Description

Airborne oxygen generator with efficient heat dissipation

technical field

The utility model relates to an airborne oxygen generator, in particular to an airborne oxygen generator with efficient heat dissipation in the aviation field.

Background technique

Airborne oxygen generator is an oxygen product specially used in the aviation field. It is an indispensable continuous oxygen supply equipment for helicopters. Cooling and cooling the compressed air, the power source of the airborne oxygen generator, is a major issue in today's technical field. The problem is that the traditional technology cools the compressed air mainly through air cooling, liquid cooling, heat pipe cooling and other technical means.

Among them, air cooling is mainly to transfer heat to the surrounding environment through fans, heat sinks, etc. to achieve the purpose of heat dissipation; liquid cooling is to use liquid to force circulation under the drive of the pump to take away the heat of the radiator; heat pipe cooling is to fill the inside of the heat pipe Special liquid heat conduction medium, when there is a temperature difference between the two ends of the heat pipe, the liquid at the evaporating end will quickly vaporize, bringing the heat to the condensing end. After the liquid condenses and liquefies at the condensing end, it will flow back to the evaporating end through capillary action, and so on. , use the heat transfer medium to vaporize, absorb heat, liquefy and release heat to realize heat dissipation.

The traditional heat dissipation method of the above-mentioned airborne oxygen generating equipment has the following defects: the cooling device has many components, takes up a large space, and has a large mass, but the airborne equipment should try to meet the requirements of small size and light weight; The design is not reasonable enough, and it is difficult to use the exhaust gas channel to improve the heat dissipation efficiency, so the heat dissipation effect is not ideal. Therefore, the heat dissipation structure of the traditional airborne oxygen generator has been difficult to meet the requirements well.

Utility model content

The purpose of this utility model is to provide an airborne oxygen generator with efficient heat dissipation in order to solve the above problems.

The utility model realizes above-mentioned purpose through following technical scheme:

An airborne oxygen generator with high heat dissipation, including a frame and a compressor, the compressor includes a normal air inlet and a compressed air outlet, and the airborne oxygen generator also includes a heat dissipation fan and a heat dissipation bottom plate, the The heat dissipation fan is installed next to the heat sink of the compressor, and the heat dissipation bottom plate is installed under the compressor. The heat dissipation bottom plate is a metal plate and includes a normal air channel, a compressed air channel and an exhaust gas channel. The normal air channel communicates with the normal air inlet of the compressor, the air inlet of the compressed air channel communicates with the compressed air outlet of the compressor, and the air inlet of the waste gas channel communicates with the The waste gas outlet of the on-board oxygen generator is communicated and connected, and the waste gas channel is isolated from the compressed air channel by a metal sheet.

In the above structure, the heat dissipation bottom plate is made of metal with good thermal conductivity, so it has a good heat dissipation effect. The temperature of the exhaust gas channel is obviously lower than that of the compressed air channel, and the metal sheet is used to isolate the two, so the compression The air channel can be cooled by the exhaust gas channel, so that the temperature of the compressed air can be dropped rapidly, and the purpose of secondary cooling can be achieved.

Preferably, the waste gas channel is located above the compressed air channel.

Further, the heat dissipation bottom plate is an aluminum plate, the metal sheet between the waste gas passage and the compressed air passage is an aluminum sheet, and the aluminum sheet is integrally formed with the aluminum plate.

The beneficial effects of the utility model are:

The utility model arranges a heat dissipation fan next to the heat sink of the compressor, and through the high speed rotation of the heat dissipation fan, the heat generated during the operation of the compressor and the heat emitted by the heat conduction of the metal bottom plate are quickly and continuously taken away, so as to achieve the purpose of initial cooling.

The utility model increases the air flow channel length of the compressor of the airborne oxygen generator as a whole by setting the gas channel in the bottom plate, and increases the contact area between the compressed air and the bottom plate, and transfers the heat of the compressed gas to the outside through the heat conduction of the metal material. (The airflow temperature at the outlet of the compressor is above 93°C), so as to achieve the effect of cooling the compressed gas; the exhaust gas channel is above the compressed air channel, and the two channels are separated by the metal partition of the bottom plate, and the exhaust gas is eliminated during the oxygen production process. The exhaust gas is discharged to the outside of the equipment through the exhaust gas channel, and the exhaust gas is continuously "washed" on the outer wall of the compressed air channel (the temperature of the exhaust gas flow is about 35°C), and the purpose of secondary cooling of the compressed air is achieved through the heat conduction of the metal material itself ; The utility model as a whole has the advantages of good heat dissipation effect, small volume and light weight.
