Embodiment Construction

[0018] figure 1 The cooling water jacket 1 according to the embodiment of the present invention is shown, and the cooling water jacket 1 is composed of figure 2 Shown sleeve piece 2 and image 3 The shown fixing member 3 is assembled in two parts.

[0019] Such as figure 2 As shown, the sleeve member 2 is cylindrical, which is prepared from a metal pipe blank through a turning process. Pipes similar in size and thickness to the final product can be used to process the casing part 2. During the turning process, according to assembly or functional requirements, one or more ring grooves and bosses can be formed on the outer peripheral side of the sleeve member 2 by turning. The outer peripheral side of the sleeve member 2 may cooperate with the housing of the cooling device to form a channel for guiding the cooling liquid. Such as Figure 4 As shown, a boss 5 is formed on the outer side of one end of the sleeve member 2 through a turning process, and the sleeve member 2 narrows r...

Abstract

The invention relates to a cooling water jacket for a cooling device, the cooling device and a method for manufacturing the cooling water jacket. The cooling water jacket comprises a sleeve part and afixing part used for fixing the cooling water jacket on a shell of the cooling device; the fixing part is connected to the outer peripheral side of the end part of the sleeve part in a sleeved mode;at least one groove is formed in the inner peripheral side of the fixing part; a boss with a narrowed outer diameter is arranged on the outer peripheral side of the end part; and the fixing part is arranged on the boss in a sleeving mode and abuts against the end plane of the boss, wherein a stop part is arranged on the edge of the boss, so that the fixing part is clamped tightly by the stop partand the end plane; and a bump embedded into the groove is arranged in the position, corresponding to the groove, of the boss. According to the cooling water jacket, material waste in machining is reduced, the processing cost is lowered, the production period is short, and relatively high flexibility is achieved.

Description

Technical field [0001] The invention relates to the field of cooling devices. Specifically, the present invention relates to a cooling water jacket for a cooling device, a cooling device for a motor, and a method for manufacturing a cooling water jacket for a cooling device. Background technique [0002] The cooling water jacket for the motor usually has a tubular sleeve body, and a lug structure protruding outward is provided on the outside of one end of the sleeve body. In the prior art, the sleeve body and the lug structure of the cooling water jacket are generally integrally formed from raw materials through a mechanical processing technology, and there are two common processing methods. One way is to use a thick round tube as the raw material. First, use a hot bending process to heat one end of the raw tube to form a flange perpendicular to the tube wall, and then process the flange into a lug using heat treatment and machining processes. Due to the complexity of the proce...
