The volatile oil is needed to prevent the abrasion of equipment in the production and processing process of the air-conditioning heat exchanger, but the volatile oil is easy to cause formicary corrosion to the heat exchanger and cause the leakage of the heat exchanger, so the volatile oil drying and degreasing treatment is carried out on the heat exchanger after the heat exchanger is processed in the prior art.

The prior art mainly puts the heat exchanger into the specialized drying degreasing container to degrease, for example, utility model patent application with publication number CN108613504A discloses a workpiece degreasing device, which comprises an air inlet pipeline, a heating degreasing box body and a tail gas treatment device, wherein the heat exchanger is arranged in the heating degreasing box body, the air inlet pipeline is connected to the heating degreasing box body, and the tail gas treatment device is connected to the bottom of the heating degreasing box body; supplement gas is supplied to the heating oil removal box body through the gas inlet pipeline, and grease at the bottom of the heating oil removal box body is guided out and treated through the tail gas treatment device, so that volatile oil on the heat exchanger can be prevented from entering the surrounding environment, and the influence on the environment can be avoided.

On the other hand, the drying and degreasing speed in the prior art is low, and the inside of the heat exchanger cannot be quickly degreased, so that the heat exchanger is in a high-temperature environment for a long time, and the heat exchanger tube is easily subjected to high-temperature oxidation due to long-time heating and drying of the heat exchanger, so that the quality problem of the heat exchanger is caused.

On the other hand, because the degreasing device in the prior art needs to place the heat exchanger therein, the degreasing device in the prior art has a large volume and a large occupied space, and particularly for the heat exchanger for a large-scale air conditioner, the following problems exist:

1. the length, width and height of part of ultra-large air conditioner heat exchangers exceed the size limit of a common drying and degreasing container, and cannot be placed in a drying and degreasing machine for degreasing;

2. the ultra-large air conditioner heat exchanger is large in size, low in demand and low in yield, and if a drying and degreasing container with a corresponding size is specially designed or purchased, the corresponding drying and degreasing device has the advantages that (1) the occupied space is large; (2) the purchase and maintenance costs are high; (3) low utilization rate (if the method is used for producing the small heat exchanger, the heat loss is serious and the production cost is increased easily due to overlarge internal space);

3. the heat exchange tube of the ultra-large air conditioner heat exchanger is usually longer, the degreasing difficulty inside the heat exchange tube is higher, and if the drying and degreasing mode in the prior art is adopted, the heat exchange tube is more easily subjected to high-temperature oxidation;

4. the ultra-large air conditioner heat exchanger has a heavy weight (over 150kg), which causes the problem that the heat exchanger is inconvenient to carry.
