Description

Compact type vehicle-mounted top-mounted air conditioner

Technical field

The utility model relates to air-conditioning technical field, and in particular to one kind is applied to compact type vehicle-mounted top-mounted air conditioner.

Background technology

Now except other closed cars of automobile all do not have air-conditioning, such as closed tricycle, closed type electric a lot Car, electro-tricycle；During the broiling summer, the temperature in compartment is higher, in order to reduce the temperature in compartment, in closing tricycle Top offer skylight, traveling when, air-flow pours into in-car by skylight, play a part of cool and take a breath, still The effect to be cooled when heat using natural airflow is not highly desirable, the south particularly in warm, is not had even more Effective, especially when vehicle stops, air is in the state of geo-stationary with vehicle, and air-flow will not be poured into by skylight In-car, in-car hot gas can not exclude, and when entering to start vehicle suddenly when static after, more reach the insufferable temperature of people Degree, and skylight can not also play a part of cooling.

The content of the invention

In view of technical problem present in prior art, the utility model provides a kind of empty suitable for compact type vehicle-mounted overhead Adjust.

To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：

Compact type vehicle-mounted top-mounted air conditioner, including Overcold condenser, fan, air blower, compressor, evaporator and expansion Valve, it is characterised in that：Also include air-conditioning fixed panel and casing for air conditioner shell, the casing for air conditioner cap is on air-conditioning fixed panel Cavity is formed, diaphragm cavity is partitioned into front chamber and rear chamber, and the Overcold condenser is arranged on the right side of rear chamber, institute State the left side that compressor is arranged on Overcold condenser in rear chamber, the outlet of the compressor and the import of Overcold condenser Between connected by high-pressure gaseous pipe, the fan is placed in the top of Overcold condenser, and fan is provided with casing for air conditioner shell The window of ventilation；The air blower is placed in the right side of front chamber, and the evaporator is placed in the left side of front chamber, the air blower and Windshield cover is stamped above evaporator；The expansion valve be connected to evaporator and Overcold condenser, evaporator and compressor it Between, connected between the import of the evaporator and the lower outlet of expansion valve using low-pressure liquid pipe, the lower inlet of the expansion valve Be connected between the outlet of Overcold condenser using high-pressure liquid pipe, the outlet of the evaporator and the upper inlet of expansion valve it Between using short low-pressure gaseous pipe connect, be by long low-pressure gaseous Guan Lian between the import of the upper outlet and compressor of the expansion valve Connect；The bottom surface of the air-conditioning fixed panel is provided with and is respectively placed in evaporator, the air inlet and air outlet of air blower bottom surface, described Air-conditioning fixed panel is fixed on roof using tightening member is detachable.

The compact type vehicle-mounted air-conditioning of design makes driving more comfortable, is avoided that in-car high temperature during the broiling summer, avoids causing The situation of occupant's heatstroke；The air-conditioning is all refrigeration system inner refrigerant after air-conditioning is powered as the principle of common air-conditioning Low-pressure steam by compressor suction and boil down to high temperature and high pressure steam heel row radiated into Overcold condenser, while fan inhale The flow of outside air entered takes away refrigerant liberated heat through Overcold condenser, makes the high-temperature high-pressure refrigerant steam condensation be Highly pressurised liquid；Highly pressurised liquid enters evaporator, and the evaporation endothermic under corresponding low pressure by high-pressure liquid pipe, draws surrounding Heat, while in-car air carries out heat exchange from air inlet between the fin of evaporator, the air to turn cold after heat release is by rousing Blower fan is sent to in-car from air outlet, and such in-car air constantly circulates, and reaches the purpose for reducing temperature.High-pressure gaseous pipe, Low-pressure liquid pipe, high-pressure liquid pipe, high-pressure liquid Guan Juncong front chamber and the right side of rear chamber connect arrangement, and middle dividing plate is opened There is a breach for pipe by an adjustable flexible pipe of section being provided among long low-pressure gaseous pipe, because the height of compressor is higher than The position of evaporator and expansion valve, along with middle right clapboard, it can prevent long low-pressure gaseous pipe from wearing using adjustable flexible pipe；The sky The all parts close-coupled arrangement of tune, suitable for compact vehicle, it is not take up unnecessary space, the air-conditioning of integrated form, shortening each Circulation distance between pipe, more improves cooling effectiveness.

Further limit, left header and right header of the Overcold condenser including the left and right sides, be arranged on a left side Header and flat tube array, the fluid reservoir mounted in right header side being made up of among right header parallel flat tube, Yi Jifen Cloth is on the left of left header, four condenser brackets on the right side of right header, and it is cold that four support Overcolds are provided with rear chamber The pillar of condenser, Overcold condenser is suspended vacantly on air-conditioning fixed panel；The fluid reservoir carries out three with right header Lead to and connect, the inlet and outlet of the Overcold condenser is arranged on left header.
