A closed circulation cooling device with a guide spiral plate

Abstract

The invention discloses a closed circulating cooling device with a guiding spiral plate, which relates to the technical field of mechanical equipment, and comprises a cooling device body, which is welded by an outer shell, an inner shell, and three partitions between the two An annular water cavity and an annular oil cavity are respectively formed between the three partitions; several oil inlet channels are connected with the annular oil cavity to form a dynamic interaction with the cooling liquid, and a spiral plate is welded in the annular water cavity to guide cooling liquid; the outer casing is provided with a water inlet and a water outlet to circulate the cooling liquid in the annular water chamber, and the casing is also respectively provided with a water outlet and an oil outlet. The annular water cavity provided by the present invention surrounds the outside of the oil guide barrel, so that the lubricating oil and the cooling liquid interact dynamically, increasing the contact area between the cooling liquid and the lubricating oil; the threaded plate in the annular water cavity can guide the cooling liquid Buffer function; the present invention forms a closed cavity through its own structure, which improves the airtightness of the annular water cavity.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to a closed circulation cooling device with a guiding spiral plate. Background technique [0002] The structure of the water tank in the prior art is generally divided into single-chamber or multi-slot spiral structure. The single-chamber water tank has a simple structure, but the cooling of the box is not sufficient, uneven, and the heat dissipation effect is poor; while the multi-slot spiral water tank ( See patent CN110081158A) Although the gearbox can be cooled evenly, the channel for cooling water circulation in the water box structure is open, and the water box structure is assembled inside the box body, and it needs to cooperate with other boxes through multiple sealing rings to A closed cavity is formed, and the sealing ring is easily cut during the actual assembly process so that the seal between the boxes is not tight, resulting in the mixing of oil and water ...

Problems solved by technology

[0002] The structure of the water tank in the prior art is generally divided into single-chamber or multi-slot spiral structure. The single-chamber water tank has a simple structure, but the cooling of the box is not sufficient, uneven, and the heat dissipation effect is poor; while the multi-slot spiral water tank ( See patent CN110081158A) Although the gearbox can be cooled evenly, the channel for cooling water circulation in the water box structure is open, and the water box structure is assembled inside the box body, and it needs to cooperate with other boxes through multiple sealing rings to Form a closed cavity, the sealing ring is easy to be cut during the actual assembly process, so that the seal between the boxes is not tight, resulting in the mixing of oil and water in the cavity, and eventually damaging the box

Secondly, whether it is a single-chamber or multi-groove spiral water box, due to the lack of dynamic circulation of lubricating oil, this reduces the contact area between water and oil to a certain extent, thereby reducing the cooling effect of the box.
