[0002] Aging test equipment is an important piece of equipment in the production process of electronic products (such as Bluetooth headsets, smart bracelets, etc.). It is used to test the aging life of electronic products. During the operation of aging test equipment, local high temperature problems may occur.

[0003] Currently, due to the limited installation space inside the aging test equipment, fans are mainly installed at both ends of the equipment to cool the whole machine. However, it is impossible to provide directional heat dissipation to high-temperature areas, making it difficult to reduce the temperature at these locations. This results in poor heat dissipation and seriously affects the accuracy of the test structure. Utility Model Content

[0004] The purpose of this invention is to provide a directional heat dissipation structure and an integrated heat dissipation device, which aims to solve the problems of existing heat dissipation equipment being unable to achieve directional heat dissipation and having poor heat dissipation effect.

[0005] This utility model discloses a directional heat dissipation structure, which includes a plate and at least two heat dissipation grooves arranged side by side on the side of the plate. Each heat dissipation groove forms a heat dissipation channel. Multiple air blowing holes are provided on the bottom surface of the heat dissipation groove. The structure also includes an air inlet provided on the plate, which is connected to the air blowing holes.

[0006] As an improvement, the plate is provided with an air guiding structure, and the air inlet and the air blowing hole are respectively connected to the air guiding structure.

[0007] As an improvement, the air guiding structure includes a first air passage provided for each of the heat dissipation slots, and a plurality of air blowing holes on the bottom of the heat dissipation slots are connected to the corresponding first air passages; it also includes a second air passage connected to at least two of the first air passages.

[0008] As an improvement, the first air passage is configured as a first through hole, the second air passage is configured as a second through hole, and the directional heat dissipation structure further includes plugs for sealing the ports of the first through hole and the second through hole.

[0009] As an improvement, the air inlet is provided corresponding to the second air passage and is connected to the second air passage.

[0010] As an improvement, the port on one side of the second air passage forms the air inlet.

[0011] As an improvement, at least two second air passages are provided at intervals, each second air passage is connected to at least two first air passages, and each second air passage is provided with an air inlet.

[0012] As an improvement, the air inlet is provided corresponding to the first air passage and is connected to the first air passage.

[0013] As an improvement, the port on one side of the first airway forms the air inlet.

[0014] As an improvement, the ports of the first through hole and the second through hole are respectively provided with internal threads to form threaded holes.

[0015] As an improvement, an air outlet communicating with the air guiding structure is provided on the plate.

[0016] As an improvement, the port of the first through hole or the second through hole forms the air outlet.

[0017] As an improvement, the heat dissipation groove protrudes from the side of the plate and includes spaced-apart baffles that form the heat dissipation channel between the side of the plate and between the two baffles.

[0018] This utility model also discloses an integrated heat dissipation device, which includes an air inlet pipe and at least two sets of directional heat dissipation structures. The air inlet of one set of directional heat dissipation structures is connected to the air inlet pipe, and the remaining directional heat dissipation structures are connected to the directional heat dissipation structures connected to the air inlet pipe.

[0019] Due to the adoption of the above technical solution, the directional heat dissipation structure of this utility model includes a plate body, at least two heat dissipation grooves arranged side by side on the side of the plate body, each heat dissipation groove forming a heat dissipation channel, and multiple air blowing holes provided on the bottom surface of the heat dissipation groove body. It also includes an air inlet provided on the plate body, and the air inlet is connected to the air blowing holes. The integrated heat dissipation device includes an air inlet pipe and at least two sets of directional heat dissipation structures, wherein the air inlet of one set of directional heat dissipation structures is connected to the air inlet pipe, and the remaining directional heat dissipation structures are connected to the directional heat dissipation structure connected to the air inlet pipe. In use, the directional heat dissipation structure is attached to the heat dissipation location, with the air blowing holes facing the location. The air inlet pipe is connected to the air inlet, and air is blown through the air inlet. The air is then blown out through the air blowing holes and directed towards the heat dissipation location, directly cooling the area and achieving directional heat dissipation, thus improving the heat dissipation effect. At the same time, since the air is transported from the outside to the directional heat dissipation structure through the air inlet pipe, its temperature is lower than the air around the heat dissipation location. Blowing the cooler outside air towards the heat dissipation location further enhances the heat dissipation effect. This solves the problems of existing heat dissipation equipment being unable to achieve directional heat dissipation and having poor heat dissipation effect. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Figures 1 to 4 This is a schematic diagram of the directional heat dissipation structure and integrated heat dissipation device of this utility model, wherein, Figure 1 This diagram shows a three-dimensional structural schematic of the directional heat dissipation structure of this utility model. Figure 2 An exploded view of the directional heat dissipation structure of this invention is shown. Figure 3 A cross-sectional view of the directional heat dissipation structure of this utility model is shown. Figure 4 A three-dimensional structural schematic diagram of the integrated heat dissipation device of this utility model is shown. For ease of description, only the parts relevant to this utility model are shown in the figure.

[0027] It should be noted that if the directional indications (such as up, down, front, back, etc.) involved in this utility model are only used to explain the relative positional relationship between the components in a certain specific posture, the directional indications will change accordingly if the specific posture changes; if the descriptions of "first", "second", etc. involved in this utility model are used for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0028] Depend on Figure 1 , Figure 2 and Figure 3It is understood that the directional heat dissipation structure of this utility model includes a plate 10, at least two heat dissipation grooves arranged side by side on the side of the plate 10, each heat dissipation groove forming a heat dissipation channel, a plurality of air blowing holes 20 provided on the bottom surface of the heat dissipation groove, and an air inlet provided on the plate 10, which is connected to the air blowing holes 20.

[0029] In use, the directional heat dissipation structure is attached to the heat dissipation location, with the air blowing hole 20 facing the heat dissipation location. The air inlet pipe 60 is connected to the air inlet, and air is blown into the air inlet through the air inlet pipe 60. The air is blown out through the air blowing hole 20 and directed towards the heat dissipation location, which can directly dissipate heat from the heat dissipation location, thus achieving directional heat dissipation and improving the heat dissipation effect. At the same time, since the air is transferred from the outside to the directional heat dissipation structure through the air inlet pipe 60, its temperature is lower than the air temperature around the heat dissipation location. Blowing the cool outside air towards the heat dissipation location can further improve the heat dissipation effect. The directional heat dissipation structure of this utility model solves the problems of existing heat dissipation equipment being unable to achieve directional heat dissipation and having poor heat dissipation effect.

[0030] In this utility model, the plate 10 is provided with an air guiding structure, and the air inlet and the air blowing hole 20 are respectively connected to the air guiding structure.

[0031] like Figure 3 As shown, the air guiding structure includes a first air channel 11 corresponding to each heat sink, with each heat sink corresponding to a first air channel 11, and multiple air holes 20 on the bottom of the heat sink communicating with the corresponding first air channel 11; it also includes a second air channel 12 communicating with at least two first air channels 11.

[0032] Typically, the air inlet is connected to the second air passage 12. To improve heat dissipation, at least two second air passages 12 are provided at intervals, and each second air passage 12 is connected to at least two first air passages 11. Each second air passage 12 is provided with an air inlet, and air can be drawn in through at least two air inlets to increase the air volume. Specifically, there are two second air passages 12.

[0033] For ease of processing, the first air passage 11 is configured as a first through hole; the second air passage 12 is configured as a second through hole, with one end of the second through hole forming an air inlet; plugs 40 are respectively provided at both ends of the first through hole and the other end of the second through hole. Of course, the second air passage can also be configured as a blind hole, with the end of the blind hole forming an air inlet.

[0034] Of course, the air inlet can also be connected to the first air passage 11. Specifically, the port of the first air passage 11 forms the air inlet. In actual use, since there are multiple first air passages 11, usually two ports of the first air passages 11 are selected to connect to the air intake pipe 60.

[0035] like Figure 2 and Figure 3As shown, the ports of the first through hole and the second through hole are respectively provided with internal threads to form threaded holes; the plug 40 is a threaded plug, which is convenient for installation and disassembly. At the same time, a threaded air pipe connector 50 can also be installed to facilitate connection of the air inlet pipe 60.

[0036] In this utility model, the heat dissipation groove protrudes from the side of the plate 10 and includes spaced baffles 30, forming a heat dissipation channel between the two baffles 30 and the side of the plate 10 between the two baffles 30.

[0037] Specifically, a gap is provided between adjacent heat sinks to prevent interference between the heat dissipation channels formed by two adjacent heat sinks. Of course, the heat sinks can also be recessed into the plate 10.

[0038] In this utility model, an air outlet is provided on the plate 10, which is connected to the air inlet and the air outlet is connected to the air guiding structure.

[0039] Specifically, when the second air passage 12 is configured as the second through hole, one end of the second through hole forms an air inlet and the other end forms an air outlet. Of course, the port on one side of the first air passage 11 can also be configured as the air outlet.

[0040] In this invention, to facilitate the fixed installation of the directional heat dissipation structure at the heat dissipation location, mounting posts 70 are spaced apart on the periphery of the side of the plate 10 corresponding to the air blowing hole 20, and corresponding through mounting posts 70 and mounting holes of the plate 10 at the corresponding positions are provided. Correspondingly, threaded holes are provided at the heat dissipation location, and during installation, bolts are connected by passing them through the mounting holes and threaded holes.

[0041] In some other embodiments, the plate 10 has an air cavity inside, and the air inlet, the blowing hole 20 and the air outlet are respectively connected to the air cavity.

[0042] Depend on Figure 4 It is understood that this utility model also discloses an integrated heat dissipation device, including an air inlet pipe 60 and at least two sets of the aforementioned directional heat dissipation structures. The air inlet of one set of directional heat dissipation structures is connected to the air inlet pipe 60, and the remaining directional heat dissipation structures are connected to the directional heat dissipation structures connected to the air inlet pipe 60. In use, different directional heat dissipation structures can be placed at different heat dissipation locations, enabling simultaneous heat dissipation at different locations.

[0043] Specifically, a set of directional heat dissipation structures connected to the intake pipe 60 forms the initial heat dissipation structure; the remaining directional heat dissipation structures include at least two sets of directional heat dissipation structures connected to the initial heat dissipation structure, forming the intermediate heat dissipation structure, and at least one set of directional heat dissipation structures connected to the intermediate heat dissipation structure, forming the final heat dissipation structure, such as... Figure 4As shown, the middle heat dissipation structure has two sets of directional heat dissipation structures, and the end heat dissipation structure has one set of directional heat dissipation structures. The initial, middle, and end heat dissipation structures can be used for heat dissipation at different locations.
