A kind of supercritical carbon dioxide working medium vehicular air cooling unit, including wind turbine 1, frame 2, plate beam 3, bobbin carriage 4, it is described
2 both sides installing plate beam 3 of frame, the plate beam 3 use base tube fin structure, and 8 side working medium of base tube is supercritical carbon dioxide, fin 9
Side working medium is air；3 both ends of plate beam are installed by bobbin carriage 4；One end of the bobbin carriage 4 opens up the adapter of carbon dioxide import and export respectively
5th, 6, set between the bobbin carriage 4 of the other end connecting tube 7 to realize the flowing of carbon dioxide working medium double-flow or multipaths；Wind turbine 1 is set
Put at the top of frame 2, so as to form the supercritical carbon dioxide working medium vehicular air cooling unit of monoblock type.
The utility model and its advantage are further illustrated below in conjunction with the accompanying drawings.
Embodiment 1, with reference to Fig. 1, a kind of hollow cool equipment of supercritical carbon dioxide working medium vehicular air cooling unit uses four
Group plate beam（Double-flow）Heat transfer process is completed, whole unit includes wind turbine 1, frame 2, plate beam 3, bobbin carriage 4, carbon dioxide inlet and outlet
Adapter 5,6 and connecting tube 7 etc..Supercritical carbon dioxide after turbine does work from the entrance sleeve 5 on plate beam tube case into
Enter, by plate beam, flowed out from the discharge connection 6 on bobbin carriage.For air under the action of wind turbine 1, ecto-entad is horizontal to skim over fin 9,
Realize that cross-current exchanges heat with the supercritical carbon dioxide in base tube 8, since supercritical carbon dioxide can be in the volume of very little
Transmit very big energy so that the air cooling unit heat exchange efficiency is high, compact-sized, it can be achieved that the requirement of vehicle-mounted transport.
The frame can use carbon steel structure, and function is to provide support for plate beam and wind turbine, using V-shaped structure, V-shaped
Frame and horizontal direction angle are between 70 °~75 °.V-shaped frame structure helps to improve the trafficability performance of air, and enhancing passes
Hot property, can further improve the heat exchange efficiency of unit.The wind turbine is induced air type wind turbine, above frame hollow position,
It is poor for increasing air external and internal pressure, carry power for air side.The air quantity of wind turbine can be in due course according to the environment temperature of Various Seasonal
Adjusting size, realizes the target for reducing fan energy consumption and operating cost.
After plate beam in this air cooling unit is connected with bobbin carriage and each adapter, frame both sides are arranged in plate beam horizontal symmetrical,
Bobbin carriage is located at left and right sides of frame.With reference to Fig. 2,3, illustrated by taking the plate beam of V-type frame side as an example, frame side there are two groups
Plate beam, the flow number of substrate tube carbon dioxide working medium are double-flow, it is necessary to set connecting tube, by connecting tube by different journeys
Two bobbin carriages carry out unicom, and carbon dioxide enters from base tube side entrance sleeve 5, enter next base tube flow by connecting tube 7, change
Flowed out after heat from discharge connection 6, another side plate Shu Tongli of frame.
The plate Shu Caiyong large scales base tube fin structure, referring to the drawings 4, base tube is porous belts tooth aluminium flat conduit, the flat tube
Completed using overall thermal extrusion forming process, which can strengthen the intensity of flat tube, while its internal hole structure phase

Come out of the stove behind region, realize transmission soldering under the protection of atmosphere in burner hearth.It is close using vacuum with traditional plate-fin air cooling apparatus
Close soldering processes to compare, the weld length of plate beam is no longer limited by soldering oven size, related with the length of whole production line, at present
The plate Shu Changdu of controlled atmosphere soldering processes soldering is up to 15 meters, it is no longer necessary to which multiple devices connection in series-parallel, structure are compacter.Together
When aluminium material, good heat conductivity, heat transfer coefficient height use due to base tube and fin.
Embodiment 2, as shown in figures 8 and 9, the implementation process of the implementation process and embodiment 1 of embodiment 2 are essentially identical.No
It is that the frame of example 2 uses character "door" form structure with part, frame and horizontal direction angle are 90 °, and plate beam is vertical, two
Positioned at plate beam, both sides, working medium enter bobbin carriage to the adapter of carbonoxide inlet and outlet straight up and down up and down.
Air cooling apparatus length, height, the arrangement of plate beam and flow number etc., can be adjusted according to specific operating mode, make
It meets the general requirement of vehicle-mounted air cooler.The plate beam arrangement of V-type frame and door shape frame may be either horizontal is alternatively
It is vertical；Meanwhile if single process operating mode, then no longer need to set connecting tube；, it is necessary to set under double-flow and multipaths operating mode
Two bobbin carriages of different journeys are carried out unicom by connecting tube by connecting tube.
During utility model works, hot fluid supercritical carbon dioxide enters bobbin carriage by inlet connection, even into base
Pipe internal flow, air pass through fin under fan action.Since the temperature difference exists, hot fluid carbon dioxide transfers heat to sky
Gas, so as to fulfill the purpose of heat exchange.Due to the special physical property of supercritical carbon dioxide, the occupation of land face of air cooling unit can be greatly reduced
