[0002] The transmission equipment (motor) of the common rotary oven is usually arranged at the upper part of the oven, but there is no cooling means for the transmission equipment. When the temperature in the oven continues to rise, it will affect the transmission equipment, thereby reducing the service life of the equipment. Therefore, it is necessary to implement cooling means for the transmission equipment of the rotary oven. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a natural cooling device for a rotary oven, thereby realizing a natural cooling method for the transmission equipment by combining natural convection and separate heat pipes.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A natural cooling device for a rotary oven, comprising a ventilation duct, wherein the ventilation duct has a specific structure as follows: comprising an air inlet disc, an exhaust chimney is vertically mounted on the top surface of the air inlet disc, air inlets are arranged around the air inlet disc, the top of the air inlet disc is an inclined surface, the bottom of the air inlet disc is a horizontal surface, a first circular hole and a second circular hole are respectively opened at the middle position of the top and bottom of the air inlet disc, a spring buckle is mounted at the first circular hole, the second circular hole is used for passing a motor drive shaft, the bottom and top peripheral surfaces of the air inlet disc are both provided with flange bases, namely a first flange base and a second flange base, the first flange base is used for connecting to the rotary oven, and the second flange base is used for connecting to the shell;

[0006] The outer shell covers the top of the air inlet disc, and a split heat pipe is installed inside the outer shell.

[0007] As a further improvement of the above technical solution:

[0008] The exhaust chimney is located on the higher side of the top of the air inlet disc.

[0009] The outer shell is an integrated structure with an open bottom.

[0010] A third circular hole is reserved on the top of the shell, and the third circular hole is used for passing the exhaust chimney. A third flange base is provided on the bottom of the shell for connecting the ventilation duct.

[0011] The split heat pipe comprises a condensing plate, an evaporating plate, a steam pipe and a liquid pipe. The condensing plate is an inclined hollow circular plate. The higher end of the condensing plate has a fourth circular hole for passing through an exhaust chimney. The evaporating plate is an inclined hollow circular plate. The center of the evaporating plate has a sixth circular hole for connecting the spring buckle. The higher end of the evaporating plate has a fifth circular hole for passing through an exhaust chimney. The evaporating plate is adjacent to the air inlet disc.

[0012] The steam pipe is a hollow circular tube, located at the highest point of the evaporation plate and the condensation plate, close to the exhaust chimney;

[0015] The beneficial effects of the utility model are as follows:

[0016] The utility model has a compact and reasonable structure and is easy to operate. Outdoor air enters through the ventilation disc of the ventilation duct, initially lowers the temperature of the transmission equipment, and then is discharged from the exhaust chimney. In the process, the chimney effect of the ventilation duct is fully utilized to strengthen natural convection heat exchange. Furthermore, the liquid in the evaporative cold plate in the split heat pipe evaporates due to the absorption of heat from the surrounding environment of the transmission equipment, and the steam rises to the condensation plate through the steam pipe, naturally condenses, and then flows back to the evaporation plate through the fluid pipe, forming a cycle, further lowering the temperature of the transmission equipment.

[0017] At the same time, the utility model also has the following advantages:

[0018] 1. The chimney-shaped ventilation duct structure can enhance natural convection and effectively reduce the temperature of the transmission equipment;

[0019] 2. The cooling device adopts the form of spring buckle to cope with transmission equipment of different sizes;

[0020] 3. The combination of natural convection and separate heat pipes can achieve the effect of passive cooling of transmission equipment without any power;

[0021] 4. The evaporation plate in the split heat pipe is close to the ventilation duct, which can accelerate the evaporation of the liquid and thus speed up the cooling of the equipment;

[0022] 5. The steam pipe in the split heat pipe is close to the exhaust chimney, which can accelerate the flow of steam and thus enhance the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS
