Description

Technical Field

[0001] The utility model relates to the technical field of speed regulating motors, in particular to a speed regulating motor with good heat dissipation function. Background Art

[0002] A speed-regulating motor is a motor that changes its speed by changing the motor's level, voltage, current, frequency, etc., so that the motor can achieve higher performance.

[0003] The speed regulating motor will inevitably generate heat when it is running. The traditional speed regulating motor is to install a heat dissipation blade at the rear end of the shaft. When the speed regulating motor is running, the heat dissipation blade is synchronously driven to rotate, driving the air flow to dissipate the heat of the casing. However, when the speed regulating motor is running at a low speed, the heat dissipation blade rotates slowly, resulting in the speed regulating motor being too hot in this state. Therefore, a heat dissipation solution has emerged on the market, which is to install an independent fan at the rear end of the speed regulating motor. When the speed regulating motor is in a low speed state, the fan still maintains an efficient heat dissipation effect.

[0004] At this time, the air driven by the fan is air at normal temperature. Therefore, in some high temperature environments, the heat dissipation effect is still not good. Based on this, a speed regulating motor with good heat dissipation function is provided. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 In an embodiment of the utility model, a speed regulating motor with good heat dissipation function includes a speed regulating motor body 1, a heat dissipation component 2 is installed at the tail end of the speed regulating motor body 1, and the heat dissipation component 2 is used to blow air on the surface of the speed regulating motor body 1 to achieve efficient heat dissipation of the speed regulating motor body 1; the heat dissipation component 2 includes a blowing unit, a cooling unit and a filtering unit; the blowing unit is used to blow air to make it flow, and the surface of the speed regulating motor body 1 is dissipated by the flowing air; the cooling unit is used to cool the air entering the blowing unit; the filtering unit is used to filter dust from the air entering the blowing unit.

[0021] The blowing unit includes a fixed cover 201 and a fan 202; the fixed cover 201 is installed and sleeved on the outer side of the tail of the speed regulating motor body 1 by screws, and a raised mounting block 3 for installing the fixed cover 201 is fixed at a position close to the outside of the outer side of the speed regulating motor body 1, and screw holes for tightening the screws are provided on the raised mounting block 3, and the fixed cover 201 is used to provide installation support for the fan 202; the fan 202 is fixed to the inner side of the fixed cover 201 by a bracket, and the operation of the fan 202 can blow air toward the speed regulating motor body 1 to achieve heat dissipation of the outer wall of the speed regulating motor body 1.

[0022] The cooling unit includes a cooling water circulation tube segment 204, a water inlet seat 205, a water inlet hole 206, a drain seat 207, and a drain hole 208; the cooling water circulation tube segment 204 is installed on the inner side of the fixed cover 201 and is located at the end of the fan 202 away from the speed regulating motor body 1, and both sides of the cooling water circulation tube segment 204 extend to both sides of the outside of the fixed cover 201 and are respectively connected and conducted with the water inlet seat 205 and the drain seat 207; the water inlet hole 206 and the drain hole 208 are respectively fixed on one side of the outer wall of the water inlet seat 205 and the drain seat 207, and the water inlet hole 206 and the drain hole 208 are connected with the external cooling water tank through a hose and a circulating pump. The cooling water flows in the cooling water circulation tube segment 204 and performs heat exchange reaction with the air entering the inner cavity of the fixed cover 201, thereby realizing the cooling operation of the air in the inner cavity of the fixed cover 201.

[0023] The filter unit includes a filter screen cover 203 , which is sleeved and installed on the rear end of the fixed cover 201 . The air entering the inner cavity of the fixed cover 201 from the filter screen cover 203 passes through the filter screen cover 203 to filter dust.

[0024] In this embodiment: when the speed regulating motor is running, the fan 202 can be started synchronously. The fan 202 generates suction to suck external air from the direction of the filter cover 203 into the fixed cover 201, and blows it from the front end of the fixed cover 201 to the speed regulating motor body 1. The flowing air contacts the outer shell surface of the speed regulating motor body 1 to absorb heat, thereby realizing the heat dissipation operation of the speed regulating motor body 1.

[0025] If the external ambient temperature is high, the circulating pump for conveying cooling water can be started. The water pump conveys the cooling water to the water inlet seat 205 through the water inlet hole 206, and then diverts it to the inside of multiple cooling water circulation tube sheets 204. At this time, the air entering the fixed cover 201 exchanges heat with the cooling water inside the cooling water circulation tube sheet 204, and the air temperature in the fixed cover is reduced. The cooling water after heat exchange is discharged through the drain seat 207 and the drain hole 208 (it should be supplemented that the water inlet seat 205, the cooling water circulation tube sheet 204, and the drain seat 207 are all hollow structures for providing space for the flow of cooling water. It should also be noted that this scheme is mainly aimed at the structural improvement of the heat dissipation component 2, so the secondary cooling structure of the cooling water is not repeated). At this time, when the cooled air blows to the surface of the speed regulating motor body 1, it can better absorb heat from it, further improving the cooling efficiency and effect of the speed regulating motor body 1, so that the speed regulating motor can maintain a low operating temperature even in a high temperature environment.

[0026] Please refer to Figures 1-2 The outer wall of the speed regulating motor body 1 is formed with a heat sink, the outer diameter of the distribution track of the multiple raised mounting blocks 3 matches the inner diameter of the fixed cover 201 and is larger than the outer wall diameter of the speed regulating motor body 1, and the inner diameter of the fixed cover 201 is smaller than the distribution outer diameter of the heat sink.

[0027] In this embodiment: through this structure, the air blown out from the front end of the fixed cover 201 can enter the gaps between the multiple heat sinks, so that the flowing air is fully in contact with the heat sinks, achieving the best heat dissipation effect.

[0028] Please refer to Figures 2 to 4 There are multiple cooling water circulation segments 204, and the cooling water circulation segments 204 are located inside the fixed cover 201 and have an "Ω"-shaped structure. The diameters of the multiple cooling water circulation segments 204 increase successively and are arranged in a sleeve-connected manner from the inside to the outside.

[0029] In this embodiment, the cooling water circulation tube segments 204 with a plurality of “Ω”-shaped structures have a larger contact area between the air and the cooling water circulation tube segments 204 than a tube segment structure with a straight strip state, thereby achieving efficient air cooling operation.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
