The beneficial effects of the utility model:
(1) the utility model is connected in the vehicle air conditioner as a single piece, does not need to tear open any parts in the motor-car, and installation and maintenance are very convenient.
(2) vertical partition plate that is provided with of the utility model and horizontal baffle (leaving the air-out road junction between the two) make that the evaporator interchange of heat is more abundant, the cold wind temperature out is lower, thereby good refrigeration effect, also are more conducive to save energy and reduce the cost.
(3) the utility model also has cold storage function except that refrigeration, drinks the convenience of cold product for the navigating mate of trudging summer provides for relieving summer heat.
(4) (large cargo transport trolley operator's compartment sleeping berth size can reach 220cm * 600cm), neither influence driver's operation and rest to the sleeping berth head of the particular location installed of the utility model behind vehicle skipper seat, can keep the natural ventilation in skylight again.
(5) the utility model structurally is provided with central water storage tank, scupper, and condensate water can be led to outside the car by pipeline, does not then have the problem of leaking, drip in the car.
Description of drawings
Accompanying drawing 1 is the structural representation of component parts in the utility model tank shell;
Accompanying drawing 2 is the utility model contour structures scheme drawing.
The specific embodiment
As shown in Figure 1, the utility model is to be provided with evaporator room 2, blower room 3, reefer 4 in tank shell 1.Evaporator room is positioned at the bottom of casing, top, the reefer that the blower room is positioned at evaporator room is positioned at the same side of evaporator room, blower room, and has dividing plate 41 and evaporator room, blower room alternate.The blowing engine of blower room mainly comprises motor 31, impeller 32, shrouding 36.Motor cabinet is connected with shrouding, tank shell roof; Blower room top, be that the both sides in shrouding and the formed air channel of tank shell roof respectively are provided with the air-out aperture, one of them air outlet 33 leads to outside the casing, and another exhaust vent 34 leads to reefer.Evaporator room communicates with the chamber of blower room, but is provided with horizontal baffle 35 at the homonymy of air outlet 33 between the two; Be provided with vertical partition plate 22 again and evaporator room be divided into high current district Q and weak current district R (pipeline of evaporator 21 passes vertical partition plate 22) in the middle of the evaporator room in horizontal baffle 35; The expansion valve 25 of evaporator is arranged in the casing, and its high-pressure pipe 23 (input end) connects the mouth of whole a/c system condenser; Low-voltage tube 24 (mouth) connects the input end of compressor; The casing shell bottom surface of evaporator room below is provided with central water storage tank 26, and this water storage tank end is connected with scupper 27, and can connect flexible pipe down and lead to outside the car body.In addition: described tank shell 1 is a latticed filter plate 11 with holes near the tank shell wall at evaporator 21 places, so that suck in the equipment casing from outside air; The top of described blower room blowing engine is provided with shrouding 36, but has out solar or lunar halo 37 on the shrouding, above left and right sides impeller 32; Described reefer is provided with push-and-pull dodge gate 42 (this dodge gate also is the component part of tank shell) towards the operator's compartment direction, dodge gate is installed in the middle part of reefer vertical surface, so that dodge gate can conveniently be taken the drink that is placed on the upper and lower position of reefer after opening; Be provided with the horizontal baffle 43 of sieve aperture in the reefer, the reefer bottom side has air gate 44.
As shown in Figure 2, the tank shell wall be 11 of latticed filter plates with holes towards body wall, and and body wall between leave the space, tank shell outer form height 430-480mm, long 500-600mm, wide 150-180mm.
This tank shell is installed on the end (after the skipper) that operator's compartment crouches and assists.
Below in conjunction with accompanying drawing, sketch working process of the present utility model:
The high-pressure inlet pipe of evaporator of the present utility model is connected on the mouth of condenser of the whole refrigeration system of vehicle, carry out interchange of heat by expansion valve through evaporator pipeline and the air that enters the evaporator room from filter plate, the air left and right sides air outlet from the blower room under the effect of blower wheel that has reduced temperature enters reefer and operator's compartment respectively, wherein, air outlet 33 can connect the outer wind channel in the car, the air outlet of outer wind channel is provided with the air channel (not shown) of regulating handle, is regulated the air quantity that enters in driving as required by the user; And the cold wind that enters reefer from exhaust vent 34 is descending by the sieve aperture of horizontal baffle from top to bottom, is discharged into outside the case to air gate 44.Refrigerant medium (R134a) in the evaporator pipeline is finished interchange of heat after expansion valve is exported by low-voltage tube, and enters in the compressor cycle operation so again and again.Because evaporator room is provided with vertical centering control dividing plate and horizontal baffle, just be separated into high current district and weak current district from the mean flow rate district of extraneous inlet air, weak current district air rate reduces, and it is more abundant to make it cold air and air heat exchange that evaporator distributes, and then the temperature of air outlet is lower.
To sum up, the utility model has reached the goal of the invention of expection.
