[0025] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Similar component numbers in the drawings represent similar components. Obviously, the embodiments described below are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0026] It will be understood that when used in this specification and the appended claims, the terms “comprises” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.
[0027] It should also be understood that the terms used in this specification of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the specification of the embodiments of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.
[0028] See also Figure 1-2 The present invention provides a fully covered water channel liquid-cooled servo motor housing, comprising an outer protective housing 1 and an inner water channel housing 2. The outer protective housing 1 is sleeved over the inner water channel housing 2 and sealed therewith. Cooling liquid is supplied to the inner water channel housing 2 through the outer protective housing 1, thereby lowering the temperature of the inner water channel housing 2 and facilitating rapid heat dissipation of the servo motor body located therein.
[0029] See also Figure 2In the present invention, a first water channel structure 3 is provided on the outer circumference of the inner water channel housing 2, wherein the first water channel structure 3 is arranged along the axial direction of the inner water channel housing 2. A plurality of second water channel structures 4 are further provided on one side of the first water channel structure 3. The plurality of second water channel structures 4 are arranged side by side and parallel to the first water channel structure 3 in the axial direction. The first water channel structure 3 and the second water channel structure 4 are evenly arranged on the outer circumference of the inner water channel housing 2. By evenly arranging the first water channel structure 3 and the water channel structure 4 on the circumference of the inner water channel housing, i.e., all around, full coverage of the water channel is achieved, so that the heat generated by the servo motor body can be dissipated more comprehensively and quickly, reducing the possibility of the servo motor body burning out due to incomplete heat dissipation, facilitating the normal progress of work and saving maintenance costs.
[0030] The second water channel structure 4 located between the first water channel structure 3 and the last second water channel structure 4 is sequentially connected end to end with its adjacent second water channel structure 4 or first water channel structure 3 and shares a water channel wall 5. It is understood that the shape and size of the first water channel structure 3 match those of the second water channel structure 4. The arrangement of the first water channel structure 3 and the second water channel structure 4 enables rapid heat dissipation from the inner water channel housing 2, thereby accelerating the rapid heat dissipation of the servo motor body within the inner water channel housing 2. It is understood that multiple second water channel structures 4 are provided on one side of the first water channel structure 3, and the last second water channel structure 4 provided is the aforementioned last second water channel structure 4.
[0031] Please continue reading Figure 2 The wall thickness of the inner water channel shell 2 of the present invention is 7.5-9mm, specifically 8mm. The thickness is not too thick, which is not conducive to heat dissipation, nor is it too thin, which affects the stability of the structure. The depths of the first water channel structure 3 and the second water channel structure 4 are the same or different, and can be set according to actual conditions, as long as the circulation and heat dissipation of the coolant are met, and account for 35-75% of the wall thickness of the inner water channel shell 2, with a large selection range, which can be selected in combination with the heat dissipation effect and product structure strength. Specifically, the depth of the first water channel structure 3 and the second water channel structure 4 is 3.5-4.5mm, specifically 4mm. The depth is neither too deep to affect the stability of the structure, nor too shallow to affect the liquid cooling effect.
[0032] Please continue reading Figure 1A liquid inlet 6 and a liquid outlet 7 are provided at one end on the outer peripheral side of the outer protective shell 1. The liquid inlet 6 is connected to the first water channel structure 3, and the liquid outlet 7 is connected to the last second water channel structure 4, wherein the first water channel structure 3 is not connected to the last second water channel structure 4. In this way, the external liquid cooling supply mechanism can provide liquid for cooling to the inner water channel shell 2 through the liquid inlet 6. The liquid flows from the first water channel structure 3 to the last second water channel structure 4 in sequence and leaves the inner water channel shell 2 through the liquid outlet 7, instead of the coolant entering from the liquid inlet 6 directly flowing out from the liquid outlet 7, which is beneficial to improving the effective utilization rate of the coolant and the heat dissipation efficiency.
[0033] Please continue reading Figure 2 In the circumferential direction of the inner water channel shell 2, the total area of the first water channel structure 3, the second water channel structure and the structure at the connection point accounts for 60-95% of the total area of them and the water channel wall 5. The water flow occupies a larger area of the side area of the inner water channel shell 2, which is conducive to further enhancing the liquid cooling heat dissipation effect.
[0034] Please continue reading Figure 2 A first rounded corner structure 8 is provided on both sides of the water channel wall 5, a second rounded corner structure 9 is provided on the water channel wall 5 at the upper and lower locations of the first water channel structure 3, and a third rounded corner structure 10 is provided on the water channel wall 5 at the upper and lower locations of the second water channel structure 4. The arrangement of the first rounded corner structure 8, the second rounded corner structure 9 and the third rounded corner structure 10 avoids the obstruction of the structure to the water flow, is conducive to the smooth and rapid flow of water, reduces the possibility of stagnant water in the first water channel structure 3 and the second water channel structure 4, and avoids the possibility of damage to the servo motor body due to the lack of liquid circulation and poor heat dissipation effect in a certain place.
