[0001] The utility model relates to the technical field of temperature regulating devices, in particular to a portable temperature regulating device. Background Art

[0002] A typical example of a portable thermostat is a neck-hanging thermostat, which can generate energy through a semiconductor refrigeration chip. The cold or heat generated by the semiconductor refrigeration chip is transferred to the skin through a thermal conductor to achieve a contact cooling or heating effect. At the same time, a radiator is required to dissipate the energy (heat / cold) at the other end of the semiconductor refrigeration chip to obtain a better cooling or heating effect. In existing portable thermostats, a radiator is usually set corresponding to the semiconductor refrigeration chip. The fan blows air to the heat dissipation fins of the radiator. The airflow flows through the gaps between the heat dissipation fins to dissipate the energy on the heat dissipation fins. The bottom plate where the radiator contacts the semiconductor refrigeration chip is not blown directly, resulting in energy concentrated on the bottom plate of the radiator without timely dissipation. Therefore, the energy dissipation effect of the radiator in the existing portable thermostat is not good, which affects the energy generation effect of the semiconductor refrigeration chip.

[0003] Therefore, it is necessary to provide a portable temperature control device with better heat dissipation / cooling effect to achieve better energy saving effect. Utility Model Content

In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0032] like Figure 1 The embodiment of the utility model provides a portable temperature control device, specifically a neck-hanging temperature control device. The portable temperature control device includes a housing 10, a fan 20, a temperature control element 30, a heat sink 40 and a first air guide 51.

[0033] Reference Figure 1 The housing 10 has a first air inlet 102, referring to Figure 2 and Figure 4 The housing 10 also has a first air outlet 103. Figure 3 A wind duct 104 is formed between the first air inlet 102 and the first air outlet 103, and the wind duct 104 connects the first air inlet 102 and the first air outlet 103. Figure 2 and Figure 3 , the fan 20 is arranged in the air duct 104. The thermostat 30 is arranged on the housing 10. The radiator 40 is arranged in the air duct 104 and is located between the fan 20 and the first air outlet 103, the radiator 40 has a heat dissipation base plate 41, and the heat dissipation base plate 41 is thermally connected to the thermostat 30. Specifically, the thermostat 30 has a first temperature adjustment end, and the first temperature adjustment end is connected to the heat dissipation base plate 41. The radiator 40 also has a top 42 located on a side of the heat dissipation base plate 41 away from the thermostat 30. The first air guide 51 is arranged in the air duct 104, and the first air guide 51 is used to guide at least part of the airflow of the fan 20 to the heat dissipation base plate 41 of the radiator 40.

[0034] The thermostat 30 is, for example, a semiconductor refrigeration sheet, and the first thermostat end is the cold end or hot end of the semiconductor refrigeration sheet. When the cooling function of the portable thermostat is used, the first thermostat end is the hot end, and the radiator 40 is in thermal contact with the first thermostat end to conduct heat from the first thermostat end. The airflow blown to the radiator 40 by the fan 20 can contact the radiator 40 to take away the heat from the first thermostat end, thereby achieving heat dissipation of the thermostat 30. When the heating function of the portable thermostat is used, the first thermostat end is the cold end, and the radiator 40 is in thermal contact with the first thermostat end to conduct cold from the first thermostat end. The airflow blown to the radiator 40 by the fan 20 can contact the radiator 40 to take away the cold from the first thermostat end, thereby achieving heat dissipation of the thermostat 30. In this embodiment, the first air guide 51 can guide part of the airflow blown by the fan 20 to the heat sink 40 to the heat sink bottom plate 41, so that the airflow contacts the heat sink bottom plate 41 where the energy is concentrated as much as possible, thereby achieving a better heat dissipation / cooling effect of the heat sink and improving the energy efficiency of the thermostat. In this embodiment, the heat conduction connection refers to the two parts that can be connected by heat conduction to conduct heat or cold, which can be direct contact or indirect contact.

[0035] In some embodiments, the first end of the first air guide 51 is connected to the housing 10 and is located at a side of the radiator 40 away from the thermostat 30, and the second end of the first air guide 51 is located at an end of the first end away from the fan 20 and is arranged close to the heat dissipation base plate 41. It is understandable that the second end of the first air guide 51 is closer to the heat dissipation base plate 41 and farther away from the fan 20 than the first end, so that the first air guide 51 guides the airflow blown by the fan 20 to the radiator 40 to the heat dissipation base plate 41 along the direction from the first end to the second end. The first air guide 51 is, for example, arranged close to the top 42 of the radiator 40.

[0036] For example, the heat sink 40 has an air inlet end 43 and an air outlet end 44 that are arranged opposite to each other, and a heat dissipation gap that is connected to the air duct 104 is formed between the air inlet end 43 and the air outlet end 44. The air inlet end 43 is an end of the heat sink 40 close to the first air inlet 102, that is, an end of the heat sink 40 close to the fan 20. In some embodiments, referring to Figure 3 , the first air guide 51 is disposed between the fan 20 and the air inlet end 43, and can guide at least part of the airflow blown by the fan 20 to the radiator 40 to the air inlet end 43 in the direction close to the heat dissipation bottom plate 41, flow through the air outlet end 44 of the radiator 40, and finally blow out from the first air outlet 103. In other embodiments, the first air guide 51 can also be disposed between the air inlet end 43 and the air outlet end 44 (not shown), and can guide the airflow blown by the fan 20 to the radiator 40 at the rear end (the end close to the air outlet end 44) ​​of the radiator 40, so that the airflow contacts the heat dissipation bottom plate 41 as much as possible to dissipate heat / cooling, and then blows out from the first air outlet 103.

[0037] Among them, the shell 10 of the portable thermostat device is, for example, a U-shaped structure as a whole, and the shell 10 encloses a wearing cavity 101, and the user wears the portable thermostat on the neck. The thermostat 30 is, for example, a semiconductor refrigeration sheet, and the portable thermostat device also includes, for example, a thermal conductive member thermally connected to the second thermostat end of the thermostat 30 (the thermostat 30 is the cold end when the thermostat 30 uses the cooling function, and the thermostat 30 is the hot end when the thermostat 30 uses the heating function), and the thermal conductive member is arranged on the side of the thermostat 30 close to the wearing cavity 101. Specifically, the thermal conductive member is installed on the side of the shell 10 close to the wearing cavity 101, and the thermal conductive member is, for example, an aluminum alloy member or a thermally conductive silicone member. Through the contact between the thermal conductive member and the neck skin, the cold generated by the thermostat 30 can be transferred to the neck skin when the thermostat 30 is cooling to achieve a contact cooling effect, and the heat generated by the thermostat 30 can be transferred to the neck skin when the thermostat 30 is heating to achieve a contact heating effect. The first temperature regulating end of the temperature regulating element 30 is arranged near the air duct 104, wherein the fan 20 is, for example, a heat dissipation / cooling fan used solely for providing heat dissipation / cooling airflow to the radiator 40, then the first air inlet 102 is a heat dissipation / cooling air inlet used solely for the passage of heat dissipation / cooling airflow, the first air outlet 103 is a heat dissipation / cooling air outlet used solely for the passage of heat dissipation / cooling airflow, and the air duct 104 is a heat dissipation / cooling channel used solely for the passage of heat dissipation / cooling airflow. Of course, in some embodiments, the portable temperature regulating device also cools down by blowing out airflow. Then the fan 20 can be used as an airflow driving device that provides heat dissipation / cooling airflow to the radiator 40 and blows air to the user. At this time, the fan 20 is arranged in the air duct 104 and is located between the radiator 40 and the first air inlet 102. The first air inlet 102 can be shared as an air inlet for heat dissipation / cooling air flow and blowing air. For example, a second air outlet is also provided on the shell 10. The air duct 104 formed between the first air outlet 104 and the first air inlet 102 is a heat dissipation / cooling air duct, and a blowing air duct is formed between the second air outlet and the first air inlet. The heat dissipation / cooling air duct and the blowing air duct have common parts.

[0038] The first air inlet 102 can be disposed at multiple locations on the housing 10, such as Figure 1 As shown, the first air inlet 102, for example, includes a first sub-air inlet 1021 and a second sub-air inlet 1022, which are respectively arranged on different surfaces of the housing 10, so as to ensure the air intake and prevent the first air inlet 102 from being blocked by hair, etc. The first air outlet 103, for example, is arranged on a side of the housing 10 away from the wearing cavity 101. The first air outlet 103 is usually on the same side as the top 42 of the radiator 40, that is, the first air outlet 103 is arranged on a side of the radiator 40 away from the thermostat 30, and the first air guide 51 is also, for example, located on the same side of the radiator 40 away from the wearing cavity 101 as the first air outlet 103.

[0039] Since the heat dissipation base plate 41 of the radiator 40 is closer to the thermostat 30, the heat / cold of the thermostat 30 is mainly concentrated on the heat dissipation base plate 41 after being extracted by the radiator 40. The heat dissipation / cooling airflow contacts the radiator 40 and takes away the heat (or cold) in the process of entering from the air inlet end 43 and blowing out from the air outlet end 44. In the traditional setting, the heat dissipation / cooling airflow mainly contacts with the fins of the radiator for heat exchange, and cannot perform good heat dissipation / cooling of the heat dissipation base plate. In this embodiment, by setting the first air guide 51, at least part of the airflow blown by the fan 20 to the radiator 40 is guided to the heat dissipation base plate 41 of the radiator 40, so that the heat dissipation / cooling airflow passes through the area closer to the contact area between the radiator 40 and the thermostat 30 as much as possible, thereby taking away more heat / cold and achieving better heat dissipation / cooling effect, so that the thermostat 30 can achieve better energy-saving effect. In some embodiments, the first air guide 51 is tilted toward the direction close to the heat dissipation base plate 41 and the direction close to the air outlet end 44, that is, the first air guide 51 is tilted relative to the heat dissipation base plate 41 toward the direction close to the first air outlet 103 to achieve the guiding effect of the heat dissipation / cooling airflow, for example Figure 3 In the embodiment, the first air guide 51 is a plate structure tilted from the upper right to the lower left, so that the first air guide 51 can press the airflow blown in from the air inlet end 43 downward in the direction close to the heat dissipation base plate 41, thereby achieving the effect of guiding the heat dissipation / cooling airflow to the heat dissipation base plate 41. Alternatively, in some embodiments, the first air guide 51 can also be set as a tubular structure, so that the airflow blown out by the fan 20 flows through the tube cavity of the first air guide 51 and is guided to the heat dissipation base plate 41. When the first air guide 51 is a tubular structure, it can be set to an inclined state or a curved state, etc., and this embodiment is not limited thereto.

[0040] In some embodiments, reference Figure 3 , the maximum distance between the side of the radiator 40 away from the thermostat 30 (i.e., the top 42) and the heat dissipation bottom plate 41 is the radiator height H2, the distance between the end of the first air guide 51 close to the radiator 40 and the heat dissipation bottom plate 41 is the first height H1, and the first height H1 is less than or equal to two-thirds of the radiator height H2. Through the above arrangement, the heat dissipation / cooling air flow can be directed to the heat dissipation bottom plate 41 of the radiator 40 through the first air guide 51 while ensuring the air intake of the radiator 40, thereby ensuring the heat dissipation / cooling effect.

[0041] In some embodiments, the first air guide 51 is integrally formed with the housing 10. The housing 10, for example, includes an air duct shell for enclosing and forming the air duct 104, and the first air guide 51 is integrally formed with the air duct shell for example, which is convenient for manufacturing and assembly.

[0042] In some embodiments, the portable temperature control device further includes a second air guide 52, which is located between the radiator 40 and the first air outlet 103, and the second air guide 52 is inclined from the heat dissipation bottom plate 41 of the radiator 40 toward the first air outlet 103. Figure 3 As shown, the second air guide 52 is inclined from the heat dissipation base plate 41 of the radiator 40 along the direction from the lower right to the upper left, so that the heat dissipation / cooling airflow can be guided from the heat dissipation base plate 41 to the first air outlet 103, which can better guide the heat / cold.

[0043] In some embodiments, reference Figure 5 and Figure 6 The heat sink 40 includes a plurality of heat sink fins 46 extending from the heat sink base plate 41 toward a side away from the temperature regulating element 30 and spaced apart from each other. A heat sink gap communicating with the air duct 104 is formed between the plurality of heat sink fins 46. Figure 3 , Figure 4 and Figure 7 The portable temperature control device further includes a third air guide 53, which includes an air guide top plate 531. The air guide top plate 531 covers the side of the radiator 40 away from the temperature control member 30 (i.e., the top 42) and is arranged opposite to the heat dissipation bottom plate 41. By providing the air guide top plate 531, the heat dissipation / cooling airflow can be limited between the top 42 of the radiator 40 and the heat dissipation bottom plate 41, so that the heat dissipation / cooling airflow can better contact with the plurality of heat dissipation fins 46, thereby achieving a better heat dissipation / cooling effect.

[0044] In some embodiments, reference Figure 3 The third air guide member 53 further includes an extension portion 532, which is connected to one end of the air guide top plate 531 close to the fan 20 and extends toward the heat dissipation bottom plate 41. The extension portion 532 can further cover the air inlet end 43 of the radiator 40, thereby enhancing the effect of concentrating the heat dissipation / cooling airflow in the radiator 40.

[0045] In some embodiments, reference Figure 3 The end of the first air guide 51 close to the heat dissipation bottom plate 41 abuts against the end of the extension 532 away from the air guide top plate 531. This can prevent the heat dissipation / cooling airflow from directly entering the gap between the top 42 of the heat dissipation 40 and the housing 10 from the bottom of the first air guide 51 when entering the heat dissipation 40, ensuring that the heat dissipation / cooling airflow is pressed down to the heat dissipation bottom plate 41.

[0046] Reference Figure 4 , Figure 5 and Figure 7, the air inlet end 43 and the air outlet end 44 are arranged opposite to each other in the first direction, and the first direction is also the direction in which the heat dissipation / cooling airflow passes through the radiator 40, and the heat dissipation gap passes through the radiator 40 along the first direction. The third air guide member 53 also includes two air guide side plates 533 located on opposite sides of the air guide top plate 531 in the second direction, and the air guide top plate 531 and the two air guide side plates 533 surround the radiator 40, and the second direction is arranged crosswise with the first direction. The two air guide side plates 533 and the air guide top plate 531 realize a three-sided surrounding structure of the radiator 40 except for the heat dissipation bottom plate 41 and the air inlet end 43 and the air outlet end 44, which can concentrate the heat dissipation / cooling airflow in the radiator 40 for heat dissipation / cooling, and improve the contact effect between the heat dissipation / cooling airflow and the radiator 40, so as to improve the heat dissipation / cooling effect.

[0047] In some embodiments, reference Figure 6 , a recessed structure 431 is formed in the middle of the air inlet end 43. Specifically, for example, the lengths of the plurality of heat dissipation fins 46 of the radiator 40 are different, and the plurality of heat dissipation fins 46 are arranged along the second direction. The heat dissipation fins located in the middle area of ​​the arrangement direction among the plurality of heat dissipation fins 46 can be set shorter, and the ends can be retracted, or the inclination directions of the ends of the plurality of heat dissipation fins 46 can be set differently, so that a recessed structure 431 is formed at the air inlet end 43. Since the heat / cold amount in the middle of the thermostat 30 is higher, the recessed structure 431 is formed at the air inlet end 43 so that the heat dissipation / cooling airflow has less resistance when entering the radiator 40 from the recessed structure 431 when reaching the air inlet end 431, and has greater resistance when entering the radiator 40 from both sides of the recessed structure 431. Therefore, the flow rate of the heat dissipation / cooling airflow entering from the recessed structure 431 can be larger, and the heat dissipation / cooling can be concentrated on the middle of the radiator 40, thereby improving the heat dissipation / cooling effect.

[0048] In some embodiments, reference Figure 7 The portable temperature control device further includes a fourth air guide 54 disposed between the radiator 40 and the fan 20. The fourth air guide 54 is disposed corresponding to the air inlet end 43, and the fourth air guide 54 extends in the direction from the fan 20 to the radiator 40. The fourth air guide 54 is disposed so that the airflow blown out by the fan 20 is dispersed to both sides of the fourth air guide 54 instead of being concentrated on one side, so that the airflow reaching the air inlet end 43 of the radiator 40 is more uniform. For example, when the air inlet end 43 is further provided with a recessed structure 431, the fourth air guide 54 can also make the heat dissipation / cooling airflow better concentrated to enter from the recessed structure 431 when reaching the air inlet end 43, thereby improving the heat dissipation / cooling effect.

[0049] The portable temperature control device provided in the embodiment of the utility model guides the heat dissipation / cooling air flow to the heat dissipation base plate 41 of the radiator 40 through the first air guide member 51, and the heat dissipation / cooling air flow can be better guided out from the heat dissipation base plate 41 through the second air guide member 52. The heat dissipation / cooling air flow can be concentrated in the radiator 40 through the third air guide member 53 so as to better contact the radiator 40 for heat dissipation, and the heat dissipation of the middle area of ​​the radiator 40 can be better achieved through the recessed structure 431 and the fourth air guide member 54. Therefore, the portable temperature control device provided in this embodiment can achieve better heat dissipation / cooling effect, so that the temperature control member 30 can achieve better energy-control effect.
