Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cigarette making machine auxiliary tools, and in particular to a water cooling device for a cigarette making machine bypass fan controller. Background Art
[0002] The cigarette making machine is an important production equipment in the production process of cigarette factories. It is used for processing techniques such as tobacco rod molding. Among them, the bypass fan provides negative pressure for the molding of tobacco rods. Under the control of the controller, the bypass fan supplies negative pressure according to the process progress. Since the cigarette making machine has to run continuously for a long time, the inside of the bypass fan controller will generate more heat. In order to ensure the normal operation of each component, the heat generated inside the bypass fan controller must be dissipated in time. The current heat dissipation method is to open heat dissipation holes on the outer casing of the bypass fan controller and dissipate heat through the heat dissipation fan inside the outer casing. However, the heat dissipation efficiency and stability of the heat dissipation fan of the original bypass fan controller are low, and the heat dissipation effect inside the bypass fan controller is poor. Excessive heat accumulation inside the bypass fan controller is likely to cause the internal temperature to rise, which not only affects the service life of the components, but also causes an increase in the equipment failure rate, which is easy to have a negative impact on the overall production progress. Utility Model Content
[0003] The purpose of the present application is to provide a water-cooled heat dissipation device for a bypass fan controller of a cigarette making machine. The heat dissipation device can be installed on the housing of the controller to effectively dissipate the heat inside the controller through the controller housing, thereby effectively solving the deficiencies existing in the prior art.

[0005] There are multiple heat sinks, each of which is provided with an attachment surface, and the heat sink is in contact with the controller housing through the attachment surface;
[0006] The heat dissipation pipeline has an outlet end and an inlet end, and a portion of the heat dissipation pipeline between the outlet end and the inlet end passes through each heat dissipation fin in sequence;
[0007] Wherein, the heat sink and the outer sides of the corresponding parts of the heat dissipation pipeline are in contact with each other.

[0010] In a possible implementation, both ends of the accommodating groove along the direction are located at the edge side of the heat sink.
[0011] In a possible implementation, the accommodating groove is arranged in a continuous U-shaped bend.
[0012] In a possible implementation, the accommodating grooves on each of the heat sinks are disposed at the same position.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0022] like Figure 1-Figure 3 As shown, the embodiment of the present application provides a water-cooled heat dissipation device for a bypass fan controller of a cigarette making machine. Due to the long-term operation of the cigarette making machine, the internal components of the bypass fan controller generate a lot of heat, and the heat dissipation of the controller is mostly completed by a cooling fan provided by the factory. A heat dissipation hole is opened on the outer casing of the controller, and the cooling fan is arranged inside the outer casing of the controller. When the cooling fan is running, air is circulated through the heat dissipation holes on the outer casing to achieve the purpose of heat dissipation. However, since the cooling efficiency of the cooling fan provided by the controller when it leaves the factory is low, and the stability of the cooling fan is also poor, the heat dissipation effect on the inside of the controller is poor, and the heat in the outer casing of the controller cannot be dissipated in time, causing the temperature in the controller to rise, which in turn affects the life of the components in the controller, and also causes the failure rate of the controller to increase, which is easy to affect the overall production progress of the workshop. Since the outer casing of the controller is made of metal, the water-cooled heat dissipation device of the present application is arranged on the outer casing of the controller by utilizing the high heat transfer efficiency of the metal material to cool the outer casing of the controller, thereby achieving the purpose of cooling the air inside the outer casing.
[0023] The water-cooled heat dissipation device includes a heat sink 100 and a heat dissipation pipeline 200. There are multiple heat sinks 100, and each heat sink 100 is provided with an attachment surface 101. The heat sink 100 can contact the housing of the controller through the attachment surface 101. Under the action of heat transfer, the heat on the housing of the controller is transferred to the heat sink 100. The heat dissipation pipeline 200 has an outlet end 201 and an inlet end 202. The part of the heat dissipation pipeline 200 between the outlet end 201 and the inlet end 202 passes through each heat sink 100 in turn, and the outer sides of the corresponding parts of the heat sink 100 and the heat dissipation pipeline 200 are in contact with each other, so that the heat on the heat sink 100 is dissipated through the heat dissipation pipeline 200. By connecting the inlet end 202 to the supply end of the cooling medium and connecting the outlet end 201 to the return end of the cooling medium, the heat on the heat sink 100 is dissipated. The cooling medium is connected so that it can flow in the heat dissipation pipeline 200, thereby achieving the purpose of heat dissipation of the controller casing. Preferably, the cooling medium flowing in the heat dissipation pipeline 200 is cooling water, which is conducive to reducing costs. The inlet end 202 of the heat dissipation pipeline 200 is connected to the cooling water supply port, and the outlet end 201 of the heat dissipation pipeline 200 is connected to the cooling water return port to realize the circulation of cooling water in the heat dissipation pipeline 200, continuously cool the casing of the cigarette machine bypass fan controller, and cooperate with the internal heat dissipation fan to effectively improve the cooling effect inside the controller, which is conducive to maintaining the internal environment of the controller at a low temperature, so that the components inside the controller can operate in a better low temperature environment, which is conducive to improving the operating life of the components, and is conducive to reducing the failure rate of various components of the controller, avoiding adverse effects on the production progress of the cigarette factory.
[0024] In this embodiment, the heat sink 100 is attached to the outer surface of the controller housing, and the heat dissipation pipe 200 passes through the heat sink 100 and contacts the heat sink 100, so that the heat in the controller is first transferred to the controller housing, and then the heat is transferred to the heat sink 100, and then the heat is transferred to the cooling water via the heat dissipation pipe 200.
[0025] Preferably, the heat sink 100 is in the shape of a flat plate, and the heat sink 100 as a whole is a thin flat plate structure. One side of the heat sink 100 constitutes an attachment surface 101 of the heat sink 100. In terms of thickness, the heat sink 100 has an inner side and an outer side, and the inner side of the heat sink 100 is the attachment surface 101.
[0026] More preferably, a receiving groove 102 is provided on the attachment surface 101 of the heat sink 100, and the receiving groove 102 is used to receive the heat dissipation pipeline 200, and the heat dissipation pipeline 200 passes through the receiving groove 102, and the heat dissipation pipeline 200 and the groove wall of the receiving groove 102 are in contact with each other, that is, the heat dissipation pipeline 200 and the heat sink 100 are in contact with each other. For example, the receiving groove 102 can be a channel-type structure located inside the heat sink 100, and the channel-type structure is bent in the plane where the heat sink 100 is located to increase the area of heat exchange. Preferably, the receiving groove 102 is an open groove structure, and the depth of the receiving groove 102 is The outer diameter of the heat dissipation pipe 200 is the same as that of the receiving groove 102, that is, a groove is formed on the attachment surface 101 of the heat sink 100, and along the length of the groove, both ends of the receiving groove 102 are located on the edge side of the heat sink 100. More preferably, the heat sink 100 is a rectangular flat plate, and both ends of the receiving groove 102 are located on the same side of the edge of the heat sink 100, which is convenient for the layout and connection between each heat sink 100. Moreover, the direction and shape of the heat dissipation pipe 200 are the same as the direction of the receiving groove 102 on the heat sink 100, which is convenient for directly squeezing the heat dissipation pipe 200 into the receiving groove 102 from the side. , easy to install, the depth of the receiving groove 102 is the same as the outer diameter of the heat dissipation pipe 200 therein, so when the heat dissipation pipe 200 is placed in the receiving groove 102, the heat dissipation pipe 200 and the attachment surface 101 of the heat sink 100 are kept flush, so that a part of the heat dissipation pipe 200 can be in direct contact with the outer surface of the controller shell, which is beneficial to improve the heat dissipation efficiency. As shown in the figure, the partial structure of the heat dissipation pipe 200 and the heat sink 100 in the cross-sectional direction is shown. The top of the heat dissipation pipe 200 is flush with the attachment surface 101 of the heat sink 100, and the bottom shape of the receiving groove 102 is consistent with the heat dissipation pipe 200. The bottom shape of the accommodating groove 102 is adapted to increase the mutual contact area between the heat dissipation pipe 200 and the heat sink 100, which is beneficial to improve the heat dissipation efficiency. Preferably, the width of the opening of the accommodating groove 102 can be slightly smaller than the bottom width of the accommodating groove 102. For example, the width difference between the two positions is 1 mm. The bottom width of the accommodating groove 102 is adapted to the outer diameter of the heat dissipation pipe 200. In this way, the combination stability between the heat sink 100 and the heat dissipation pipe 200 can be improved, and the heat dissipation pipe 200 can be prevented from accidentally falling out. When installing the heat dissipation pipe 200 into the accommodating groove 102, a little force is applied to squeeze the heat dissipation pipe 200 into the accommodating groove 102.
[0027] In this embodiment, the direction of the receiving groove 102 on the heat sink 100 is set in a continuous U-shaped bend, which increases the length of the heat dissipation pipeline 200 in each heat sink 100, which is beneficial to improve the efficiency of heat transfer. More preferably, the setting position of the receiving groove 102 on each heat sink 100 is the same, which is convenient for the connection layout of each heat sink 100.
[0028] Preferably, there are two heat sinks 100, and the settings of the accommodating grooves 102 on the two heat sinks 100 are the same. The two heat sinks 100 can be located in the same plane so that the two heat sinks 100 can be attached to the same side of the controller housing. The two heat sinks 100 may not be located in the same plane. For example, the two heat sinks 100 are perpendicular to each other so that the two heat sinks 100 can be attached to two adjacent sides of the controller housing. A mounting component can also be provided on the heat sink 100, and the heat sink 100 is connected to the controller housing through the mounting component. In one example, the mounting component is a waist hole 300 that penetrates the heat sink 100 in the thickness direction. The waist hole 300 has a certain length, which is convenient for connection with the help of screws, etc., and the position can also be adjusted under the action of the waist hole 300, which is more convenient to use.
[0029] The heat dissipation pipe 200 between the two heat sinks 100 can be a flexible pipe or a rigid pipe. When the heat dissipation pipe 200 between the two heat sinks 100 is a flexible pipe, it is convenient to adjust the positions of the two heat sinks 100. When the heat dissipation pipe 200 between the two heat sinks 100 is a rigid pipe, it is beneficial to improve the integrity of the component.
[0030] More preferably, the heat dissipation pipeline 200 is an integrated pipeline, and the two ends of the integrated pipeline are respectively an inlet end 202 and an outlet end 201, and the middle part of the pipeline includes a plurality of built-in sections 203, and the direction of the built-in sections 203 is adapted to the direction of the receiving grooves 102 on the heat sink 100. At that time, the built-in sections 203 are adapted to the receiving grooves 102 of the heat sink 100, and the portion between adjacent built-in sections 203 is a connecting section 204, which is located between two adjacent heat sinks 100. The heat dissipation pipeline 200 and the heat sink 100 are both made of metal. In this way, the integrity of the components is improved, and the mutual coordination and connection between the heat sink 100 and the heat dissipation pipeline 200 are facilitated, and the direction and shape of the heat dissipation pipeline 200 can be prefabricated according to the relative position of the heat sink 100.
[0031] The working principle of the present application is as follows: taking two heat sinks 100 as an example, two heat sinks 100 are respectively connected to the two built-in sections 203 on the heat dissipation pipe 200, so that the two heat sinks 100 are in the same plane, and then the two heat sinks 100 are connected to the outer casing of the controller through the waist holes 300 on the heat sink 100, so that the attachment surface 101 of the heat sink 100 and the outer casing of the controller are in contact with each other, and the inlet end 202 and the outlet end 201 of the heat dissipation pipe 200 both extend outward from the heat sink 100, and the outlet end 201 and the inlet end 202 are respectively connected to the cooling water return pipe and the cooling water supply pipe, so that the cooling water forms a circulation, and the controller can be cooled.
