Abstract

The utility model provides a lower water receiving shell with maze form drainage water conservancy diversion structure, includes the big shell in a left side, the right side shell and lower water receiving shell greatly, lower water receiving shell and the big shell in a left side, right shell be assembled between/be connected between greatly, there is the water drainage tank of slope in water receiving bottom portion down, and it has the guide plate to distribute among the water drainage tank, and the water drainage tank end is equipped with the outlet. Guide plate thickness is even, length differs, and staggered arrangement, every guide plate inclination are 0o~50o. The utility model discloses ponding, cold air from the outlet effusion problem of current auto air - conditioning evaporator assembly comdenstion water have been solved to the lower water receiving shell of structure.

Description

A kind of lower accepting water shell with labyrinth form draining flow-guiding structure

Technical field

This utility model device belongs to automotive air-conditioning system, is related specifically to the lower accepting water shell on air conditioning for automobiles.

Background technology

Air conditioning for automobiles belongs to car comfort module, the demand such as the refrigeration that is mainly used in meeting in car, ventilation, humidity regulation, particularly that the demand of refrigeration is more and more higher. Air conditioning for automobiles carries out freezing and follows in bad process, and the low temperature liquid cold-producing medium in vaporizer absorbs heat in a large number, and in air, part water vapour forms the condensation globule in expansion core surface, and a large amount of globules are finally pooled to downwards vaporizer lower accepting water shell and discharge outside car. Existing automobile air-conditioning evaporator assembly condensate water discharging mechanism design imperfection, often occur condensed water be stored in evaporator shell and expansion core body, cold air from phenomenons such as discharge outlet effusions, cause impeded drainage, poor refrigerating efficiency. Hydrops remains in the corrosion that can cause vaporizer aluminum pipe in expansion core body and breaks and then cause condensing agent to leak, and causes be substantially reduced the service life of air conditioning for automobiles, occupant is uncomfortable.

Utility model content

The purpose of this utility model is in that to provide a kind of lower accepting water shell with labyrinth form draining flow-guiding structure, and the lower accepting water shell of this structure solves the hydrops of existing automobile air-conditioning evaporator assembly condensed water, cold air is overflowed problem from discharge outlet.

For achieving the above object, the technical solution of the utility model is:

A kind of lower accepting water shell with labyrinth form draining flow-guiding structure, including left big shell, right big shell and lower accepting water shell, the big shell of lower accepting water shell and a left side, right big shell assembly connection; It is characterized in that: have the rhone of inclination bottom lower accepting water shell, in rhone, distribution has deflector, and rhone end is provided with discharge outlet.

Deflector thickness uniformly, length differ, be staggered, every piece of deflector angle of inclination is 0o��50o.

Good effect of the present utility model is: this utility model by setting up the flow-guiding structure of labyrinth form inside lower accepting water shell, the condensed water that evaporator core surface is discharged can be made to arrive discharge outlet along the incline direction of each deflector successively and discharge smoothly outside car, solve the hydrops problem in lower accepting water shell housing, avoid the corrosion of vaporizer aluminum pipe and break, prevent cold-producing medium leakage etc., improve the service life of air conditioning for automobiles and the comfort level of occupant; The deflector simultaneously supporting evaporator core compresses the foam-rubber cushion of base of evaporator, it is prevented that cold air spreads, and improves refrigerating efficiency; The deflector of labyrinth form can hindering cold air to flow along water (flow) direction, overflowing from discharge outlet, thus promoting refrigeration.

Fig. 2 is lower accepting water shell mounting structure schematic diagram;

Fig. 3 is lower accepting water shell and expansion core mounting structure schematic diagram.

Detailed description of the invention

Detailed description of the invention of the present utility model is further illustrated below in conjunction with accompanying drawing 1-3.

Referring to Fig. 1-3, lower accepting water shell 3 directly assembles with the big shell 1 in a left side, right big shell 2. There is the rhone 4 of inclination the inside of lower accepting water shell 3, and on rhone 4, distribution has deflector 5, and the bottom of lower accepting water shell 3 is provided with discharge outlet 6. Deflector 5 thickness in lower accepting water shell 3 uniformly, length differ, in labyrinth form, be staggered, angle of inclination is 0o��50o, discharge outlet 6 is positioned at the extreme lower position of lower accepting water shell 3 housing.

Air conditioning for automobiles carries out freezing and follows in bad process, low temperature liquid cold-producing medium in vaporizer absorbs heat in a large number, in air, part water vapour forms the condensation globule on evaporator core 7 surface, condensed water flow to discharge outlet 6 along the incline direction of each deflector 5 along evaporator core 7 surface successively from rhone 4 and discharges smoothly, thus avoid housing internal water accumulation, the corrosion of vaporizer aluminum pipe and break, the phenomenon such as cold-producing medium leakage, improve the service life of air conditioning for automobiles and the comfort level of occupant. Further, since deflector is staggered, angle of inclination is appropriate, it is possible to prevent cold air from overflowing car from discharge outlet 6 with condensed water, thus effectively reducing vehicle interior temperature, promote refrigeration.

Deflector 5 compresses the foam-rubber cushion 8 of base of evaporator simultaneously, it is prevented that cold air spreads, and improves refrigerating efficiency.
