Abstract

The present disclosure provides an air conditioning device, a cooling system, and a motor vehicle. The air conditioner comprises a shell, an air door and a connecting channel, wherein the shell is provided with an air channel, the air door is arranged in the air channel and is provided with a rotating shaft, the shell is provided with the connecting channel which is communicated with the inside and the outside of the shell, and the rotating shaft of the air door is a hollow rotating shaft and is connected to the connecting channel so that the air channel is in fluid communication with the outside of the shell. The cooling air flow in the air duct can be guided into the box body outside the shell through the arrangement, so that the lower temperature in the box body can be kept even in high temperature in summer. And above-mentioned setting still can make just flowing to the cooling air current direct guide to the box of air door department, promotes cooling efficiency, avoids additionally seting up the cooling hole in other positions of casing and leads to the integrated level low, difficult processing and cooling efficiency subalternation problem. In addition, the communication channel can be selectively communicated with the hollow rotating shaft of any air door, so that the degree of freedom of operation is improved, and the problems that the cooling holes are additionally formed in the shell, so that the flexible setting cannot be realized and the like are avoided.

Description

Air conditioning device, cooling system and motor vehicle Technical Field The present disclosure relates to an air conditioning apparatus, a cooling system including the air conditioning apparatus, and a motor vehicle including the cooling system. Background The vehicle glove box is a storage box positioned in front of the copilot and used for storing sundries and the like. In general, a glove box is relatively sealed with an air conditioner in a vehicle, cold air blown out by the air conditioner cannot enter the glove box, and the arrangement of the air conditioner in the glove box can cause the excessively high temperature in summer, so that foods, beverages and articles which are easy to melt and deform cannot be stored. Accordingly, those skilled in the art have been directed to developing a new air conditioner that overcomes the above-described drawbacks of the prior art. Disclosure of utility model The present disclosure provides an air conditioner, in which a communication passage communicating with a hollow rotation shaft of a damper is provided in a housing of the air conditioner, and a cooling air flow in an air duct is guided to the outside of the air conditioner, for example, to a case outside the air conditioner, so that the case is cooled, and thus, even when the temperature is high in summer, the inside of the case can be kept at a low temperature. Furthermore, the above-mentioned setting of this disclosure still can make just flowing to the cooling air current of air door department (i.e. the cooling air current that has not passed through other heat exchanges yet) direct guide to the outside box of air conditioner in, promotes the cooling efficiency to the box, avoids additionally seting up the cooling hole in other positions of casing and leads to the problem such as integrated level low and cooling efficiency is not enough. In addition, the communication channel can be selectively and fluidly communicated with the hollow rotating shaft of any one of the two air doors, for example, the communication channels with the free ends plugged can be respectively preset in the shells corresponding to the hollow rotating shafts of the two air doors, and one communication channel can be opened at any time according to actual requirements, so that the degree of freedom of operation is improved, and a series of problems that the cooling holes are additionally formed in the shells, so that the processing is difficult, the flexible setting is impossible and the like are avoided. The disclosure provides an air conditioner comprising a housing having an air duct, an air door disposed in the air duct and having a rotation shaft, wherein the housing has a communication passage communicating an inside and an outside thereof, and the rotation shaft of the air door is a hollow rotation shaft and is connected to the communication passage so that the air duct is in fluid communication with the outside of the housing.
