[0002] The cleaning machine is used to flush and filter the pollutants generated or invaded during the manufacturing, assembly, use and maintenance of the hydraulic system; it can also be used for regular maintenance and filtration of working oil to improve cleanliness, avoid or reduce failures caused by contamination, thereby ensuring the high performance, high reliability and long life of hydraulic system equipment.

[0003] In order to save energy and reduce volume and weight, the new generation of water pumps uses permanent magnet synchronous motors as power, and they require a controller to drive them. In order to achieve waterproofing, the controller is in a sealed state. When the motor is running, it drives the fan to dissipate heat for it, but it can only dissipate heat for the power semiconductor devices of the controller. The internal large-capacity capacitor cannot dissipate heat. When the water pump works continuously, the temperature of the capacitor will slowly rise, and even exceed the temperature limit that the capacitor can withstand. This situation will damage the capacitor and the controller will not work. Moreover, even if the capacitor is not damaged, its long-term high temperature state will affect its life. The higher the temperature of the capacitor when it is working, the shorter its life.

[0004] In order to solve the above problems, we propose a heat dissipation structure which is special for cleaning agents and has excellent heat dissipation effect. Utility Model Content

The heat conducting pipe is arranged on the outer surface of the heat dissipation sleeve, and the protective shell is arranged on a side of the heat conducting pipe away from the heat dissipation sleeve.

[0009] Wherein, the heat dissipation protection component further includes a circular hole and a material-saving groove, the circular hole is arranged inside the protective shell, and the material-saving groove is fixedly connected to the protective shell and is located on the outer surface of the protective shell.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] First embodiment

[0020] See also Figure 1 to Figure 3 , Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 It is a front view of the whole of the first embodiment of the utility model. Figure 3 This utility model Figure 2 A magnified view of the local structure at A.

[0021] The utility model provides a heat dissipation structure, including an inner sleeve 101 and a heat dissipation protection component, wherein the heat dissipation protection component includes a heat dissipation hole 102, a positioning groove 103, a chamfered groove 104, a heat conductive sleeve 105, a heat dissipation sleeve 106, a heat conductive pipe 107, a protective shell 108, a circular hole 109 and a material saving groove 110. The above-mentioned scheme solves the problem that when the water pump works continuously, the temperature of the capacitor will slowly rise, and even exceed the temperature limit that the capacitor can withstand. This situation will damage the capacitor and the controller will not work. Moreover, even if the capacitor is not damaged, it will be in a high temperature state for a long time, which will affect its life. The higher the temperature of the capacitor when it is working, the shorter the life. It can be understood that the above-mentioned scheme can be used to set the inner sleeve 101 on the outer surface of the motor when the motor of the detergent needs to be cooled. The heat will then be collected and discharged by the heat dissipation holes 102, and the discharged heat will be absorbed by the heat-conducting sleeve 105 and conducted to the heat-dissipating sleeve 106, and the heat-dissipating sleeve 106 will form a simple heat cycle exchange structure with the heat-conducting pipe 107, thereby keeping the temperature of the motor at a constant temperature for a long time, and the heat-conducting pipe 107 will discharge the excess heat through the circular holes 109 on the protective shell 108, thereby actively and effectively solving the problem that when the water pump works continuously, the temperature of the capacitor will slowly rise, and even exceed the temperature limit that the capacitor can withstand, which will damage the capacitor and the controller will not work, and even if the capacitor is not damaged, it will be in a high temperature state for a long time, which will affect its lifespan, and the higher the temperature of the capacitor when it works, the shorter its lifespan.

[0022] According to this specific embodiment, the heat dissipation hole 102 is arranged inside the inner sleeve 101, the positioning groove 103 is arranged in the center of the outer surface of the inner sleeve 101, and the chamfered groove 104 is arranged at one end inside the inner sleeve 101. The inner sleeve 101 is a structural connection component connected to the motor of the cleaning machine, and the heat dissipation hole 102 is an important functional cavity-type component for performing heat dissipation operations. The positioning groove 103 is an identification-type structural component that facilitates the staff to install the inner sleeve 101, and the chamfered groove 104 is a functional structural component that facilitates the staff to install the inner sleeve 101.

The thermally conductive sleeve 105 is an important conductive structural component that absorbs the heat discharged from the heat dissipation holes 102. At the same time, the heat dissipation sleeve 106 will be an important functional component that forms a simple heat circulation exchange structure with the heat pipe 107.

[0024] Secondly, the heat pipe 107 is arranged on the outer surface of the heat dissipation sleeve 106, and the protective shell 108 is arranged on the side of the heat pipe 107 away from the heat dissipation sleeve 106. The heat pipe 107 will be an important component for forming a heat circulation exchange structure, and after forming a simple heat exchange structure, the heat pipe 107 will effectively keep the temperature of the motor at a constant temperature for a long time, and the protective shell 108 is an auxiliary structural component for protecting the whole.

[0025] At the same time, the circular hole 109 is arranged inside the protective shell 108, and the material-saving groove 110 is fixedly connected to the protective shell 108 and is located on the outer surface of the protective shell 108. The circular hole 109 is used to discharge excess heat in the heat pipe 107, thereby maintaining a stable simple heat exchange structure, and the material-saving groove 110 is used to reduce unnecessary manufacturing materials of the protective shell 108, thereby reducing production costs.

[0026] When the utility model is used to dissipate heat for the motor of the detergent, the inner sleeve 101 is sleeved on the outer surface of the motor, and then the heat is collected and discharged by the heat dissipation holes 102, and the discharged heat is absorbed by the heat-conducting sleeve 105 and conducted to the heat-dissipating sleeve 106, and the heat-dissipating sleeve 106 and the heat-conducting pipe 107 form a simple heat circulation exchange structure, thereby keeping the temperature of the motor at a constant temperature for a long time, and the heat-conducting pipe 107 will discharge the excess heat through the circular hole 109 on the protective shell 108, thereby actively and effectively solving the problem that when the water pump works continuously, the temperature of the capacitor will slowly rise, and even exceed the temperature limit that the capacitor can withstand, which will damage the capacitor and the controller will not work. Moreover, even if the capacitor is not damaged, it will be in a high temperature state for a long time, which will affect its life. The higher the temperature of the capacitor when it works, the shorter its life.
