Abstract
Description
Technical Field
[0001] The present application relates to but is not limited to the field of heat exchange technology, and in particular to a heat exchange component with a multi-channel heat exchange structure, and equipment with heat exchange requirements. Background Art
[0002] At present, a large number of equipment, such as gas turbine engines, electronic equipment, power batteries, energy storage batteries and other equipment, have heat exchange components. For example, the temperature of the turbine blades of a gas turbine engine is high during use and needs to be dissipated. Electronic equipment, power batteries, energy storage batteries and other equipment will generate a lot of heat during operation, causing the temperature of the equipment to rise. It is necessary to reduce the temperature of the components through heat exchange structures to improve equipment performance and enhance equipment safety. How to improve the heat exchange capacity of heat exchange components is an urgent problem to be solved. Utility Model Content
[0003] The present application provides a multi-channel heat exchange structure, a heat exchange component and a device with heat exchange requirements, which can improve the heat exchange capacity of the heat exchange component.
[0004] To this end, an embodiment of the present application provides a multi-channel heat exchange structure, which is provided with a heat exchange channel; the heat exchange channel includes a plurality of folding impact channels arranged side by side and independent of each other, an inlet and an outlet are respectively provided at both ends of the folding impact channel, the folding impact channel includes at least one folding section and at least one impact section connected to the inlet and the outlet, the folding section is inclined relative to the normal of the inlet and inclined relative to the impact section; along the extension direction of the folding impact channel, the folding sections and the impact sections are alternately arranged in sequence and connected to each other.
[0005] During use, the heat exchange medium enters the turning impact channel from the inlet and flows out of the turning impact channel from the outlet. During the flow process, it enters the turning section to turn and then injects into the impact section to form an impact jet, and takes away the heat absorbed by the multi-channel heat exchange structure to achieve the heat dissipation function. The inclined turning section can guide the heat exchange medium to impact the heat exchange surface of the multi-channel heat exchange structure, thereby thinning the boundary layer, increasing the turbulent density of the heat exchange medium, and thus improving the heat exchange intensity. The formation of an impact jet through the impact section can enhance the transfer of heat and momentum, and is also conducive to improving the heat exchange efficiency.
[0006] In addition, multiple folding shock channels are arranged side by side, which is beneficial to expanding the heat exchange range; and multiple folding shock channels are independent of each other, which is beneficial to increasing the flow rate of the heat exchange medium, thereby improving the heat exchange efficiency. By increasing the number of folding shock channels, the folding shock channels can be expanded in the combination direction (i.e., the direction perpendicular to the flow direction of the heat exchange medium, which is also the arrangement direction of the multiple folding shock channels) to expand the heat exchange range of the multi-channel heat exchange structure. The heat exchange range of the multi-channel heat exchange structure can also be expanded by increasing the number of folding sections and shock sections included in the folding shock channels and expanding in the flow direction of the heat exchange medium (i.e., the extension direction of the folding shock channels).
[0007] In addition, the multi-channel heat exchange structure mainly meets the heat exchange needs of the heat exchange area by expanding in the flow direction and expanding in the direction of the combined folded impact channels. It is suitable for being set as a flat structure and is suitable for equipment with relatively flat heat exchange areas, such as gas turbine engine turbine blades, electronic equipment, power batteries, energy storage batteries, and other equipment that have high requirements for the compactness of the heat exchange structure.
[0008] An embodiment of the present application also provides a heat exchange component, comprising a multi-channel heat exchange structure as described in any one of the above embodiments.
[0009] An embodiment of the present application also provides a device with heat exchange requirements, including the heat exchange component as described in the above embodiment.

DETAILED DESCRIPTION
[0029] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.
[0030] like Figures 1 to 3 As shown, the embodiment of the present application provides a multi-channel heat exchange structure 1. The multi-channel heat exchange structure 1 can be used to achieve a heat dissipation function or a heat preservation function, depending on the heat exchange requirements of the device. The following takes the multi-channel heat exchange structure 1 used to achieve the heat dissipation function as an example for explanation.
[0031] The multi-channel heat exchange structure 1 is provided with heat exchange channels 3. Figures 7 to 9 , Figures 13 to 15 As shown, the heat exchange channel 3 includes a plurality of folding shock channels 6 which are arranged side by side and are independent of each other. An inlet and an outlet (collectively referred to as the heat exchange medium inlet and outlet 5) are respectively provided at both ends of the folding shock channel 6. The inlet is for the heat exchange medium to enter the folding shock channel 6, and the outlet is for the heat exchange medium to flow out of the folding shock channel. The heat exchange medium may be, but is not limited to: a gaseous heat exchange medium (such as air), a liquid heat exchange medium (such as water, oil, etc.). Furthermore, since the folding shock channels 6 are independent of each other, the heat exchange medium in different folding shock channels 6 may be the same or different.
[0032] like Figures 4 to 6 , Figures 10 to 12 As shown, the turning impact channel 6 includes at least one turning segment 9 and at least one impact segment 10 connected to the inlet and the outlet. The turning segment 9 is arranged obliquely relative to the normal line of the inlet and is arranged obliquely relative to the impact segment 10. Along the extension direction of the turning impact channel 6, the turning segments 9 and the impact segments 10 are arranged alternately in sequence and are connected to each other.
[0033] During use, the heat exchange medium enters the folded impact channel 6 from the inlet and flows out of the folded impact channel 6 from the outlet. During the flow, it enters the folding section 9 to bend, and then enters the impact section 10 to form an impact jet, and takes away the heat absorbed by the multi-channel heat exchange structure 1 to achieve the heat dissipation function. The inclined folding section 9 can guide the heat exchange medium to impact the heat exchange surface 4 of the multi-channel heat exchange structure 1, thereby thinning the boundary layer, increasing the turbulent density of the heat exchange medium, and thus improving the heat exchange intensity. The impact jet formed by the impact section 10 can enhance the transfer of heat and momentum, and is also conducive to improving the heat exchange efficiency.
[0034] In addition, multiple folding shock channels 6 are arranged side by side, which is beneficial to expanding the heat exchange range; and multiple folding shock channels 6 are independent of each other, which is beneficial to increasing the flow rate of the heat exchange medium, thereby improving the heat exchange efficiency. By increasing the number of folding shock channels 6, the folding shock channels 6 can be expanded in the combination direction (i.e., the direction perpendicular to the flow direction of the heat exchange medium, which is also the arrangement direction of the multiple folding shock channels 6) to expand the heat exchange range of the multi-channel heat exchange structure 1. The heat exchange range of the multi-channel heat exchange structure 1 can also be expanded by increasing the number of folding sections 9 and shock sections 10 included in the folding shock channel 6 and expanding in the flow direction of the heat exchange medium (i.e., the extension direction of the folding shock channel 6).
[0035] In addition, the multi-channel heat exchange structure 1 mainly meets the heat exchange requirements of the heat exchange area by expanding in the flow direction and expanding in the combined direction of the folded impact channel 6. It is suitable for being set as a flat structure and is suitable for equipment with relatively flat heat exchange areas, such as turbine blades of gas turbine engines, electronic equipment, power batteries, energy storage batteries, and other equipment that have high requirements for the compactness of the heat exchange structure.
[0036] The flow directions of the heat exchange medium in different turning impact channels 6 can be the same or opposite. The turning section 9 and the impact section 10 can form an acute angle, a right angle, or an obtuse angle. The inclination angle of the turning section 9 relative to the impact section 10 (which can be recorded as the turning angle α or the inclination angle) is greater than 0°, such as Fig.16 shown.
[0037] In some exemplary embodiments, Figures 4 to 6 , Figures 10 to 12 As shown, the turning impact channel 6 also includes two inlet and outlet sections 8. The two inlet and outlet sections 8 are respectively located at the two ends of the turning impact channel 6, and the inlet and outlet sections 8 are arranged adjacent to the turning section 9. The inlet is arranged at one of the two inlet and outlet sections 8, and the outlet is arranged at the other of the two inlet and outlet sections 8.
[0038] The length of the inlet and outlet sections 8 can be adjusted as needed. The length and inclination of the turning section 9 can be adjusted as needed. The length of the impact section 10 can be adjusted as needed.
[0039] In some embodiments, Figure 7 and Fig.13 As shown, along the arrangement direction of the multiple turning impact channels 6, the adjacent inlet and outlet sections 8 are arranged flush. In this way, the multi-channel heat exchange structure 1 is relatively regular and easy to process and shape.
[0040] In some embodiments, Figures 4 to 6 , Figures 10 to 12As shown, the extension direction of the impact section 10 is consistent with the extension direction of the inlet and outlet sections 8. In this way, the multi-channel heat exchange structure 1 is relatively regular and easy to process and shape.
[0041] In some exemplary embodiments, along the arrangement direction of the multiple turning impact channels 6, the inclination directions of adjacent turning segments 9 relative to the normal of the inlet are opposite. In this way, along the arrangement direction of the multiple turning impact channels 6, the adjacent impact segments 10 are staggered, and can be close to different structures to be heat exchanged, which is equivalent to realizing the heat exchange function of two heat exchange surfaces 4 at the same time, and is more suitable for arrangement on equipment with a compact heat exchange area.
[0042] In some exemplary embodiments, the folding impact channel 6 includes a plurality of folding segments 9 and a plurality of impact segments 10. Through the extension of the plurality of folding segments 9 and the plurality of impact segments 10 along the flow direction, the heat exchange medium can be continuously folded in the folding impact channel 6 and continuously form impact jets in the impact segments 10, thereby enhancing the heat exchange capacity.
[0043] Along the extension direction of the folded impact channel 6, the inclination directions of adjacent folded segments 9 relative to the normal of the inlet are opposite. In this way, along the extension direction of the folded impact channel 6, adjacent impact segments 10 are staggered and can be close to different structures to be heat exchanged, which is equivalent to realizing the heat exchange function of two heat exchange surfaces 4 at the same time, and is more suitable for arrangement on equipment with a compact heat exchange area.
[0044] In some exemplary embodiments, the multi-channel heat exchange structure 1 is flat. Figure 7 and Fig.13 As shown, all the impact sections 10 of the heat exchange channel 3 are divided into two impact section 10 groups along the thickness direction of the multi-channel heat exchange structure 1, and each impact section 10 group includes a plurality of impact sections 10 arranged at intervals and flush with each other. In this way, the multi-channel heat exchange structure 1 can realize the heat exchange function of two heat exchange surfaces 4 at the same time, and is more suitable for being arranged on equipment with a compact heat exchange area. In addition, the multi-channel heat exchange structure 1 is relatively regular and easy to process and shape.
[0045] In some exemplary embodiments, Figures 4 to 9 As shown, the impact section 10 is an expansion impact section 11. Along the extension direction of the turning impact channel 6, the cross-sectional area of the expansion impact section 11 is larger than the cross-sectional area of the turning section 9.
[0046] This is beneficial to increase the heat exchange surface area and flow rate of the impact section 10, thereby improving the heat exchange efficiency. In addition, the expansion type impact section 10 increases the pressure gradient in the direction perpendicular to the flow direction and the combination direction (i.e., the thickness direction of the multi-channel heat exchange structure 1), thereby thinning the fluid boundary layer and enhancing the heat exchange performance. The expansion degree of the expansion impact section 11 can be adjusted as needed.
[0047] Furthermore, along the arrangement direction of the multiple folded impact channels 6, adjacent impact segments 10 of each impact segment 10 group can be close to each other or even close together, which is beneficial to increase the heat exchange surface area 4 of each impact segment 10 group, thereby improving the heat exchange efficiency.
[0048] In some embodiments, Figures 4 to 9 As shown, along the extension direction of the folded impact channel 6, the cross-sectional area of the expansion impact section 11 increases first and then decreases.
[0049] In some embodiments, along the arrangement direction of the multiple deflection impact channels 6, the cross-sectional area of the expansion impact section 11 increases first and then decreases, such as Figures 4 to 9 shown.
[0050] It can be that the width of the expansion shock segment 11 is greater than the width of the turning segment 9, so that the cross-sectional area of the expansion shock segment 11 is greater than the cross-sectional area of the turning segment 9. For example: along the extension direction of the turning shock channel 6, the width of the expansion shock segment 11 first increases and then decreases. Along the arrangement direction of the multiple turning shock channels 6, the length of the expansion shock segment 11 first increases and then decreases. Among them, the width of the expansion shock segment 11 is consistent with the arrangement direction (or combination direction) of the multiple turning shock channels 6. The length of the expansion shock segment 11 is consistent with the flow direction of the heat exchange medium inside it.
[0051] In some embodiments, Figure 5 As shown, the expansion impact section 11 includes a gradually expanding section 13, a uniform cross-section section 14 and a gradually contracting section 15 which are connected in sequence. Along the extension direction of the turning impact channel 6, the cross-sectional area of the gradually expanding section 13 gradually increases, the cross-sectional area of the uniform cross-sectional section 14 remains unchanged, and the cross-sectional area of the gradually contracting section 15 gradually decreases.
[0052] In this way, along the extension direction of the folded impact channel 6, the cross-sectional area of the expansion impact section 11 increases first and then decreases.
[0053] In some embodiments, Figures 4 to 9 As shown, the gradually expanding section 13 and the gradually contracting section 15 are symmetrically arranged on both sides of the equal cross-section section 14. In this way, the multi-channel heat exchange structure 1 is relatively regular and convenient for processing and forming.
[0054] In some embodiments, Figures 4 to 9 As shown, the expansion impact section 11 is a mirror-symmetrical structure, and is mirror-symmetrical about a symmetry plane perpendicular to the arrangement direction of the multiple folding impact channels 6. In this way, the multi-channel heat exchange structure 1 is relatively regular and easy to process and shape. In addition, along the arrangement direction of the multiple folding impact channels 6, the cross-sectional area of the expansion impact section 11 can first increase and then decrease.
[0055] In one example, if Figure 5 As shown, the projections of the gradually expanding section 13 and the gradually contracting section 15 on the plane perpendicular to the above-mentioned symmetry plane are isosceles trapezoids.
[0056] In other exemplary embodiments, Figures 10 to 15 As shown, the impact section 10 is a uniform cross-section impact section 12. Along the extension direction of the folded impact channel 6, the cross-sectional area of the uniform cross-sectional impact section 12 remains unchanged and is equal to the cross-sectional area of the folded section 9. In this way, the multi-channel heat exchange structure 1 is relatively regular and easy to process and shape.
[0057] In some exemplary embodiments, Figures 1 to 3 As shown, the multi-channel heat exchange structure 1 includes a heat-conducting matrix 2. The heat exchange channel 3 is arranged in the heat-conducting matrix 2, and the heat-conducting matrix 2 has two heat exchange surfaces 4 arranged opposite to each other. In this way, the outer surface of the multi-channel heat exchange structure 1 is relatively flat, which is convenient for contacting and fitting with the heat exchange component.
[0058] The heat-conducting substrate 2 can be configured as a plate-like structure, and the heat exchange channel 3 is arranged in the plate-like structure. The two heat exchange surfaces 4 of the conductor substrate can contact with the external components to be heat exchanged to achieve heat exchange. Alternatively, the two heat exchange surfaces 4 of the heat-conducting substrate 2 can themselves exchange heat with the surrounding environment to achieve a heat dissipation effect.
[0059] The multi-channel heat exchange structure 1 can be manufactured by, but not limited to, additive manufacturing (such as 3D printing), casting and other processes, and a cavity with multiple folded impact channels 6 is formed in the heat conductive matrix 2, and the cavity is the flow space of the heat exchange medium.
[0060] In some embodiments, the two heat exchange surfaces 4 are arranged in parallel; or, an angle is formed between the two heat exchange surfaces 4. At least one heat exchange surface 4 is a plane; or, at least one heat exchange surface 4 is a curved surface.
[0061] For example, the two heat exchange surfaces 4 can be a pair of relatively parallel planes, a pair of mutually parallel curved surfaces, a pair of planes with an included angle, or a pair of curved surfaces with an included angle.
[0062] In some embodiments, the heat exchange surface 4 is a plane, and the angle between the arrangement direction of the multiple folded impact channels 6 and the normal vector of the heat exchange surface 4 can be in the range of but not limited to 20° to 160°, such as 20°, 40°, 60°, 80°, 100°, 120°, 140°, 160°, etc.
[0063] In other exemplary embodiments, the multi-channel heat exchange structure 1 includes a plurality of heat exchange tubes, each of which is provided with a folded impact channel 6. In this way, the surface of the multi-channel heat exchange structure 1 will be uneven, and it has a relatively large heat exchange surface area. The uneven areas may not be filled with heat conductive materials, or they may be filled with heat conductive materials to improve heat exchange uniformity.
[0064] The heat exchange tube can be a flat tube or a round tube. The outer walls of the multiple heat exchange tubes form a heat exchange surface 4. The heat exchange surface 4 can be in contact with the external component to be heat exchanged to achieve heat exchange, and a heat conductive material (such as heat conductive glue) can be arranged between the heat exchange surface 4 and the component to be heat exchanged to improve the heat exchange efficiency. Alternatively, the heat exchange surface 4 itself can exchange heat with the surrounding environment to achieve a heat dissipation effect.
[0065] The multi-channel heat exchange structure 1 can be composed of a thin-walled pipeline structure, and heat exchange can be performed with external heat exchange components through the outer wall of the pipeline. Heat conductive materials can also be filled between the outer wall of the pipeline and the external heat exchange components to improve heat exchange efficiency.
[0066] in, Figures 4 to 16 It may be a physical representation in which the heat exchange channel 3 is separated from the heat conductive base 2, or it may be a multi-channel heat exchange structure 1 formed by a plurality of heat exchange tubes.

[0068] In some embodiments, the heat exchange component may be, but is not limited to: a blade (such as a turbine blade of a gas turbine engine), a radiator (such as a radiator of an electronic device, a radiator of a battery).
[0069] The multi-channel heat exchange structure 1 may be a part of a heat exchange component, and may be integrally formed with other parts of the heat exchange component or may be separately formed.
[0070] The embodiment of the present application also provides a device with heat exchange requirements, including a heat exchange component as in the above embodiment, and thus has all the above beneficial effects, which are not described in detail in this step.

[0073] In some embodiments, the device is an electronic device. For example, the electronic device may be a circuit board, and the multi-channel heat exchange structure 1 may be a radiator, which is attached and fixed to the board body of the circuit board to dissipate heat for the entire circuit board; or it may be attached and fixed to electronic components on the circuit board that generate a large amount of heat to dissipate heat for electronic components that generate a large amount of heat. The heat exchange medium may be a coolant.

The battery can include multiple battery cells, and the multi-channel heat exchange structure 1 can be a radiator, which is sandwiched between adjacent battery cells and is attached and fixed to adjacent battery cells to dissipate heat from adjacent battery cells. The heat exchange medium can be a coolant.
