Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, and in particular to a cooling structure and a machine tool cooling system having the same. Background Art

[0002] In modern industrial production, the stability and accuracy of high-end CNC machine tools and other precision equipment are the key to manufacturing high-quality parts. However, during the operation of the machine tool, the heat generated by the spindle rotation, guide screw movement, and cutting process will cause thermal deformation of the machine tool structure, thereby affecting the processing accuracy and the service life of the equipment. According to statistics, the error caused by thermal deformation of the machine tool accounts for about 60% of the total error of the machine tool. Therefore, effective thermal management is essential to ensure the performance of the machine tool.

[0003] At present, the cooling technologies used to eliminate thermal deformation of machine tools mainly include water cooling and oil cooling. When water is used as a cooling medium, it has a large specific heat capacity and can quickly absorb heat, so it is often used to cool the hydraulic system of machine tools and some parts that do not require lubrication. When oil is used as a cooling medium, due to its high boiling point and good lubricity, it is suitable for cooling spindles, guide rails and other parts that need to be cooled and lubricated at the same time.

[0037] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] In modern industrial production, the stability and accuracy of high-end CNC machine tools and other precision equipment are the key to manufacturing high-quality parts. However, during the operation of the machine tool, the heat generated by the spindle rotation, guide screw movement, and cutting process will cause thermal deformation of the machine tool structure, thereby affecting the processing accuracy and the service life of the equipment. According to statistics, the error caused by thermal deformation of the machine tool accounts for about 60% of the total error of the machine tool. Therefore, effective thermal management is essential to ensure the performance of the machine tool.

[0039] At present, the cooling technologies used to eliminate thermal deformation of machine tools mainly include water cooling and oil cooling. When water is used as a cooling medium, it has a large specific heat capacity and can quickly absorb heat, so it is often used to cool the hydraulic system of machine tools and some parts that do not require lubrication. When oil is used as a cooling medium, due to its high boiling point and good lubricity, it is suitable for cooling spindles, guide rails and other parts that need to be cooled and lubricated at the same time. However, existing coolers can usually only use one cooling medium, namely water or oil, and different coolers need to be configured for different heat-generating components, which not only increases the equipment cost, but also takes up more production space and reduces the flexibility of equipment layout.

[0040] The main purpose of the present invention is to provide a cooling structure and a machine tool cooling system having the same, so as to solve the problem in the prior art that when a machine tool is cooled using a variety of cooling media, a plurality of cooling machines need to be equipped.

[0041] First, the present application provides a cooling structure, including a heat exchanger 1, wherein the heat exchanger 1 has a relatively independent first heat exchange pipe and a second heat exchange channel, and both ends of the first heat exchange channel are used to connect with a component to be cooled, so as to input a cooling medium into the component to be cooled to cool the component to be cooled, and the cooling medium after cooling the component to be cooled is passed through the second heat exchange channel for heat exchange;

[0042] The first heat exchange channel includes a relatively independent first flow channel 2 and a second flow channel 3, so that two different cooling media can flow in the first flow channel 2 and the second flow channel 3 respectively;

[0043] A cooling component, the inlet and outlet of the cooling component are used to communicate with the two ports of the second heat exchange channel to input refrigerant into the second heat exchange channel to cool the cooling medium in the first heat exchange channel.

[0044] Specifically, Figure 1 and Figure 2 As shown, a cooling structure provided in the present application includes a heat exchanger 1, which has a first heat exchange channel and a second heat exchange channel which are relatively independently arranged, wherein the two ports of the first heat exchange channel are respectively used to connect with the components to be cooled, so as to transport the cooling medium into the components to be cooled through the first heat exchange channel, thereby cooling the components to be cooled by the cooling medium, and the cooling medium after cooling the components to be cooled is heat exchanged with the components through the second heat exchange channel. The first heat exchange channel in the present application includes a first flow channel 2 and a second flow channel 3 which are relatively independently arranged, so that two different cooling media flow in the first flow channel 2 and the second flow channel 3 respectively, and the two ports of the second heat exchange channel are connected with the cooling component to transport the refrigerant into the second heat exchange channel, thereby heat exchange cooling of the two different cooling media in the first heat exchange channel, and the two different cooling media are water and oil respectively.

[0045] The first flow channel 2 and the second flow channel 3 in the first heat exchange channel are used for the circulation of water and oil respectively. Due to the different thermophysical properties of water and oil, water has a large specific heat capacity and is suitable for quickly absorbing a large amount of heat, while oil has good thermal conductivity and a high boiling point and is suitable for stable cooling in a high temperature environment. This design enables the cooling structure to optimize cooling according to the characteristics of different components, thereby improving the overall cooling efficiency.

[0046] In the first heat exchange channel, water and oil circulate through independent flow channels respectively, avoiding direct heat exchange between the two media, so that the temperature of each cooling medium can be independently controlled.

[0047] Traditional cooling systems usually require multiple cooling devices to cool water and oil respectively, while the cooling structure of the present application integrates the cooling of the two media into one heat exchanger 1, reducing the number of cooling devices, simplifying the system structure, and reducing the equipment purchase cost and operation and maintenance cost.

[0048] The design of the first heat exchange channel of the present application enables the cooling structure to flexibly adjust the type and flow rate of the cooling medium according to actual usage conditions to adapt to the cooling requirements of different machine tool components.

[0049] In summary, the cooling structure of the present application significantly improves the cooling efficiency through its unique dual-channel design, and enhances the flexibility, stability and economy of the cooling structure.

[0050] Furthermore, the cooling structure further comprises: a partition 4, which is arranged in the first heat exchange channel to divide the first heat exchange channel into a first flow channel 2 and a second flow channel 3;

[0051] Wherein, the thickness of the partition 4 is 1.9 mm to 2.1 mm; and / or,

[0052] The inner diameter of the first heat exchange channel is 19 mm.

[0053] Specifically, the cooling structure in the present application also includes a partition 4 arranged in the first heat exchange channel, and the partition 4 is arranged in the middle position of the first heat exchange channel to divide the first heat exchange channel into a first flow channel 2 and a second flow channel 3 along its extension direction, wherein the thickness of the partition 4 is 1.9 mm to 2.1 mm. In the present embodiment, the thickness of the partition 4 is 2 mm, and the inner diameter of the first heat exchange channel is 19 mm.

[0054] The partition 4 evenly separates the first heat exchange channel into the first flow channel 2 and the second flow channel 3 along its extension direction, ensuring that the two cooling media, water and oil, circulate independently in their respective flow channels, avoiding cross contamination between the two media and maintaining the purity and cooling characteristics of the media.

[0055] The thickness of the partition 4 is designed to be 2mm, which can ensure the space of the flow channel without causing significant flow resistance. The inner diameter of the first heat exchange channel is 19mm, and combined with the size of the partition 4, two semicircular flow channels with a radius of 9.5mm are formed. This design makes the fluid flow smoother and improves the heat exchange efficiency.

[0056] By precisely separating the flow channels, the flow path and contact area of ​​each medium in the flow channel are optimized, ensuring full contact and effective heat exchange between the medium and the refrigerant in the second heat exchange channel, thereby improving the cooling effect and energy utilization.

[0057] The arrangement of the partition 4 enables the cooling structure to cool both water and oil at the same time, which meets the different requirements of different components in the machine tool for cooling medium. For example, components that need lubrication, such as the spindle, are suitable for oil cooling, while components that do not need lubrication, such as the lead screw, are suitable for water cooling. This flexibility of the cooling structure enhances its wide applicability in industrial applications.

[0058] The arrangement of the partition 4 and the independence of the flow channels enable each flow channel to be handled individually during maintenance and cleaning without affecting the medium in another flow channel, thereby reducing maintenance costs and time and improving the operating efficiency of the system.

[0059] Furthermore, the cooling structure further comprises: a first delivery pipeline, the first delivery pipeline is in communication with the first flow channel 2, and one end of the first delivery pipeline away from the first flow channel 2 is connected to the component to be cooled;

[0060] The second delivery pipeline is communicated with the second flow channel 3, and one end of the second delivery pipeline away from the second flow channel 3 is connected to the component to be cooled, so as to deliver the cooling medium to the component to be cooled through the first delivery pipeline and the second delivery pipeline.

[0061] Specifically, the cooling structure also includes a first delivery pipe connected to the first flow channel 2, the other end of the first delivery pipe is connected to the component to be cooled, so as to deliver the cooling medium to the component to be cooled through the first delivery pipe, and also includes a second delivery pipe connected to the second flow channel 3, the other end of the second delivery pipe is connected to the component to be cooled, and another cooling medium is delivered to the component to be cooled through the second delivery pipe.

[0062] The first delivery pipeline and the second delivery pipeline ensure that the two cooling media, water and oil, can enter the component to be cooled independently, thereby avoiding mixing and interference during the delivery process.

[0063] Since water and oil are transported through independent pipelines, the temperatures of the two media can be independently controlled to achieve separate control of the cooling temperatures of the first detection area and the second detection area on the component to be cooled.

[0064] Independent delivery pipelines reduce heat loss of the medium during transportation, because the pipeline can be directly optimized according to the characteristics of the medium, such as the use of insulation materials and the improvement of the smoothness of the inner wall of the pipeline, thereby ensuring that the cooling medium still maintains a high cooling capacity when it reaches the components to be cooled.

[0065] Independent delivery pipelines reduce the impact of single failure points in the system. Even if one pipeline fails, the other pipeline can continue to work, ensuring that the cooling function is not affected during cooling, thereby improving the overall operational stability and reliability.

[0066] Since the water and oil pipelines are independent, maintenance can be performed on different pipelines, such as cleaning and leak inspection, without interfering with the flow of other media. This design also facilitates the diagnosis and repair of system failures, reducing maintenance costs and downtime.

[0067] Furthermore, the component to be cooled includes a first detection area, and a first temperature detection component is provided on the first detection area to detect a first real-time temperature of the first detection area;

[0068] The cooling structure also includes: a first flow regulating valve, which is arranged on the first delivery pipeline and connected to the first temperature detection component to control the flow of the cooling medium entering the component to be cooled from the first flow channel 2 according to the detection result of the first temperature detection component.

[0069] Furthermore, the component to be cooled also includes a second detection area, and a second temperature detection component is provided on the second detection area to detect a second real-time temperature of the second detection area;

[0070] The cooling structure also includes: a second flow regulating valve, which is arranged on the second delivery pipeline and connected to the second temperature detection component to control the flow of the cooling medium entering the component to be cooled from the second flow channel 3 according to the detection result of the second temperature detection component.

[0071] Specifically, the component to be cooled includes a first detection area and a second detection area. A first temperature detection component is provided on the first detection area to detect a first real-time temperature of the first detection area. A first flow regulating valve is provided on the first delivery pipeline, and the first flow regulating valve is connected to the first temperature detection component to control the flow of the cooling medium entering from the first flow channel 2 to the component to be cooled according to the detection result of the first temperature detection component. A second temperature detection component is provided on the second detection area to detect a second real-time temperature of the second detection area. A second flow regulating valve is provided on the second delivery pipeline, and the second flow regulating valve is connected to the second temperature detection component to control the flow of the cooling medium entering from the second flow channel 3 to the component to be cooled according to the detection result of the second temperature detection component.

[0072] The first temperature detection component and the second temperature detection component can monitor the temperature change of a specific area of ​​the component to be cooled in real time, so as to respond quickly to the temperature change and adjust the flow rate of the cooling medium in time to achieve the best cooling effect and temperature stability.

[0073] The first flow regulating valve and the second flow regulating valve adjust the flow of the cooling medium entering the component to be cooled according to the feedback of the corresponding temperature detection component. When the temperature of a certain area rises, the corresponding flow regulating valve will increase the supply of cooling medium, and vice versa, it will reduce the supply, thus realizing dynamic optimization of the flow.

[0074] This design allows independent thermal management of different components or different areas of a component, which means that personalized cooling strategies can be provided according to the actual heat load requirements of each area, avoiding over-cooling or under-cooling, thereby improving processing accuracy and equipment efficiency.

[0075] By precisely controlling the flow rate, unnecessary cooling medium circulation is avoided, cooling medium loss is reduced, and energy utilization is improved.

[0076] Independent temperature detection and flow regulation functions enable the cooling system to adapt to temperature changes in different working environments and conditions. Whether it is high-load or low-load processing, the system can automatically adjust to maintain the optimal state of cooling medium flow, enhancing the adaptability and flexibility of the system.

[0077] Furthermore, the cooling structure further comprises: a flow detection component, the flow detection component is arranged on the first delivery pipeline and / or the second delivery pipeline, and the detection end of the flow detection component faces the first delivery pipeline and / or the second delivery pipeline to detect the real-time flow of the cooling medium in the first delivery pipeline and / or the second delivery pipeline;

[0078] The display component is connected with the flow detection component to display the real-time flow.

[0079] Specifically, the cooling structure also includes a flow detection component arranged on the first delivery pipe and / or the second delivery pipe, the detection end of the flow detection component is facing the first delivery pipe and / or the second delivery pipe to detect the real-time flow of different cooling media in the first delivery pipe and / or the second delivery pipe, and also includes a display component connected to the flow detection component to display the real-time flow.

[0080] The flow detection component can monitor the flow of the cooling medium in the first delivery pipeline and the second delivery pipeline in real time to ensure that the supply of the cooling medium matches the actual demand of the component to be cooled.

[0081] The setting of the display component enables the operator to intuitively see the real-time flow of the cooling medium, so that the staff can monitor the cooling process in real time and adjust the relevant parameters of the cooling.

[0082] By precisely controlling the flow of the cooling medium, unnecessary medium circulation is avoided, the energy consumption of the system is reduced, and the waste of cooling medium is reduced, thereby achieving energy savings and reducing operating costs.

[0083] Further, the cross-sectional areas of the first flow channel 2 and the second flow channel 3 are equal; and / or,

[0084] The cross-sectional shapes of the first flow channel 2 and the second flow channel 3 are semicircular.

[0085] Specifically, ensuring that the cross-sectional areas of the first flow channel 2 and the second flow channel 3 are equal can avoid the problem of uneven flow caused by differences in flow channel sizes, making the flow distribution of the two cooling media, water and oil, in the system more balanced, thereby ensuring the consistency and stability of the cooling effect.

[0086] The semicircular cross-sectional shape is adopted. Compared with the traditional circular or other shaped pipes, the semicircular flow channel can provide a longer fluid contact path in a limited space, thereby increasing the heat exchange area and improving the cooling efficiency. At the same time, the special shape of the semicircular flow channel is conducive to reducing the turbulence of the fluid, ensuring the smoothness of the medium flow and the stability of the system operation.

[0087] The semicircular flow channel design not only optimizes the heat exchange performance, but also improves the space utilization of the cooling structure.

[0088] The design of flow channels with equal cross-sectional areas and consistent shapes further enhances the separation effect of water and oil, avoids the risk of cooling medium mixing due to mismatched flow channel shapes or sizes, and ensures the reliability of the cooling effect and the purity of the cooling medium.

[0089] Further, the cooling assembly includes: a cooling pipe 5, the inlet end of the cooling pipe 5 is connected to the outlet end of the second heat exchange channel, and the outlet end of the cooling pipe 5 is connected to the inlet end of the second heat exchange channel;

[0090] Along the flow direction of the refrigerant in the second heat exchange channel, a compressor 6 and a condenser 8 are sequentially arranged on the cooling pipe 5 to exchange heat with the heat source entering the first heat exchange channel;

[0091] The electronic expansion valve 9 is disposed between the condenser 8 and the heat exchanger 1 to control the flow of the refrigerant entering the second heat exchange channel of the heat exchanger 1 .

[0092] Specifically, the cooling component includes a cooling pipe 5, the inlet end of the cooling pipe 5 is connected to the outlet end of the second heat exchange channel, and the outlet end of the cooling pipe 5 is connected to the inlet end of the second heat exchange channel. Along the flow direction of the refrigerant in the second heat exchange channel, a compressor 6 and a condenser 8 are sequentially arranged on the cooling pipe 5, and an electronic expansion valve 9 is also provided between the condenser 8 and the heat exchanger 1, so as to control the flow of the refrigerant entering the second heat exchange channel.

[0093] Specifically, the inlet end of the cooling pipe is connected to the outlet end of the second heat exchange channel, and the outlet end is connected to the inlet end of the second heat exchange channel, forming a closed refrigerant circulation path. This design ensures the circulation efficiency of the refrigerant, allowing the refrigerant to continuously absorb and release heat, achieving an efficient cooling effect.

[0094] The compressor 6 is arranged on the cooling pipe, which can compress the refrigerant from a low temperature and low pressure state to a high temperature and high pressure state, thereby releasing heat in the condenser 8 and condensing into liquid refrigerant. Under the action of the electronic expansion valve 9, the liquid refrigerant is decompressed and cooled, and enters the second heat exchange channel again to absorb heat from the oil or water, effectively improving the heat exchange efficiency.

[0095] The electronic expansion valve 9 is located between the condenser 8 and the heat exchanger 1, and can adjust the flow of the refrigerant in real time according to the cooling demand. This precise flow control is essential to maintain the system running at high efficiency and low energy consumption, especially in situations where rapid response to temperature changes is required, and the cooling intensity can be adjusted in time to avoid overcooling or insufficient cooling.

[0096] Further, the partition plate 4 is fixedly connected to the first heat exchange channel; and / or,

[0097] The partition plate 4 is integrally formed with the first heat exchange channel.

[0098] The partition plate 4 and the first heat exchange channel are fixedly connected or integrally formed, thereby enhancing the structural stability of the entire heat exchanger 1. The integral forming method, especially in the double-channel sleeve type (the first heat exchange channel and the second heat exchange channel in this application adopt the double-channel sleeve type), can reduce the joints and connection points between components and reduce the risk of structural deformation or leakage caused by long-term thermal expansion and contraction.

[0099] The close connection between the partition plate 4 and the first heat exchange channel ensures that the two media, water and oil, flow independently in their respective channels, avoiding direct contact and mixing between the media. This design optimizes the heat exchange path, increases the heat exchange area, and thus improves the heat exchange efficiency, allowing the cooler to more effectively control the temperature of the components.

[0100] If the partition plate 4 and the first heat exchange channel are formed in one piece, the manufacturing process can be greatly simplified, the assembly steps can be reduced, the production cost and potential manufacturing errors can be reduced. The one-piece molding can also ensure the sealing between the partition plate 4 and the heat exchange channel, and improve the production quality and consistency of the finished product.

[0101] Fixed connection or one-piece bulkhead design reduces the number of parts that need to be disassembled and reassembled during maintenance, simplifies the maintenance process, and reduces maintenance costs and time. In addition, the one-piece design reduces maintenance problems caused by improper connection or aging, and improves the long-term reliability of the equipment.

[0102] The fixed connection or integral molding of the partition 4 ensures the thermal isolation effect between the two flow channels, so that the electronic expansion valve 9 can more accurately control the refrigerant flow entering each flow channel, thereby improving the control accuracy of the cooling medium temperature, ensuring the temperature stability of the machine tool components during the processing, and improving the processing accuracy and equipment performance.
