 lengthwise dimension are larger, therefore a condensation fan 30 cannot meet heat exchange demand, adopts two condensation fans 30 to be one group and just can allow cooling coil 20 not have individual position to have uniform air-flow to pass through, and has accelerated radiating rate.
The course of work of air conditioner for electric motor coach system is controlled by electronic control module 80, and after operating personnel assign refrigeration instruction, electronic control module 80 is automatically controlled each several part and carried out work.First, low pressure refrigerant vapor in evaporimeter 60 is inhaled in compressor 50, be compressed into high temperature and high pressure steam, through blast pipe, enter cooling coil 20, in cooling coil 20, be condensed into high temperature high pressure liquid, liquid refrigerant drying filter enters expansion valve and reduces pressure, become low-temp low-pressure liquid, then enter evaporimeter 60, the thermal air current pervaporation device 60 that now breeze fan 70 draws in compartments, cold-producing medium in evaporimeter 60 absorbs airborne heat gasification, and air themperature can reduce simultaneously, and breeze fan 70 is sent into cold air in compartment again.The cold-producing medium of gasification is again inhaled into compressor 50 and forms kind of refrigeration cycle.
