Description

Technical Field

[0001] This invention belongs to the technical field of dispensing devices, and particularly relates to a heat pipe heat exchanger suitable for glue valves. Background Technology

[0002] The dispensing states of glue valves are commonly divided into two types: horizontal dispensing state and vertical dispensing state. When the glue valve is working, the motor inside the valve body generates heat, so it is often necessary to cool down the glue valve to ensure its normal operation.

[0003] Currently, conventional finned radiators or heat pipe radiators are commonly used in the market to dissipate heat from the glue valve. However, conventional finned radiators are greatly affected by airflow. If the airflow around the finned radiator is slow or obstructed, the heat dissipation efficiency will be reduced. If a heat pipe radiator is used, changing the glue valve between horizontal and vertical dispensing states will change the relative positions of the evaporator and condenser ends in the heat pipe radiator, making it difficult for the condensate to flow back and weakening the heat transfer effect.

[0004] Based on the above, there is an urgent need for a heat pipe heat exchanger suitable for rubber valves to solve the technical problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a heat pipe heat exchanger suitable for glue valves, which can meet the heat dissipation requirements of glue valves in both horizontal and vertical dispensing conditions, and ensure the high-efficiency heat dissipation of the heat pipe heat exchanger.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Heat pipe heat exchangers suitable for rubber valves include:

[0008] The heat dissipation fins have a vertically arranged heat dissipation main surface, and the glue valve is provided on the side end of the heat dissipation main surface;

[0009] Several heat pipes are obliquely fixed on the heat dissipation main surface. Each heat pipe includes an evaporation end and a condensation end. The heat pipes are configured such that when the glue valve is in a horizontal dispensing state and a vertical dispensing state, the horizontal height of the condensation end of the heat pipe is higher than the horizontal height of the evaporation end of the heat pipe.

[0010] Optionally, at least two of the heat pipes may be included.

[0011] Optionally, the heat pipe includes at least one of U-shaped heat pipe, S-shaped heat pipe, V-shaped heat pipe, and M-shaped heat pipe.

[0012] Optionally, the heat pipe is a U-shaped heat pipe.

[0013] Optionally, the cross-section of the heat dissipation fins is polygonal along a direction perpendicular to the heat dissipation main surface.

[0014] Optionally, multiple heat pipes are arranged at intervals along a direction perpendicular to the inclined arrangement of the heat pipes, and on the same heat pipe, the projection distance between the evaporation end and the condensation end on the heat dissipation main surface gradually increases in the direction pointing towards the center of the heat dissipation main surface.

[0015] Optionally, the heat dissipation fins have notches along a direction perpendicular to the heat dissipation main surface to reduce the cross-sectional area of ​​the heat dissipation main surface.

[0016] Optionally, along a direction perpendicular to the heat dissipation main surface, the heat pipe heat exchanger includes a plurality of heat dissipation fins, the glue valve is located on the same side end of the plurality of heat dissipation fins, and the evaporation end and the condensation end are both inserted through the plurality of heat dissipation fins.

[0017] Optionally, it also includes an assembly part, which includes a first end face and a second end face disposed opposite to each other, the first end face being fixedly connected to the same side end of the plurality of heat dissipation fins, and the second end face being configured to fix the glue valve.

[0018] Optionally, a thermally conductive adhesive layer is sandwiched between the second end face and the adhesive valve.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a heat pipe heat exchanger suitable for a glue valve. The heat pipe heat exchanger includes heat dissipation fins and a plurality of heat pipes. The heat dissipation fins have a main heat dissipation surface, and the glue valve is located at the side end of the main heat dissipation surface. By tilting the heat pipes onto the main heat dissipation surface, the horizontal height of the condensing end on the heat pipe is higher than that of the evaporating end on the heat pipe, regardless of whether the glue valve is in a horizontal or vertical glue dissipation state. This ensures the smooth flow of condensate back and also ensures that the high-temperature gas formed after the condensate evaporates can be quickly transported upward to the condensing end, preventing the accumulation of high-temperature gas. Thus, the heat pipe heat exchanger achieves the purpose of high-efficiency heat dissipation. Attached Figure Description

[0033] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0036] The following is combined with Figures 1 to 9 The present invention provides a heat pipe heat exchanger suitable for rubber valves, and specific embodiments are described in this paper.

[0037] Example 1

[0038] Combination Figures 1 to 3 As shown, the heat pipe heat exchanger includes heat dissipation fins 1 and several heat pipes 2. The heat dissipation fins 1 have a main heat dissipation surface 11, which is vertically arranged. A glue valve 100 is located at the bottom of the main heat dissipation surface 11. The glue valve 100 is set to spray glue to the left (e.g., ...). Figure 2 (In the direction indicated by the solid arrow); Several heat pipes 2 are obliquely fixed on the heat dissipation main surface 11. Each heat pipe 2 includes an evaporation end 21 and a condensation end 22. The evaporation end 21 is located on the left side of the bottom end of the heat dissipation main surface 11, and the condensation end 22 is located on the right side of the top end of the heat dissipation main surface 11. This allows the condensate in the heat pipe 2 to quickly flow back to the evaporation end 21 when the glue valve 100 is in the horizontal dispensing state, while the high-temperature gas-liquid in the evaporation end 21 can quickly diffuse to the condensation end 22, thereby ensuring that the heat pipe heat exchanger has a high heat dissipation efficiency at this time.

[0039] When the heat pipe heat exchanger from Figure 2 The state shown is rotated 90° counterclockwise to form as shown Figure 3 The indicated state means that the glue valve 100 has switched from horizontal dispensing to vertical dispensing, and at this time, the glue valve 100 sprays glue in a vertically downward direction (reference). Figure 3(As indicated by the dashed arrow in the middle), the distance between the evaporation end 21 of heat pipe 2 and the horizontal plane is still lower than the distance between the condensation end 22 and the horizontal plane. This ensures that when the glue valve 100 is in the vertical dispensing state, the condensate and high-temperature gas inside the heat pipe 2 can still flow rapidly, preventing accumulation. Therefore, regardless of whether the glue valve 100 is in the vertical or horizontal dispensing state, the heat pipe heat exchanger can guarantee high heat dissipation efficiency.

[0040] Understandably, the specific orientations of the evaporator end 21 and the condenser end 22 in heat pipe 2 are mainly determined by the adhesive spraying direction of the adhesive valve 100 and the installation position of the adhesive valve 100. For example, with Figure 2 As shown, when the glue valve 100 is located at the left end of the heat dissipation fin 1 and spraying glue downwards, if the glue valve 100 is set to spray glue to the left in the horizontal dispensing state, it indicates that the heat pipe heat exchanger needs to be rotated 90° clockwise. In this case, the evaporation end 21 of the heat pipe 2 is located on the right side of the bottom end of the heat dissipation main surface 11, and the condensation end 22 of the heat pipe 2 is located on the left side of the top end of the heat dissipation main surface 11. This ensures that when the glue valve 100 switches between the horizontal and vertical dispensing states, the height of the evaporation end 21 on the heat pipe 2 is always lower than the height of the condensation end 22 on the heat pipe 2. Therefore, this invention does not limit the specific orientation of the glue valve 100, the evaporation end 21, and the condensation end 22 on the heat dissipation main surface 11.

[0041] Furthermore, in this embodiment, along the direction perpendicular to the heat dissipation main surface 11, the cross-section of the heat dissipation fin 1 is polygonal, for example... Figures 1 to 5 The quadrilateral shape shown has more edges and corners than the circular heat dissipation surface 11. This helps to enhance the disturbance of the surrounding air by the heat dissipation fins 1, thereby improving the convection effect of heat exchange and making the heat dissipation effect better.

[0042] Furthermore, along the direction perpendicular to the heat dissipation main surface 11, the heat pipe heat exchanger includes multiple heat dissipation fins 1, the glue valve 100 is located at the bottom of the multiple heat dissipation fins 1, and the evaporation end 21 and the condensation end 22 of the heat pipe 2 are both inserted through the multiple heat dissipation fins 1, so as to improve the heat dissipation efficiency in the heat pipe 2 by increasing the number of heat dissipation fins 1.

[0043] Optionally, the heat pipe heat exchanger further includes an assembly part 3, which includes a first end face 31 and a second end face 32 disposed opposite to each other. The first end face 31 is fixedly connected to the bottom end of a plurality of heat dissipation fins 1. In this embodiment, the assembly part 3 and the plurality of heat dissipation fins 1 are fixedly connected by integral molding, thereby effectively enhancing the integrity and compactness of the heat pipe heat exchanger and effectively avoiding the misalignment of the heat dissipation fins 1. The glue valve 100 is fixedly disposed on the second end face 32 to enhance the connection stability and convenience of the heat pipe heat exchanger and the glue valve 100 through the flat plane.

[0044] To improve heat conduction, in this embodiment, a thermally conductive adhesive (not shown in the figure) is also applied to the second end face 32. The thermally conductive adhesive can be silicone thermally conductive adhesive, silicone thermally conductive adhesive, etc. The present invention is not limited to this. The thermally conductive adhesive layer formed after curing can effectively enhance the rate at which the adhesive valve 100 transfers heat to the heat pipe heat exchanger, thereby further improving the heat dissipation efficiency.

[0045] Optionally, in this embodiment, three heat pipes 2 are inclinedly arranged on the heat dissipation main surface 11 to meet the heat dissipation efficiency requirements under actual working conditions. Furthermore, the cross-sections of the three heat pipes 2 are all U-shaped. U-shaped heat pipes 2 have the advantages of simple construction, aesthetics, and stable structural strength, thus facilitating manufacturing and extending service life. Of course, in other embodiments, S-shaped heat pipes can also be used to achieve a longer heat transfer path within a limited space, thereby improving heat transfer efficiency; V-shaped heat pipes can also be used. Compared to U-shaped and S-shaped heat pipes, V-shaped heat pipes are the shortest, thus meeting the rate requirements for rapid return of condensate and high-temperature gas to the evaporation end 21 and condensation end 22 respectively, and also exhibiting higher structural strength; M-shaped heat pipes can also be used to adapt to complex spatial layout constraints. Therefore, those skilled in the art can determine the cross-sectional shape of the three heat pipes 2 according to the actual heat dissipation efficiency requirements and spatial layout needs. The cross-sectional shapes of the three heat pipes 2 can be the same, different from each other, or two of them can be the same. As long as it can be ensured that the horizontal height of the evaporation end 21 in one heat pipe 2 after rotating 90° is still lower than the horizontal height of the condensation end 22, they are all within the protection scope of this invention.

[0046] Further, refer to Figure 2As shown, in this embodiment, multiple heat pipes 2 are arranged at intervals along a direction perpendicular to the inclined direction of the heat pipe 2. One heat pipe 2 passes through the center of the heat dissipation main surface 11, and the projection point of the evaporation end 21 of this heat pipe 2 on the heat dissipation main surface 11 is located at the lower left corner, while the projection point of the condensation end 22 of this heat pipe 2 on the heat dissipation main surface 11 is located at the upper right corner. This maximizes the projection distance between the evaporation end 21 and the condensation end 22 of the heat pipe 2 on the heat dissipation main surface 11, while the projection distance between the evaporation end 21 and the condensation end 22 of the other heat pipes 2 on the heat dissipation main surface 11 gradually decreases. Through the above arrangement, while ensuring that the entire heat pipe heat exchanger has a relatively light weight, the space of the heat dissipation main surface 11 can be better utilized, and the heat dissipation area of ​​the heat pipe heat exchanger can be fully utilized to further improve the heat dissipation effect.

[0047] Furthermore, in this embodiment, all three heat pipes 2 are installed in the same horizontal direction within multiple heat dissipation fins 1 to facilitate manufacturing and assembly.

[0048] Example 2

[0049] This embodiment provides a heat pipe heat exchanger suitable for rubber valves. Compared with Embodiment 1, the heat pipe heat exchanger provided in this embodiment has a basically the same structure as the heat pipe heat exchanger in Embodiment 1. The only difference is that, combined with... Figure 4 , Figure 5 As shown, in this embodiment, one of the three heat pipes 2 is horizontally inserted into multiple heat dissipation fins 1 in the opposite direction to the insertion direction of the other two heat pipes 2. This allows for more flexible adaptation to different heat dissipation layouts and space constraints by changing the installation direction of one of the heat pipes 2, thereby helping to improve the overall flexibility of the heat pipe heat exchanger.

[0050] Example 3

[0051] This embodiment provides a heat pipe heat exchanger suitable for rubber valves. Compared with Embodiment 1, the structure of the heat dissipation fins 1 provided in this embodiment is different. Specifically, in conjunction with... Figure 6 , Figure 7 As shown, in this embodiment, the heat dissipation fin 1 has a notch 12 along the direction perpendicular to the heat dissipation main surface 11, thereby reducing the cross-sectional area of ​​the heat dissipation main surface 11. When the motor inside the valve 100 vibrates during operation, the heat dissipation fin 1 may resonate along the direction perpendicular to the heat dissipation main surface 11. By reducing the cross-sectional area of ​​the heat dissipation main surface 11, the structural stiffness of a single heat dissipation fin 1 can be effectively improved, enhancing its vibration resistance and deformation resistance, thereby effectively improving the stability of the heat dissipation fin 1.

[0052] Example 4

[0053] This embodiment provides a heat pipe heat exchanger suitable for rubber valves, such as... Figure 8 , Figure 9 As shown, this embodiment combines the installation method of heat pipe 2 in embodiment 2 and the feature of heat dissipation fin 1 with notch 12 in embodiment 3. In this way, while effectively ensuring the structural strength of heat dissipation fin 1, it can also enable the heat pipe heat exchanger to meet the actual design requirements of heat dissipation layout and spatial layout, thereby further enriching the applicable scenarios of the heat pipe heat exchanger.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
