[0031] As Figures 1 to 9 shown, the heat exchange device of this embodiment includes a main body 1, a heat dissipation member 2, and a fixing device 3. The fixing device 3 includes a screw 31 and a heat insulation sleeve 32. The heat insulation sleeve 32 is sleeved on the screw 31. The heat dissipation member 2 is connected to the heat insulation sleeve 32, and the heat dissipation member 2 is fixedly installed on the main body 1 through the screw 31.
[0032] It can be understood that the heat exchange device can be a neck-mounted air conditioner / fan or a handheld air conditioner / fan, etc., which uses semiconductor refrigeration technology for heat exchange. In this embodiment, a neck-mounted air conditioner is taken as an example for illustration. The heat insulation sleeve 32 is internally provided with internal threads, so that the heat insulation sleeve 32 can be spirally sleeved on the screw 31 to prevent the heat insulation sleeve 32 from shaking up and down and keep the structure stable. In other embodiments, the heat insulation sleeve 32 can also be sleeved on the screw 31 by interference fit, which can also prevent shaking up and down. The heat dissipation member 2 is fixed on the main body 1 through the screw 31. The heat dissipation member 2 is used to transfer heat to the hot surface, and then the heat is taken away by the fan arranged on the hot surface, so as to achieve heat exchange.
[0033] Among them, a heat insulation sleeve 32 is arranged on the screw 31, and then the heat dissipation member 2 is connected to the heat insulation sleeve 32, so as to prevent the heat of the heat dissipation member 2 from being transferred to the heat conduction member 12 and the refrigeration member 13 through the screw 31, and prevent the refrigeration member 13 from being damaged. Thermal runaway refers to the phenomenon that the heat accumulation inside or around the thermoelectric cooler is sufficient to cause an unexpected sharp temperature rise.
[0034] In a possible embodiment, as Figure 8 and Figure 9 shown, the heat insulation sleeve 32 includes a first heat insulation part 321 and a second heat insulation part 322 with different diameters. The heat dissipation member 2 includes a connecting part 21. The screw 31 fixes the connecting part 21 on the main body 1, and the connecting part 21 is sleeved on the second heat insulation part 322.
[0035] Among them, the outer diameter dimension of the first heat insulation part 321 is larger than that of the second heat insulation part 322, and the first heat insulation part 321 is far from the nut 311 of the screw 31. A connection hole adapted to the second heat insulation part 322 is provided on the connection part 21 of the heat dissipation part 2. By inserting the connection part 21 into the second heat insulation part 322, the first heat insulation part 321 can prevent the heat dissipation part 2 from falling off due to the influence of gravity.
[0036] In a possible embodiment, as Figure 4 shown, the fixing device 3 further includes a washer 33. The washer 33 is sleeved on the screw 31, and the connection part 21 is arranged between the washer 33 and the first heat insulation part 321.
[0037] Specifically, the screw 31 includes a nut 311 and a stud 312. The washer 33 is sleeved on the stud 312 through the second heat insulation part 322, and the washer 33 is located between the nut 311 and the connection part 21.
[0038] It can be understood that in other embodiments, the washer 33 can also be directly sleeved on the stud 312 of the screw 31. In this embodiment, the washer 33 is sleeved on the second heat insulation part 322 and is located between the nut 311 and the connection part 21. By heat insulation of the washer 33, the heat of the heat dissipation part 2 can be prevented from being transferred to the nut 311 above the connection part 21, effectively avoiding heat leakage between the nut 311 and the heat dissipation part 2.
[0039] In a possible embodiment, as Figure 9 shown, a spring 34 is sleeved on the stud 312. One end of the spring 34 abuts against the nut 311 of the screw 31, and the other end of the spring 34 abuts against the washer 33, or the screw 31 is a spring screw.
[0040] It can be understood that the spring 34 can be sleeved on an ordinary hardware screw 31, or the spring 34 and the screw 31 can be an integral spring screw. In this embodiment, the spring screw is taken as an example for illustration. By changing the rigid connection between the connection part 21 of the heat dissipation part 2 and the heat conduction part 12 to a flexible connection with the spring screw, there is a spring 34 buffer during the tightening of the spring screw, and the heat dissipation part 2 is not directly pressed by the nut 311; by using the spring screw to tightly press the heat dissipation part 2 and the heat conduction part 12 more closely, while avoiding rigid collision, the connection is more stable, and the better the heat dissipation effect of the heat dissipation part 2 on the refrigeration part 13, the better the refrigeration effect of the refrigeration part 13.
[0041] In a possible embodiment, the upper and lower end faces of the connection part 21 respectively abut against the washer 33 and the first heat insulation part 321. By limiting the upper and lower positions of the connection part 21 through the washer 33 and the first heat insulation part 321, the heat dissipation part 2 can be prevented from shaking up and down, ensuring the stability of the heat dissipation part 2.
[0042] In a possible embodiment, the outer diameter dimension of the washer 33 is greater than or equal to the outer diameter dimension of the nut 311, so that the washer 33 can completely cover the nut 311, ensuring isolation between the connecting portion 21 and the nut 311 and preventing the heat of the heat dissipation member 2 from being transferred to the nut 311; specifically, in this embodiment, the outer diameter dimension of the washer 33 is equal to the outer diameter dimension of the nut 311, making the overall appearance more beautiful.
[0043] In a possible embodiment, the heat insulation sleeve 32 and the washer 33 are made of heat insulation materials. Specifically, the heat insulation sleeve 32 and the washer 33 are plastic parts. The heat insulation sleeve 32 and the washer 33 are used to prevent the heat of the heat dissipation member 2 from being transferred to the temperature guiding member 12 and the refrigerating member 13 through the screw 31. Therefore, the heat insulation sleeve 32 and the washer 33 need to be made of heat insulation materials, such as materials like fiberglass, asbestos, rock wool, silicate, etc.
[0044] In a possible embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, the heat dissipation member 2 further includes a substrate 22 and heat dissipation fins 23. The heat dissipation fins 23 are installed on the substrate 22, and the connecting portion 21 is fixedly connected to the substrate 22.
[0045] Among them, the main body 1 includes a housing 11, a temperature guiding member 12, and a refrigerating member 13. The temperature guiding member 12 is connected to the housing 11, the refrigerating member 13 is connected to the temperature guiding member 12, the refrigerating member 13 is disposed between the temperature guiding member 12 and the heat dissipation member 2, and the heat dissipation member 2 is threadedly connected to the housing 11 or the temperature guiding member 12 through the screw 31.
[0046] It can be understood that the refrigerating member 13 is disposed on the temperature guiding member 12, the substrate 22 of the heat dissipation member 2 is located above the refrigerating member 13 and faces the refrigerating member 13, for heat exchange with the refrigerating member 13, and the heat dissipation fins 23 dissipate heat. The refrigerating member 13 is cooled by a radiator to enhance the refrigerating effect of the refrigerating member 13. In Figure 5 the upper part, the parts are the hot surfaces, and the hot surfaces transfer the heat of the heat dissipation member 2 to the fan, and the fan then blows away the heat. The heat dissipation member 2 is sleeved on the heat insulation sleeve 32 of the screw 31, so that the heat of the heat dissipation member 2 cannot be transferred through the screw 31.
[0047] In a possible embodiment, the temperature guiding member 12 is provided with an internally threaded hole column 121, and the screw 31 is threadedly screwed into the internal threaded hole of the internally threaded hole column 121.
[0048] Among them, the heat conduction member 12 and the housing 11 are integrally connected. A threaded hole column 121 is provided on the heat conduction member 12. The stud 312 of the screw 31 is threadedly screwed into the internal threaded hole of the internal threaded hole column 121, so that the heat dissipation member 2 is stably installed above the heat conduction member 12. At the same time, the heat insulation sleeve 32 can prevent the heat dissipation member 2, the heat conduction member 12, and the refrigeration member 13 provided on the heat conduction member 12 from heat leakage.
[0049] The neck-mounted air conditioner provided in the above embodiment of the present application has at least the following characteristics:
[0050] 1. An insulating sleeve 32 and a washer 33 that can isolate heat transfer are provided between the heat dissipation member 2 and the screw 31, so as to prevent the heat of the heat dissipation member 2 from being transferred to the heat conduction member 12 and the refrigeration member 13 through the screw 31, thereby avoiding heat leakage between the cold surface and the hot surface through the screw 31 and preventing the refrigeration member 13 from being damaged.
[0051] 2. The rigid connection between the heat dissipation member 2 and the heat conduction member 12 is changed to a flexible connection through the spring 34, which not only avoids rigid collision but also makes the connection more stable.
[0052] The above description is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
