[0038] This utility model provides a water cooling system, which includes a heat exchange module, a water distribution block, and multiple heat exchange execution units. The heat exchange module is equipped with a heat exchanger and has a cold medium interface and multiple sets of hot medium interfaces. Each cold medium interface includes a cold medium inlet and a cold medium return outlet, and each set of hot medium interfaces includes an inlet and a return outlet. The water distribution block's connection port is connected to the hot medium interface via a pipeline, and the water distribution block has multiple sets of interfaces, each set including a medium delivery outlet and a medium return outlet. The heat exchange execution units are installed in the equipment to exchange heat with it. Each heat exchange execution unit is connected to the interface of the water distribution block or the hot medium interface of the heat exchange module via a pipeline. The cold medium interface of the heat exchange module is used to connect an external cooling medium to cool the hot medium flowing from the heat exchange execution units. The water-cooling system includes multiple heat exchange execution units, each of which can be installed in different modules within a cigarette-making machine, allowing for heat exchange with different modules to cool them. After heat exchange, the heated medium in each heat exchange execution unit flows to the hot-cold circulation exchange module for centralized heat exchange. The heated medium is then cooled by the cooling medium connected to the heat exchange execution unit, achieving centralized cooling. The entire system achieves centralized heat exchange through internal and external circulation, resulting in a high degree of centralization. Furthermore, the heat exchange execution units can be added or removed according to actual usage needs to meet the requirements of different cigarette-making machines, offering greater versatility and eliminating the need for separate cooling systems for each cigarette-making machine, thus reducing enterprise costs. Simultaneously, the water-cooling system is highly modular, facilitating installation, maintenance, and disassembly, and allowing for flexible assembly according to cigarette-making equipment.

[0039] Please refer to the following: Figure 1 and Figure 2 In one embodiment, a water cooling system 100 is provided, specifically a water cooling system 100 applied in cigarette equipment, which is mainly used to solve the problem of low integration and modularity of the cooling system of existing cigarette equipment.

[0040] The water cooling system 100 includes a heat exchange module 10, a water distribution block 20, and multiple heat exchange execution units 30. The water cooling system 100 is divided into two lines: an internal circulating water path and an external circulating water path. The heat exchange module 10 is a component in the system used for heat exchange between the internal circulating condensate and the external circulating condensate. The heat exchange execution unit 30 is an execution component in the system used for cooling the equipment. The water distribution block 20 is a component used to divert the internal circulating water. When the water cooling system 100 is in use, each of the heat exchange execution units 30 is installed in the module of the cigarette equipment that needs to be cooled. The heat exchange execution units 30 are in direct or indirect contact with the module in the cigarette equipment. Heat is absorbed by the condensate flowing through the heat exchange execution units 30. Then, the heated water flowing out of each of the heat exchange execution units 30 flows into the heat-cold circulation exchange module 10. The external condensate connected to the heat-cold circulation exchange module 10 exchanges heat with the internal heated water, thereby achieving cooling. That is, the heat generated by each module is transferred through the internal condensate and then through the heat-cold circulation exchange module 10 to the external condensate, thereby achieving cooling.

[0041] The heat exchange module 10 is equipped with a heat exchanger and includes a cold medium interface 11 and multiple sets of hot medium interfaces 12. In this embodiment, "multiple" and "multiple sets" refer to at least two or two sets of interfaces. The cold medium interface 11 is used to connect with external devices to receive external condensate. The cold medium interface 11 includes a first medium inlet and a first medium return outlet. The first medium inlet is used to connect the external condensate into the heat exchange module 10, and the first medium return outlet is used to return the heat-exchanged external condensate to the external devices. The hot medium interfaces 12 are used to connect with the water distribution block 20 or the heat exchange execution unit 30 to receive the heated internal condensate flowing out of the heat exchange execution unit 30. Each set of heat medium interfaces 12 includes a second medium inlet and a second medium return port. The second medium inlet is used for the heated internal condensate to enter the heat exchange module 10, allowing the heated internal condensate to exchange heat with the external condensate. The second medium return port is used for the cooled internal condensate to return to the heat exchange execution unit 30, thereby circulating and cooling the equipment. Since the heat exchange module 10 is provided with multiple heat medium interfaces 12, the heated internal condensate generated by multiple heat exchange execution units 30 can be concentrated in the heat exchange module 10 for centralized heat exchange.

[0042] The water distribution block 20 is provided with a connection interface 21 and multiple sets of conveying interfaces 22. The connection interface 21 includes a first conveying port and a first return port. The first conveying port is connected to the second medium inlet through a pipeline, and the first return port is connected to the second medium return port through a pipeline. That is, the water distribution block 20 and the heat exchange module 10 are connected by at least two pipelines, one for conveying and one for returning, to achieve reciprocating circulation of the liquid medium. Each set of conveying interfaces 22 includes a second conveying port and a second return port. The second conveying port is mainly used to connect with the conveying pipeline to convey the heated internal condensate flowing out of the heat exchange execution unit 30 to the heat exchange module 10. The second return port is mainly used to connect with the return pipeline to convey the cooled internal condensate flowing out of the heat exchange circulation module 10 to the heat exchange execution unit 30.

[0043] The water distribution block 20 may be equipped with two independent water paths: one for cold water and one for warm water. Each delivery port is connected to the warm water path, while each return port is connected to the cold water path. Thus, when the water distribution block 20 is connected to the heat exchange module 10 and the heat exchange execution unit 30, the heated internal condensate flowing from the heat exchange execution unit 30 can flow into the heat exchange module 10 through the warm water path; and the cooled internal condensate flowing from the heat exchange module 10 can flow into the heat exchange execution unit 30 through the cold water path.

[0044] The heat exchange execution unit 30 is installed in the equipment to exchange heat with the equipment. The heat exchange execution unit 30 can be directly or indirectly connected to modules in the equipment to achieve heat exchange. Each heat exchange execution unit 30 is connected to the water distribution block 20 or the heat-cold circulation exchange module 10 via a pipeline, so that the cooling medium (i.e., internal condensate) circulates between the heat exchange execution unit 30 and the heat-cold circulation exchange module 10. In other words, the heat exchange execution unit 30 is connected to the water distribution block 20 or the heat and cold circulation exchange module 10 through at least two pipes. One pipe is a delivery pipe, with one end connected to the outlet of the heat exchange execution unit 30 and the other end connected to the second delivery port of the water distribution block 20 (or the second medium inlet of the heat and cold circulation exchange module 10), thereby transferring the heated internal condensate to the heat and cold circulation exchange module 10. The other pipe is a return pipe, with one end connected to the inlet of the heat exchange execution unit 30 and the other end connected to the second return port of the water distribution block 20 (or the second medium return port of the heat and cold circulation exchange module 10), thereby transferring the cooled internal condensate to the heat exchange execution unit 30.

[0045] The cold medium interface 11 of the heat exchange module 10 is used to connect an external cooling medium (i.e., external condensate) to exchange heat with the heated cooling medium (i.e., heated internal condensate) flowing in from each of the heat exchange execution units 30.

[0046] The water cooling system 100 is equipped with multiple heat exchange execution units 30, each of which is directly or indirectly connected to the heat medium interface 12 of the heat exchange module 10 via pipelines. This allows the heated condensate from each heat exchange execution unit 30 to be centrally transferred to the heat exchange module 10 for heat exchange. By using a single heat exchange module 10 to accommodate multiple heat exchange execution units 30, heat exchange is achieved in a "one-to-many" manner, resulting in a high degree of integration. Furthermore, the heat exchange module 10 has multiple heat medium interfaces 12, and the water distribution block 20 has multiple delivery interfaces 22. Therefore, the specific number of heat exchange execution units 30 can be increased or decreased according to actual needs, improving the versatility of the water cooling system 100. This allows the system to be adapted to different cigarette manufacturing equipment (or different structural forms of the same cigarette manufacturing equipment), reducing enterprise costs. For example, when there are many modules in the cigarette-making equipment that require cooling, the number of heat exchange execution units 30 can be appropriately increased. Each heat exchange execution unit 30 is connected to a different conveying interface 22 on the water distribution block 20 (or directly connected to the heat medium interface 12), thereby centrally exchanging heat between each heat exchange execution unit 30 and the cold and heat circulation exchange module 10. When there are few modules in the cigarette-making equipment that require cooling, the number of heat exchange execution units 30 can be appropriately reduced. After reducing the number of heat exchange execution units 30, the excess conveying interfaces 22 or heat medium interfaces 12 can be sealed by installing plugs. At the same time, the water cooling system 100 has a high degree of modularity, which is convenient for installation, maintenance and disassembly, and can be flexibly assembled according to the cigarette-making equipment.

[0047] The multiple heat medium interfaces 12 in the heat exchange module 10 can be implemented in the following ways: a water distribution block is set in the heat exchange module 10, and multiple interfaces are set on the water distribution block, so that the internal condensate is collected through the water distribution block and then transferred to the heat exchanger in the heat exchange module 10; or multiple heat medium interfaces are directly opened on the heat exchanger in the heat exchange module 10 for direct connection.

[0048] Specifically, in one embodiment, the hot and cold circulation exchange module 10 includes a motor and a water pump, thereby providing power to drive the medium to circulate back and forth, which facilitates the integrated layout of the equipment.

[0049] Preferably, in one embodiment, the hot and cold circulation module 10 is equipped with sensors for flow detection, pressure detection, and temperature detection, which facilitates intelligent control.

[0050] Preferably, in one embodiment, the heat exchange module 10 employs a plate heat exchanger, thereby achieving higher heat transfer efficiency.

[0051] The external condensate is supplied centrally by the enterprise, and its temperature is generally below 20 degrees Celsius, thus requiring no separate refrigeration equipment. Preferably, in one embodiment, the hot and cold water circulation system 10 is equipped with a proportional switching valve. The opening degree of the proportional switching valve can be selected according to the temperature of the external water source. For example, when the external water source temperature is very low, the proportional switching valve opening is small; when the external water source temperature is high but not exceeding 20 degrees Celsius, the proportional switching valve opening is large.

[0052] Preferably, in one embodiment, multiple water distribution blocks 20 are provided, and these multiple water distribution blocks 20 are divided into main water distribution blocks 201 and secondary water distribution blocks 202. The main water distribution block 201 is connected to the heat medium interface 12 via a pipeline. The secondary water distribution block 202 is connected to the main water distribution block 201 via a pipeline, or the secondary water distribution block 202 is connected to the heat medium interface 12 via a pipeline, that is, the secondary water distribution block 202 can be connected to the heat exchange module 10 indirectly or directly. By providing multiple water distribution blocks 20, the number of interfaces can be further increased, allowing for a larger number of heat exchange execution units 30 to be arranged, further meeting the heat dissipation requirements of the cigarette equipment.

[0053] Preferably, in one embodiment, the interfaces of each of the water distribution blocks 20 are of the same type and size. That is, the type of the delivery port (return port) provided on each of the water distribution blocks 20 is the same; for example, the delivery ports on all the water distribution blocks 20 can be threaded interfaces, and the dimensions of the delivery ports (return ports) on each of the water distribution blocks 20 are the same. This facilitates the interchangeability of the water distribution blocks 20 and improves versatility. Due to this high versatility, when a corresponding main water distribution block 201 is not required, the secondary water distribution block 202 connected to this main water distribution block 201 can be disassembled and separated, allowing the secondary water distribution block 202 to directly connect to the hot and cold circulation exchange module 10. Furthermore, the delivery ports and return ports on the same water distribution block 20 can also be of the same type and size, thereby facilitating the connection and installation of pipelines.

[0054] Preferably, in one embodiment, the plurality of heat exchange execution units 30 include a space heat exchanger 31 and a water-cooled plate 32. That is, the plurality of heat exchange execution units 30 include at least two types. The space heat exchanger 31 is mainly used for liquid-gas heat exchange. The space heat exchanger 31 does not directly contact the heat-generating device, but exchanges heat with the air in the space where the heat-generating device is located, thereby reducing the temperature in the space where the heat-generating device is located, achieving indirect cooling. For example, when the heat-generating device is a servo motor, the space heat exchanger 31 does not need to directly contact the servo motor; it only needs to be placed in the chassis where the servo motor is installed to cool the space inside the chassis. The water-cooled plate 32, on the other hand, directly contacts the heat-generating device, achieving direct cooling, which is the most direct and efficient cooling method. For example, the heat-generating device can be directly mounted on the water-cooled plate 32. The water-cooled plate 32 refers to a plate with internal flow channels and an inlet and outlet connected to the flow channels. Condensate flows into the flow channels and exchanges heat with the heat transferred from the external equipment to achieve cooling of the external equipment.

[0055] Preferably, in one embodiment, the pipe interfaces of each heat exchange execution unit 30 are of the same type and size. That is, in this embodiment, the inlets of each heat exchange execution unit 30 can be of the same type, such as a threaded interface. Similarly, the outlets of each heat exchange execution unit 30 can be of the same type, such as a threaded interface. This facilitates the interchangeability of the heat exchange execution units 30; for example, the space heat exchanger 31 and the water-cooled plate 32 can be interchanged. This improves the standardization of the water-cooling system 100, facilitating assembly and maintenance. Furthermore, the inlets and outlets on the same heat exchange execution unit 30 can also use the same type and size, thus facilitating pipe connection and installation. More preferably, in one embodiment, the interface type (and size) of the water distribution block 20 is the same as the interface type (and size) of the heat exchange execution unit 30, further improving standardization and allowing for more flexible installation, facilitating assembly and maintenance.

[0056] Preferably, in one embodiment, the piping in the water cooling system 100 is made of flexible tubing. That is, both the delivery pipe and the return pipe in the water cooling system 100 are made of flexible tubing, which facilitates the routing of the tubing. The flexible tubing can be positioned using pipe clamps to fix the position of the tubing.

[0057] Preferably, in one embodiment, the water cooling system 100 further includes a water supply device 40, which is connected to the heat exchange module 10 via a pipeline. The water supply device 40 is a device for supplying internal condensate. When the internal condensate decreases due to leakage or other reasons, the water supply device 40 can replenish the internal condensate and improve the cooling effect.

[0058] Preferably, in one embodiment, the water distribution block 20 is provided with temperature and pressure detection sensors.

[0059] Preferably, in one embodiment, the water cooling system 100 is provided with an exhaust valve on the pipeline, which can discharge the gas generated in the pipeline and improve the cooling efficiency.

[0060] Meanwhile, in one embodiment, a coiling unit is provided, which incorporates the water-cooling system 100. The water-cooled motor 200 in the coiling unit is connected via pipelines to the water distribution block 20 or the heat exchange medium interface 12 of the heat exchange module 10. That is, the liquid inlet and liquid outlet of the water-cooled motor 200 are directly or indirectly connected via pipelines and corresponding interfaces in the heat exchange medium interface 12. The internal condensate generated by the heated water-cooled motor 200 is also centrally heat-exchanged by the heat exchange module 10.

[0061] Understandably, with technological advancements, the requirements for integration, intelligence, and modularity in cigarette equipment are increasing. Traditional cigarette equipment cooling systems often rely on single-point cooling, resulting in low levels of integration, intelligence, and modularity, unsatisfactory cooling effects, cumbersome equipment movement and disassembly, large space requirements, complex structures, and difficulties in on-site piping layout. Furthermore, they cause significant coolant leakage, making equipment cleaning difficult, polluting the environment, and increasing equipment investment costs. Currently common water-cooling system designs, and water-to-air cooling system designs, are integrated with corresponding modular designs. This approach is complex, involving numerous and convoluted pipes, resulting in a complex structure, large size, high piping costs, and the need for pipe clamps for each pipe, making installation inconvenient and further increasing equipment investment costs.

[0062] The water cooling system 100 provided in this application can effectively solve some problems existing in the prior art and can reduce the cost of the enterprise as much as possible.

[0063] Furthermore, new types of tobacco (heated cigarettes) have become popular abroad in recent years, and there is currently no dedicated equipment for heated cigarette production in China. To adapt to this new situation and meet the future large-scale production needs of major domestic tobacco companies, the applicant has developed heated cigarette production equipment. Since heated cigarettes involve different process flows, each requiring different equipment configurations, the applicant has designed a heated cigarette production system that adopts a modular design principle to facilitate convenient and quick assembly of different equipment configurations by production enterprises, thereby meeting the diverse process flows of new tobacco products. In contrast, if existing cooling solutions are used, a separate water-cooling system would be required for each production line with different process flows, significantly increasing costs for enterprises.

[0064] Therefore, this application designs a distributed, modular water-cooling system 100, adopting a centralized and unified water-cooling supply mode, which facilitates installation, maintenance, and disassembly, offers more flexible layout, and has a high degree of integration and intelligence. By configuring and combining different modules, it can perfectly adapt to different unit process flows. It can quickly configure a water-cooling system that meets the cooling requirements according to different new tobacco process flows, facilitating the assembly of complete sets of equipment.

[0065] In other words, in one embodiment, the water cooling system 100 is used in a cigarette-making and sealing unit for heating cigarettes, and is a cooling system for cigarette-making and sealing units that are adapted to different process flow routes.

[0066] Preferably, in one embodiment, the pipe interfaces of each water-cooled motor 200 in the coiling unit are of the same type and size. That is, in this embodiment, the liquid inlets of each water-cooled motor 200 can also be of the same type, such as threaded interfaces. Similarly, the liquid outlets of each water-cooled motor 200 can also be of the same type, such as threaded interfaces. This improves standardization and facilitates assembly and maintenance. More preferably, the type and size of the pipe interfaces of the water-cooled motor 200 can be the same as the interface type and size of the water distribution block 20.

[0067] Preferably, in one embodiment, the servo control module inside the electrical cabinet of the coiling machine is directly mounted on the water-cooled plate 32, thereby providing the most direct cooling for the servo control module and maximizing cooling efficiency. More preferably, in one embodiment, the servo control module inside the electrical cabinet is directly mounted on the water-cooled plate and fixed by a T-slot.

[0068] Specifically, in one embodiment, two main water distribution blocks 201 are provided, namely a first main water distribution block 2011 and a second main water distribution block 2012. The first main water distribution block 2011 and the second main water distribution block 2012 are respectively connected to the hot and cold circulation exchange module 10. Three secondary water distribution blocks 202 are provided, namely a first water distribution block 2021, a second water distribution block 2022, and a third water distribution block 2023. The first water distribution block 2021 is connected to the first main water distribution block 2011, the second water distribution block 2022 is connected to the second main water distribution block 2021, and the third water distribution block 2023 is connected to the second water distribution block 2022.

[0069] The internal condensate flowing from the heat exchange module 10 is divided into two paths. One path flows into the first main water distribution block 2011, which then distributes it to the twisting module, filter section module, and first electrical control cabinet of the coiling unit. The twisting module is equipped with multiple space heat exchangers 31 and a high-power water-cooled motor 200. The internal condensate flowing into the twisting module first flows into the first water distribution block 2021, and then through the first water distribution block 2021 flows into each of the space heat exchangers 31 and the high-power water-cooled motor 200 for heat exchange. The filter section module is equipped with a space heat exchanger 31, and the internal condensate flowing into the filter section module flows into the space heat exchanger 31 for heat exchange. The first electrical control cabinet is equipped with a water-cooled plate 32 and a radiator, and the internal condensate flowing into the electrical control cabinet flows into each of the water-cooled plate 32 and the radiator for heat exchange. The first electrical control cabinet can be mainly used to control the twisting module and the filter section module. Another internal condensate flows into the second main water distribution block 2012, which then branches out to the pre-jointing module, the base rod module, and other electrical control cabinets and power cabinets. The internal condensate branching out from the second main water distribution block 2012 flows directly or indirectly (through the second water distribution block 2022 and the third water distribution block 2023) into the cooling execution units (e.g., space heat exchanger 31, water-cooled plate 32, radiator, water-cooled motor 200) arranged in each module.

[0070] The base rod module is responsible for cutting, conveying, and shifting a type of base rod. In heated cigarettes, the base rod can be a functional section such as a cooling section, a hollow section, or a smoke-generating section. The number of base rod modules in a cigarette-making unit will vary depending on the different process flows; that is, the number of base rod modules will differ depending on the type of cigarette-making unit.

[0071] The pre-twisting module is a module that twists together the base rods except for the filter section to form a composite base rod. This module is also set according to different process flows. When there are multiple base rod modules, the pre-twisting module will be set in the coiling unit.

[0072] The filter tip section module is responsible for cutting, conveying, and shifting the filter tip section. It is usually a basic module that is set up in various process flows.

[0073] The twisting module is a module that twists the filter tip section and the base rod (or the pre-twisted composite base rod) together. It is usually a basic module that is set up in various process flows.

[0074] The drums that transfer the base rod in the base rod module, pre-jointing module, filter section module, and jointing module are all driven by servo motors. The space heat exchanger 31 mainly dissipates the heat generated by the servo motors. The radiator is mainly used to dissipate the heat generated by the various electrical components in the electrical control cabinet. To further improve the heat exchange efficiency in the electrical control cabinet, a fan can be installed inside the cabinet, with the fan facing the water-cooled plate 32. The fan blows hot air onto the water-cooled plate 32, thereby further improving the cooling effect in the electrical control cabinet through gas-liquid heat exchange.

[0075] In one embodiment, the first main water distribution block 2011, the first water distribution block 2021, and the space heat exchanger 31, the water-cooled plate 32, and the radiator disposed in the filter section module and the joint module of the water cooling system 100 can serve as basic layout components, while other components can be added or removed according to the actual process flow equipment. Corresponding water cooling modules can be quickly configured according to different process flows. If a channel is not needed in the equipment configuration, it can be directly cancelled by installing a plug at the interface of the water distribution block 20.

[0076] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
