Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be further clearly, completely and detailedly described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0022] The water cooling mentioned in the present invention refers to the liquid cooling method, and water is a general term for liquid cooling medium; similarly, the water channel mentioned in the present invention refers to the channel through which the cooling liquid flows. Water should be understood as liquid in the present invention, rather than H in the chemic...

Abstract

The invention discloses a double-cylinder liquid cooling device, and the device comprises a base of a double-cylinder structure. The base is disposed at a position close to a heat source, and the interior of the base is provided with a water channel. Cooling liquid flows in the water channel in a circulating manner. The base is also provided with a locking structure, and the locking structure enables the flowing of the cooling liquid to be limited in the water channel, thereby preventing the leakage of the cooling liquid. According to the technical scheme of the invention, the cooling liquid flows in the water channel of the base in the circulating manner and the base is also provided with the locking structure, thereby preventing the leakage of the cooling liquid, avoiding the water leakage of a weld joint during grinding, preventing the falling of paint, avoiding a rough surface, and forming a flat surface of the base.

Description

technical field [0001] The invention relates to the field of motors, in particular to a double-tube liquid cooling device. Background technique [0002] In order to increase the power density of the motor, liquid cooling is generally used instead of air cooling, and the liquid cooling motor generally sets the cooling structure in the interlayer of the frame. Welded water-cooled machine base is widely used because of its short production cycle for the first piece, no need to invest huge mold costs and reliable structure. The structure of the usual water-cooled base machine is composed of an inner cylinder with a spiral water channel and a relatively thin outer cylinder. The inner cylinder of the base is very strong in structure and is used to arrange the installation interface of the motor. The outer cylinder of the base is usually In order to cooperate with the inner cylinder to form a closed waterway structure. Although the common welded water-cooled frame structure is wi...
