A general-purpose cooling enclosure

Abstract

The invention discloses a general-purpose cooling casing, which comprises a cylindrical shell and inserts uniformly distributed on the annular outer wall of the shell in the circumferential direction. Both ends are connected with joints, and the number of water holes is an integer multiple of 2. The joints on one side are connected in pairs by stainless steel bellows, and the joints on the other side are connected in pairs by stainless steel bellows, and at least one set of joints is not connected. Stainless steel bellows, the stainless steel bellows on both sides are staggered. The invention has the advantages of simple manufacturing process, simple and convenient assembly and disassembly, high strength, no rust in the waterway, strong versatility and good cooling effect.

Description

technical field [0001] The invention relates to the technical field of motor casings, in particular to a general-purpose cooling casing. Background technique [0002] There are generally three cooling methods for motors: natural cooling, air cooling and water cooling. The structures of natural cooling and air cooling are similar, and the two can be interchanged with each other. The outer circumference of the case is evenly distributed with heat dissipation ribs. The difference is that air cooling adds a fan at the rear end of the motor to enhance the cooling effect. Water cooling is the best cooling effect among the three methods. The structure is relatively complicated and the cost is high. There are many kinds of water-cooling structures in the prior art, such as spiral grooves on the outer periphery of the casing, but its structure is far from natural cooling and air-cooling structures, and its versatility is poor. It is convenient to switch between natural cooling and a...

Problems solved by technology

The structure of natural cooling and air cooling is similar and the two can be interchanged with each other. The outer circumference of the casing is evenly distributed with heat dissipation ribs. The difference is that air cooling adds a fan at the rear end of the motor to enhance the cooling effect. Water cooling is the best cooling effect among the three methods. The structure is relatively complicated and the cost is high. There are many kinds of water-cooling structures in the prior art, such as spiral grooves on the outer periphery of the casing, but its structure is far from natural cooling and air-cooling structures, and its versatility is poor. Easy conversion between natural cooling and air cooling

[0003] In addition, there are several problems in the existing water-cooling casing structure as follows: First, if the water-cooling casing is made of steel, the strength is high, but the inside of the waterway will rust, and it will be easily blocked after a long time, resulting in poor cooling effect. If the casing is made of aluminum , although the problem of waterway rusting has been solved, the strength of the casing is greatly reduced, which cannot meet the needs of high-power motors; second, the existing water-cooling structure has complicated manufacturing processes and high costs; third, the waterway of the existing water-cooling structure is being processed It has been determined at the time of manufacture (usually one water inlet and one water outlet form a waterway), and the parallel number of waterways cannot be changed
