Description

Technical Field

[0001] This utility model belongs to the field of wearable cooling equipment technology, specifically relating to a ventilation and cooling device, a cooling backpack, and a cooling suit. Background Technology

[0002] The principle of semiconductor refrigeration technology is based on the thermoelectric effect, which refers to the phenomenon where, at the contact point of two different materials, heating one side generates a voltage difference on the other side. This phenomenon is called the "thermoelectric effect." A refrigeration system is constructed using a semiconductor refrigeration device as the core cooling component. This system is formed by connecting cold and hot end heat exchangers to the cold and hot ends of the semiconductor refrigeration device. The hot end heat exchanger exchanges heat with the ambient space, while the cold end heat exchanger cools the load. The cooling capacity of the semiconductor refrigeration device can be controlled by adjusting its operating voltage / current. Semiconductor refrigeration devices, with their miniaturization, high reliability, high efficiency, and environmental friendliness, provide suitable application scenarios for semiconductor refrigeration technology in specific environments or regions.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] Example: like Figure 1-8 As shown, this embodiment provides a ventilation and cooling device, including a cooling module 1, a ventilation module 2, and a support module 3; The cooling module 1 comprises a semiconductor cooling chip 101, a cooling plate 102, a heat sink 103, a cooling fan 104, an electronic control board 105, a cooling housing, and a cooling mounting base 108. The semiconductor cooling chip 101, the heat sink 103, the cooling fan 104, and the electronic control board 105 are disposed inside the cooling housing. The electronic control board 105 is electrically connected to the semiconductor cooling chip 101 and the cooling fan 104, respectively. The cooling plate 102 is disposed on the outer end face of the housing. The cold end face and the hot end face of the semiconductor cooling chip 101 are respectively attached and fixed to the cooling plate 102 and the heat sink 103. The cooling housing is provided with an air inlet 109 and an air outlet 110. The cooling mounting base 108 is connected to the cooling housing. The support module 3 is provided with a mating hole 301 that cooperates with the ventilation module 2, a ventilation duct 302 that communicates with the mating hole 301, and a recessed clearance 303. The size of the recessed clearance 303 is larger than the size of the cooling module 1.

[0022] Specifically, ventilation module 2 is a turbine fan device or an axial fan device.

[0023] Specifically, the cooling housing includes a first cooling housing 106 and a second cooling housing 107. The first cooling housing 106 and the second cooling housing 107 together form a mounting cavity for mounting a semiconductor cooling chip 101, a heat sink 103, a cooling fan 104, and an electronic control board 105. A cooling fin 102 is disposed on the outer end face of the second cooling housing 107. An air inlet vent 109 is disposed around the side of the second cooling housing 107, and an air outlet vent 110 is disposed on the top of the first cooling housing 106. The refrigeration mounting base 108 has a circular structure and is threadedly connected to the first refrigeration housing 106 to form an installation space.

[0024] The ventilation and cooling device of this embodiment can be installed in a backpack to form a cooling backpack or in clothing to form a cooling garment, thereby effectively solving the problems of people's work activities in high-temperature outdoor environments: on the one hand, the cooling plate 102 of the cooling module 1 provides cooling to regulate the body temperature in a small local space or area that comes into contact with the human skin; on the other hand, the ventilation module 2 provides a comfortable airflow effect to areas that are not in contact with the body, accelerating the evaporation of sweat caused by the increased body temperature due to the hot and humid weather, thereby improving the comfort of the human body.

[0025] In this embodiment, the cooling module 1 and the ventilation module 2 can be powered by a portable power bank, making them easy to carry and greatly improving the user's ease of operation and use.

[0026] The air inlet vent 109 and the air outlet vent 110 are located in two different spaces on the cooling housing, which can prevent hot airflows from crossing and short-circuiting, thus affecting the heat dissipation effect and achieving complete isolation between the cold area and the hot airflow field area, meeting the cooling needs of local space / area.

[0027] The specific structure of the cooling backpack, as described above, is as follows: This embodiment also discloses a cooling backpack, including a backpack body 4 and the aforementioned ventilation and cooling device; The backpack body 4 is provided with a first assembly part 401 for assembling the refrigeration module 1 and a second assembly part 402 for assembling the support module 3. The first assembly part 401 has a hole-like structure and cooperates with the refrigeration housing and the refrigeration mounting base 108; The second assembly part 402 is a cavity structure, the support module 3 is located inside the second assembly part 402, and the second assembly part 402 is provided with a backpack ventilation hole 403 that communicates with the cavity structure of the second assembly part 402. The cooling module 1, located on the backpack body 4, is positioned above the ventilation module 2, and the cooling module 1 is located within the recessed clearance space 303.

[0028] Multiple cooling modules 1 and ventilation modules 2 can be installed on the backpack body 4; The cooling module 1 has a cooling plate 102 that protrudes from the back end of the backpack body 4 and can directly contact the user's back, thereby providing cooling to regulate body temperature. The ventilation module 2 on the support module 3 can take in air from the cavity of the second assembly part 402 and then take out air from the backpack ventilation hole 403 of the backpack body 4, forming a ventilation convection method to achieve convective heat exchange in areas other than the cooling module 1, accelerate heat dissipation, and improve the body's cooling sensation and comfort.

[0029] Furthermore, the support module 3 and the interior of the backpack body 4 can form an airflow isolation space. On the one hand, this can prevent the air outlet 110 of the cooling module 1 from sticking to the back of the backpack body 4 and blocking the flow of hot air, thus affecting the heat dissipation effect. On the other hand, it can prevent the blockage of the air inlet of the ventilation module system from affecting the external airflow entering the backpack body 4 through the ventilation module system and being blown out to the back of the human body to achieve the effect of convection cooling.

[0030] The specific structure of the cooling suit, as described above, is as follows: This utility model also discloses a cooling suit, including a cooling suit body 5 and the aforementioned ventilation and cooling device; The cooling suit body 5 is provided with a third assembly part 501 for assembling the refrigeration module 1 and a fourth assembly part for assembling the support module 3. The third assembly part 501 has a hole-like structure and cooperates with the refrigeration housing and the refrigeration mounting base 108; The fourth assembly part includes a mesh layer 502, a closed outer layer 503, and a breathable inner layer 504. The closed outer layer 503 and the breathable inner layer 504 are connected to form a cavity structure for placing the support module 3. The mesh layer 502 is connected to the closed outer layer 503. The closed outer layer 503 is provided with an outer layer through hole 5031 corresponding to the position of the cooling module 1 and the ventilation module 2. The breathable inner layer 504 is provided with an inner layer through hole 5041 corresponding to the position of the cooling module 1.

[0031] In the above structure, the planar area of ​​the cooling plate 102 is raised relative to the breathable inner layer 504 of the cooling suit. When the cooling suit is worn normally, the raised cooling plate 102 first contacts the human body to form a close-fitting cooling method, thereby achieving the effect of local cooling of the human body. Moreover, the cooling module 1 can be set at one or more locations on the cooling suit corresponding to the temperature-sensitive areas of the human body (such as the area near the heart on the spine and the temperature-sensitive areas on the left and right sides of the abdomen) according to different application scenarios and needs. Meanwhile, the protruding cooling pad 102 fits snugly against the human body, creating an airflow isolation space between the breathable inner layer 504 and the human body. On the one hand, this prevents the breathable inner layer 504 from blocking the airflow of the ventilation duct 302 of the support module 3 due to its close contact with the body, thus affecting the effect of convective accelerated evaporation and cooling. On the other hand, it effectively reduces the increased wind resistance of the ventilation duct 302 due to the blockage of the breathable holes 5042 on the breathable inner layer 504. Through the airflow isolation space, external airflow can be effectively injected into the cooling garment 5 through the ventilation module 2 and delivered to the back of the human body through the corresponding breathable holes 5042 on the breathable inner layer 504 to achieve the effect of convective cooling.

[0032] Multiple cooling modules 1 and ventilation modules 2 can be installed on the cooling suit body 5. (See reference...) Figure 8 .

[0033] In cooling suits, for cases where ventilation module 2 is a turbine fan device, there are two installation methods, as detailed below: You can refer to this. Figure 5 One end of the turbine fan device protrudes from the outer through hole 5031 of the closed outer layer 503. A fan cover 201 is provided at one end of the turbine fan device. The turbine fan device is fixed to the closed outer layer 503 through the fan cover 201. The other end is engaged with the mating hole 301 of the support module 3.

[0034] Or you can refer to Figure 6 One end of the turbine fan device is engaged with the outer through hole 5031, and the other end is connected and fixed with the mating hole 301 of the support module 3. This structure allows the turbine fan device and the support module 3 to be connected and form an integrated structure, which facilitates the overall installation and removal.

[0035] For the case where ventilation module 2 is an axial flow fan device, the installation method is as follows: One end of the axial fan device is provided with a fan mounting frame 202 and is fixed to the closed outer layer 503 through the fan mounting frame 202, and the other end is engaged with the mating hole 301 of the support module 3.

[0036] Specifically, the axial fan device is installed at the bottom of the back of the cooling garment body 5. There is a space between the other end of the axial fan device and the breathable inner layer 504, so that the axial fan device can be designed to be parallel or inclined to the ventilation duct 302 of the support module 3.

[0037] In the above structure, the problem of the air vents 5042 of the breathable inner layer 504 blocking the air outlet of the axial fan device and affecting the airflow volume, thus causing a decrease in the convective ventilation and cooling effect, can be avoided.

[0038] Specifically, one end of the breathable inner layer 504 extends to the top of the cooling garment body 5, which corresponds to the user's neck, allowing for more comprehensive cooling of all parts of the user's body.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
