Detailed Description
An air cooling unit is arranged at the top of a refrigerator car 1 and used for refrigerating the interior of the refrigerator car 1 and keeping the refrigerating effect in the transportation process.
This air cooling unit includes unit housing 2, air intake, set up in condenser 3, the condensation fan 4 in the unit housing 2, the windward side of unit housing is equipped with the part that the hypsokinesis set up, be provided with vertical section 7 between the higher one end of the slope part of windward side 6 and the unit housing 2 top, the top of unit housing 2 is close to air outlet 8 has been seted up to section 7 one side. Along with the promotion of refrigerator car 1's functioning speed, the air moves on the 6 inclined planes of windward side and forms ascending air current, and the guide effect of terminal surface in addition can form certain regional negative pressure zone at the terminal surface rear, and because air outlet 8 sets up the one side of being close to the terminal surface, consequently when refrigerator car 1 high-speed operation, air outlet 8 still can keep normal air output, owing to be that the negative pressure can also help promoting the air output even, has ensured the normal refrigeration effect of air cooling unit.
Specifically, the windward side 6 is divided into a vertically arranged air inlet section and an obliquely arranged windward section, the air inlet is a second air inlet 9 formed in the windward section, a first air inlet 10 formed in the air inlet section, the second air inlet 9 and the first air inlet 10 are both arranged in a grid manner, and a grid opening of the second air inlet 9 is larger than a grid opening of the first air inlet 10. The air inlet section is directly fixed at the top of the refrigerator car 1, the position of a first air inlet 10 formed in the air inlet section is lower, the air inlet section is closer to the car roof, when the refrigerator car 1 is in a static state, the condensation fan 4 normally runs, and most of air inlet enters the interior of the unit shell 2 from a second air inlet 9 of the air inlet section closer to the condensation fan 4 so as to meet the requirement of condensation. When the refrigerator car 1 runs at a high speed, at the moment, main air enters from the first air inlet 10, and although the opening of the first air inlet 10 is small, the condensation requirement can be met by matching with a high air speed.
In order to increase the contact area between the intake air and the condenser 3 and protect the condenser 3, in this embodiment, the condenser 3 is disposed inside the unit housing 2, and the condenser 3 is disposed obliquely along the oblique direction of the windward side 6, that is, the condenser 3 and the windward side 6 are substantially parallel, and the condensing fan 4 is disposed behind the horizontal of the higher end of the condenser 3 and fixed on the unit housing 2, although in other embodiments, the condensing fan 4 may be disposed above the higher end of the condenser 3 and fixed on the unit housing 2.
