Airplane air conditioner component bin

Abstract

The invention discloses an airplane air conditioner component bin. The airplane air conditioner component bin comprises an outer bin body which is provided with a cold source inlet. The airplane air conditioner component bin further comprises an inner bin body which is located inside the outer bin body and surrounds an airplane air conditioner component. An air interlayer is formed between the inner walls of the outer bin body and the outer walls of the inner bin body. At least one of the outer walls of the inner bin body is provided with vent holes. The inner bin body is provided with an exhaust opening. The airplane air conditioner component bin can carry out effective cooling on the air conditioner component.

Description

Technical field [0001] The invention relates to an aircraft, and in particular to a ventilation cooling system for an air-conditioning component cabin of a civil aircraft. Background technique [0002] Electronic equipment cooling is one of the key areas of civil aviation, and the safety requirements are very high. The application of multi-electric technology means that more and more heat is generated, and the cooling of equipment has also attracted more and more attention. Among them, non-pressurized cabins have no pressure regulation requirements, so the economic consideration of cooling is particularly important. . [0003] A typical example is an air-conditioning component. The air-conditioning component is the most important refrigeration unit of an aircraft and generates a great amount of heat. The heat absorption problem of the air-conditioning component compartment is an urgent problem for the aircraft. [0004] In this regard, aircraft in active service mainly adopt the fo...

AI Technical Summary

Problems solved by technology

[0005] Most wide-body aircraft are long-range aircraft. If the ventilation and cooling of air-conditioning components cannot be properly handled, the performance of the components themselves will not be guaranteed, and there will be great hidden dangers in structural safety.

Even narrow-body short-range aircraft such as the A320 have repeatedly experienced air-conditioning system overheating failures; the second and third processing methods must suck ram air into the onboard system, and ram air is one of the important sources of aircraft fuel compensation loss. The increase in the use of ram air is also considered to reduce the economy of the aircraft; the fourth is the same as before, the source of cold source air is generally ram air or engine low-pressure bleed air, which also increases the overall fuel compensation loss of the aircraft

In addition, all three methods require an additional cooling device, which not only increases the weight, but also is not convenient for the installation and maintenance of the air conditioning components and their cabins

[0006] The most important thing is that the relevant design generally only pays attention to the key heat-generating areas, and does not deal well with the heat accumulation effect in dead-angle areas such as cabin boundaries
