[0035] Embodiment 1
[0036] According to Figures 1-4 As shown, a wearable heat dissipation device includes a heat dissipation body 100; a heat dissipation cavity 110 is provided inside the heat dissipation body 100, a heat dissipation substance is filled in the heat dissipation cavity 110, the heat dissipation substance can flow in the heat dissipation cavity 110, an installation part 120 is provided on the upper surface of the heat dissipation body 100, and the installation part 120 is used for installing the electronic product to be dissipated; and a fixing member 200; both ends of the fixing member 200 are connected to the heat dissipation body 100, and the fixing member 200 can fix the heat dissipation body 100 on various parts of the human body.
[0037] Specifically, by arranging a heat dissipation substance in the heat dissipation cavity 110, it can help the electronic product installed on the heat dissipation body 100 to dissipate heat. The heat dissipation substance can flow, which can improve the heat dissipation efficiency. By arranging the fixing member 200, the heat dissipation body 100 can be fixed on various parts of the body.
[0038] Furthermore, the heat dissipation substance can be pure water, an alcohol-water mixture, a fluorinated liquid, etc.
[0039] It can be understood that some electronic products need to be arranged on the human body for use, such as cameras, VR, AR devices, etc., and the heat dissipation body 100 needs to be fixed and adapted to different parts of the body.
[0040] It can be understood that the fixing member 200 can be of different structures such as a fixing belt, a fixing rope, a fixing ring, etc. The fixing member can be elastic or non-elastic. If it is elastic, it is sleeved on the human body part through the elastic force, such as the head, the arm part, or the waist, etc. If it is non-elastic, it is wearable, such as worn or sleeved on the neck or the wrist.
[0041] According to Figures 1-4 As shown, a flow pipe 210 is provided inside the fixing member 200. The flow pipe 210 communicates with the heat dissipation cavity 110. The heat dissipation substance can flow between the flow pipe 210 and the heat dissipation cavity 110. Two openings 130 are provided on the heat dissipation body 100. The two openings 130 communicate with the heat dissipation cavity 110. The two ends of the flow pipe 210 are respectively connected to the two openings 130 to communicate with the heat dissipation cavity 110. The opening 130 is an inlet and outlet hole. In actual design, multiple inlet holes and multiple outlet holes can also be provided.
[0042] Specifically, a flow pipe 210 is provided inside the fixing member 200. The heat dissipation substance can flow between the flow pipe 210 and the heat dissipation cavity 110, increasing the heat dissipation area, which can accelerate the dissipation of heat and increase the heat dissipation efficiency.
[0043] According to Figure 1 and 2 As shown, a micro liquid pump 300 is provided inside the flow pipe 210. The micro liquid pump 300 is used to make the heat dissipation substance in the flow pipe 210 and the heat dissipation cavity 110 flow. Specifically, without adding the micro liquid pump 300, the heat dissipation substance can slosh between the flow pipe 210 and the heat dissipation cavity 110, and the heat dissipation substance does not form a cycle. After adding the micro liquid pump 300, the heat dissipation substance flows completely. The flowing heat dissipation substance can continuously take away the heat transferred from the electronic product to the heat dissipation body, preventing the temperature of the local area from rising. And static water is very easy to form a temperature gradient, and the overall heat transfer capacity is not as good as that of flowing water. It can be known that the heat dissipation effect is better and the efficiency is higher after adding the micro liquid pump 300.
[0044] According to Figure 3 and 4 As shown, a plurality of flow guiding members 140 are provided inside the heat dissipation cavity 110. A flow channel is formed between the two flow guiding members 140. Specifically, the flow guiding member 140 can interrupt the straight-line flow of the liquid, increasing the tortuosity and turbulence intensity of the flow. This can effectively increase the convective heat transfer coefficient between the liquid and the heat dissipation surface, and at the same time can also increase the convective heat transfer coefficient, thereby enhancing the heat dissipation effect and increasing the heat dissipation efficiency. The flow guiding member 140 can be cylindrical ( Figure 3 ), strip-shaped ( Figure 4 ), etc.
[0045] According to Figure 4As shown, a liquid pump driving board 310 is provided on the micro liquid pump 300, and a power supply (not shown) is provided on the heat dissipation body 100. The power supply is electrically connected to the liquid pump driving board 310. Specifically, the liquid pump driving board 310 is a control unit. When the power consumption of the electronic product is not high and the heat generation is less, only passive heat dissipation is required, and there is no need to turn on the micro liquid pump 300. When the electronic product operates with high power consumption and generates more heat, the micro liquid pump 300 can be turned on at this time for efficient heat dissipation. It can be understood that a power supply compartment (not shown) is provided inside the heat dissipation body 100, the power supply is arranged in the power supply compartment, and the power supply compartment is partitioned from the heat dissipation cavity 110.
[0046] According to Figures 1-5 As shown, the heat dissipation body 100 is made of a heat-conducting material. Specifically, only a heat-conducting material can transfer the heat of the electronic product to the heat dissipation body 100 to the greatest extent by means of solid conduction, and then the heat is dissipated through the heat dissipation body 100. The heat-conducting material can be aluminum alloy, and can be any material that can conduct heat, such as PC, magnesium alloy, copper material, etc. Aluminum alloy is preferred because aluminum alloy is light in weight and good in heat-conducting performance. As a wearable device, weight is a relatively important consideration factor.
[0047] In Embodiment 1, the micro liquid pump 300 is located outside the heat dissipation body 100. The shape of the heat dissipation body 100 can be arbitrary, and can be square, such as Figure 1 and Figure 2 shown; it can be circular, such as Figure 3 and Figure 4 shown. It can also be any other shape, which is within the protection scope of the present utility model.
[0048] Embodiment 2
[0049] As Figure 5 shown, in Embodiment 2, the micro liquid pump 300 is located inside the heat dissipation body 100. A liquid cooling film 150 is provided inside the heat dissipation body 100, and a heat dissipation cavity 110 is formed between the liquid cooling film 150 and the inner wall of the heat dissipation body 100. The micro liquid pump 300 is provided on the liquid cooling film 150, and the micro liquid pump 300 is used to make the heat dissipation substance in the flow pipeline 210 and the heat dissipation cavity 110 flow. A heat dissipation flow channel 151 is engraved on one side of the liquid cooling film 150 close to the heat dissipation cavity 110. Specifically, through the compressed flow channel design, a heat dissipation flow channel 151 is engraved on one side of the liquid cooling film 150 close to the heat dissipation cavity 110, which can interrupt the linear flow of the liquid, increase the tortuosity of the flow and the turbulence intensity. This can effectively improve the convective heat transfer coefficient between the liquid and the heat dissipation surface, and at the same time can also improve the convective heat transfer coefficient, thereby enhancing the heat dissipation effect and increasing the heat dissipation efficiency.
[0050] It can be understood that the liquid cooling film 150 can improve the heat transfer efficiency between the liquid and the heat dissipation surface, thereby increasing the heat dissipation efficiency. Both ends of the flow pipe 210 are connected to the heat dissipation cavity 110 through two connectors 160 respectively.
[0051] In Embodiment 2, the rest is the same as that in Embodiment 1.
[0052] Embodiment 3
[0053] As Figure 6 shown, a partition plate 170 is provided inside the heat dissipation body 100. The partition plate 170 divides the inside of the heat dissipation body 100 into two parts, namely a cavity 180 and a heat dissipation cavity 110. A semiconductor refrigerator 190 is provided inside the cavity 180.
[0054] Specifically, one end close to the semiconductor refrigerator 190 is the heat source. The heat absorption end of the semiconductor refrigerator 190 is closely adjacent to the heat source. The heat dissipation end is closely adjacent to the heat dissipation cavity 110. The heat dissipation cavity 110 takes away the heat of the semiconductor refrigerator 190 to achieve the purpose of temperature reduction. The semiconductor refrigerator 190 and liquid cooling are combined for heat dissipation, with better heat dissipation effect and higher heat dissipation efficiency, and can achieve the purpose of quickly cooling electronic products.
[0055] In Embodiment 3, the rest is the same as that in Embodiment 1.
[0056] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, its architecture form can be flexible and changeable, and a series of products can be derived. Just making several simple deductions or substitutions should be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
