Description

Technical Field

[0001] This utility model relates to the field of motors, specifically a water-cooled housing with selectable water inlet and outlet directions. Background Technology

[0002] Industrial motor water-cooled housings typically utilize cast aluminum or welded steel plate structures, with inlet and outlet directions customized to fit the customer's equipment layout. A single housing cannot meet the diverse inlet and outlet directions and locations required by different customers, necessitating redesigns for different installation scenarios. Furthermore, subsequent changes to the equipment layout necessitate the addition of complex inlet and outlet piping. Once the inlet and outlet directions of the customized housing are determined, they cannot be adjusted. Changing the direction requires cutting and welding external piping or replacing the motor, increasing the number of sealing points, raising the risk of leakage, and incurring high modification costs. When the motor installation direction changes (e.g., horizontal / vertical switching) or maintenance space is limited, existing solutions require motor replacement or the addition of complex piping, increasing flow resistance, leakage risk, and modification costs. The growing demand for cooling high-power motors necessitates improved water circuit flexibility. Summary of the Invention

[0003] The purpose of this utility model is to provide a water-cooled housing with selectable water inlet and outlet directions. By integrating multi-directional water channels into the housing body, the water inlet and outlet directions can be freely selected on-site, eliminating the cost of customized modification and the risk of seal failure.

[0004] The technical solution adopted by this utility model is as follows: a water-cooled housing with selectable water inlet and outlet directions, including a rear flange, an outer water jacket, an inner water jacket and screw seats; the outer water jacket and the inner water jacket are assembled with an interference fit, and the cavity of the two forms an S-shaped water channel; the rear flange is welded to the bottom end of the outer water jacket and inner water jacket assembly; four screw seats are opened on the outer water jacket and set at the top of the outer water jacket.

[0005] Furthermore, the outer water jacket has four screw seats with threads drilled on them. Depending on the user's actual needs, flanges or water pipes can be matched to serve as different water inlet and outlet interfaces; two are used as water inlet and outlet interfaces, and the other two are plugged with appropriate plugs.

[0006] Furthermore, the inner water jacket includes an inner water jacket cylinder, a first water-blocking ring, a second water-blocking ring, several water-blocking strips of different lengths, and a front flange; the first water-blocking ring, the second water-blocking ring, and several water-blocking strips of different lengths are arranged on the outside of the inner water jacket cylinder, and part of the inner water jacket cylinder surrounded by the water-blocking strips and the front flange is cut off to serve as an outlet window.

[0007] Furthermore, the first water-blocking ring, the second water-blocking ring, and several water-blocking strips of different lengths are specifically connected as follows: the several water-blocking strips of different lengths are divided into the first water-blocking strip and the second water-blocking strip; a first water-blocking ring is provided on the inner water jacket near the rear flange end, and a second water-blocking ring is provided on the inner water jacket near the front flange end. The length of the first water-blocking strip is shorter than the distance between the first water-blocking ring and the second water-blocking ring. The number of first water-blocking strips is odd. They are evenly distributed and staggered with the second water-blocking strips and welded to the outer surface of the inner water jacket. The first water-blocking strip and the second water-blocking ring are connected, and the second water-blocking strip and the first water-blocking ring are connected.

[0008] Furthermore, some of the water-blocking strips and the inner water sleeve body surrounding the front flange are cut off. Specifically, several water-blocking strips of different lengths also include a fourth water-blocking strip and a fifth water-blocking strip, which are connected to the front flange.

[0009] Furthermore, the four screw seats of the outer water jacket are welded to the screw seat holes of the outer water jacket, wherein the first screw seat hole and the second screw seat hole are at both ends of the fourth water baffle, and the third screw seat hole and the fourth screw seat hole are at both ends of the sixth water baffle.

[0010] The beneficial effects of this utility model are: the water-cooled housing is made entirely of welded steel plates, with a simple structure; it has four water channels, allowing users to freely choose the inlet and outlet directions; the inlet and outlet of the outer water jacket are welded with screw seats, which can be matched with different types of inlet and outlet interfaces; if it is necessary to improve the position of the outlet in the circumferential direction, it is not necessary to redesign the water channel, but only to adjust the length of the third water baffle and the position of the fourth and sixth water baffles, and then adjust the opening position of the screw seat hole on the outer water jacket.

[0014] Figure 4 This is a schematic diagram of the unfolded inner water jacket of this utility model.

[0015] In the figure, the components are: rear flange 1, outer water jacket 2, inner water jacket 3, threaded seat 4, opening 21, opening 22, opening 23, opening 24, inner water jacket cylinder 31, first water-blocking ring 32, second water-blocking ring 33, first water-blocking strip 34, second water-blocking strip 35, third water-blocking strip 36, fourth water-blocking strip 37, fifth water-blocking strip 38, sixth water-blocking strip 39, front flange 40, first threaded seat hole 21, second threaded seat hole 22, third threaded seat hole 23, and fourth threaded seat hole 24. Detailed Implementation

[0016] like Figure 1-3 As shown, the casing is a welded steel plate structure; the outer water jacket has 4 inlet and outlet holes, providing 4 types of water channels; the inlet and outlet of the outer water jacket are welded with screw seats, and standard threads are drilled on the screw seats.

[0017] The water-cooled unit casing consists of a rear flange 1, an outer water jacket 2, an inner water jacket 3, and a threaded seat 4. The threaded seat 4 has standard threads and can be fitted with flanges or water pipes or other inlet / outlet interfaces according to the user's actual needs. Of the four inlet / outlet ports, two are used as inlet / outlet ports, and the other two are plugged with appropriate plugs.

[0018] If the position of the water outlet in the circumferential direction needs to be improved, the water channel does not need to be redesigned. Only the length of the third water-blocking strip 36 and the positions of the fourth water-blocking strip 37 and the sixth water-blocking strip 39 need to be adjusted. Then, the opening position of the screw seat hole on the outer water jacket 2 should be adjusted to ensure that the first screw seat hole 21 and the second screw seat hole 22 are at both ends of the fourth water-blocking strip 37, and the third screw seat hole 23 and the fourth screw seat hole 24 are at both ends of the sixth water-blocking strip 39.

[0019] like Figure 2 As shown, the inner water jacket 3 includes an inner water jacket cylinder 31, a first water-retaining ring 32, a second water-retaining ring 33, several water-retaining strips of different lengths, and a front flange 40; the welding positions of the various components of the inner water jacket 3 are as follows. Figure 4 As shown, the length of the first water-blocking strip 34 is shorter than the distance between the first water-blocking ring 32 and the second water-blocking ring 33. The number of first water-blocking strips 34 is odd, and they are evenly distributed and staggered with the second water-blocking strips 35, welded to the outer surface of the inner water jacket. Two fourth water-blocking strips 37 and the fifth water-blocking strip 38 are cut off from the inner water jacket body 31 at the front flange enclosure to form the cable outlet window.

[0020] The outer water jacket 2 has four screw seat holes. The first screw seat hole 21 and the second screw seat hole 22 are at both ends of the fourth water baffle 37, and the third screw seat hole 23 and the fourth screw seat hole 24 are at both ends of the sixth water baffle 39.

[0021] Four types of water channels in water-cooled housings: 1. The first screw seat hole 21 of the outer water jacket is the water inlet, and the second screw seat hole 22 of the outer water jacket is the water outlet. The other two holes are blocked, and the water inlet and outlet can be interchanged. 2. The first screw seat hole 21 of the outer water jacket is the water inlet, and the third screw seat hole 23 of the outer water jacket is the water outlet. The other two holes are blocked, and the water inlet and outlet can be interchanged. 3. The fourth screw seat hole 24 of the outer water jacket is the water inlet, and the second screw seat hole 22 of the outer water jacket is the water outlet. The other two holes are blocked, and the water inlet and outlet can be interchanged. 4. The fourth screw seat hole 24 of the outer water jacket is the water inlet, and the third screw seat hole 23 of the outer water jacket is the water outlet. The other two holes are blocked, and the water inlet and outlet can be interchanged.
