Description
Technical field
The utility model belongs to the vehicular spare parts technical field, relates to a kind of heavy duty truck air conditioning HVAC system.
Background technology
This heavy duty truck air conditioning HVAC selects the placing flat of aluminum pipe aluminium flake formula evaporator water without fixing at present, and the middle vibrations noise that travels is large; New wind air intake around the evaporator, trough is shallow and be not enclosed in HVAC housing the inside, causes condensate water discharging not smooth, and the road surface condensed water that jolts easily leaks in the operator's compartment; Without Air Filter Filter Core and condensed water separation net, the operator's compartment inner circulating air is of poor quality, and condensed water is easily produced by boasting from blowing mouth; Aluminum pipe aluminium flake formula evaporator heat exchange efficiency is low, and HVAC selects fan delivery less than normal in addition, causes a/c system refrigeration performance weak effect.
So need now the heavy duty truck air conditioning HVAC of a kind of water-tight, low noise, high refrigerating capacity, high cleanliness.
Summary of the invention
The purpose of this utility model provides a kind of heavy duty truck air conditioning HVAC system, no matter when stopping or when travelling, can both satisfy water-tight, low noise, high refrigerating capacity, the air conditioning HVAC that the traveling comfort of high cleanliness requires.
The technical scheme that the utility model adopts is, the heavy duty truck air conditioning HVAC system, comprise that two parts form, wherein first comprises front set casing, front set casing is inner with bolt connecting fan adapter plate, the hot well that hydroecium surface, two ends is provided with sponge is connected with the blower fan adapter plate, and evaporation fan is bolted on the blower fan adapter plate; Second portion comprises set casing under the evaporator, and set casing is by screw and the assembling of rear set casing under the evaporator; Evaporator temperature sensor inserts the evaporator that collecting pipe pastes sponge, evaporator is assemblied in the assembly housing of set casing and rear set casing under the evaporator, be connected with set casing, rear set casing, evaporator temperature sensor, evaporator under the evaporator respectively with set casing on the evaporator of dash net, expansion valve turnover aluminum pipe, expansion valve are connected with the evaporator of parallel flow successively; Drain hose is inserted on the discharge port of set casing under the evaporator, and rear set casing is connected with front set casing, and element kit is arranged in the buckle that the ventilation inlet of set casing outside goes out.
The beneficial effects of the utility model are, inner each parts connect reliable, and noise is low; Adopt the high parallel-flow evaporator of heat exchange efficiency to cooperate H type expansion valve, the Wind Volume evaporation fan is to obtain high refrigerating capacity; And design trough and filter core and dash net etc. improve comfort level and air cleanliness in the operator's compartment.Thereby it is large to have solved the existing air conditioning HVAC noise of heavy duty truck, and refrigerating capacity is low, operator's compartment water inlet and the poor problem of air quality.
Description of drawings
Fig. 1 is the structural representation of the utility model heavy duty truck air conditioning HVAC system.
Fig. 2 is the structural representation of evaporator assembling mode in the utility model.
Among the figure, 1. front set casing, 2. blower fan adapter plate, 3. hot well, 4. evaporation fan, 5. expansion valve turnover aluminum pipe, 6. expansion valve, 7. element kit, 8. evaporator is 9. with set casing on the evaporator of dash net, 10. set casing under the evaporator, 11. drain hose, 12. rear set casings, 13. evaporator temperature sensors.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model heavy duty truck air conditioning HVAC system, as shown in Figure 1 and Figure 2, comprise two parts, first comprises: front set casing 1, the front set casing 1 inner bolt connecting fan adapter plate 2 of using, the hot well 3 that hydroecium surface, two ends is provided with sponge is connected with blower fan adapter plate 2, and evaporation fan 4 is bolted on the blower fan adapter plate 2; As shown in Figure 2, second portion comprises: set casing 10 under the evaporator, and set casing 10 is by screw and 12 assemblings of rear set casing under the evaporator; After evaporator temperature sensor 13 inserts the evaporator 8 frosting controlling points of collecting pipe subsides sponge, be assemblied in the assembly housing of set casing under the evaporator 10 and rear set casing 12, to be connected with set casing 10, rear set casing 12, evaporator temperature sensor 13, evaporator 8 under the evaporator respectively with the 9 usefulness screws of set casing on the evaporator of dash net, expansion valve turnover aluminum pipe 5, expansion valve 6 are connected with the evaporator 8 of parallel flow successively again; Drain hose 11 is inserted on the discharge port of set casing 10 under the evaporator.
After the rear set casing 12 of second portion pushed the front set casing 1 of first, after with screw two parts being coupled together, in the buckle that the ventilation inlet that element kit 7 is inserted set casings 12 outsides goes out.
In the utility model after fresh air filters by element kit 7, through evaporator 8 coolings, when temperature reaches certain setting value, evaporator temperature sensor 13 feedback electric signal control compressor energisings, with set casing 9 on the evaporator of dash net the condensed water that produces is filtered, be collected in the trough of set casing 10 under the evaporator and discharge operator'ies compartment by drain hose 11.Air is blown over hot well 3 heating through evaporation fan 4, from the top air outlet out, enters the air channel.
