Description

Technical Field

[0001] This utility model relates to the field of wearable air conditioning technology, specifically to an air conditioning device and a wearable air conditioner. Background Technology

[0002] Air conditioners, as indispensable cooling / heating devices in modern life, provide people with a comfortable living environment. However, due to the limitations of their fixed installation, people who work or engage in outdoor activities, such as field workers, traffic police, cleaners, and industrial workers, cannot effectively regulate their bodies under extreme weather conditions. Especially in the hot summer and cold winter, these workers not only face challenges in their working environment but may also face health risks such as heatstroke.

[0003] To address this issue, an innovative air-conditioning garment has emerged on the market. Designed specifically for outdoor workers, this garment integrates clothing and air conditioning equipment to actively regulate body temperature. The garment primarily consists of two parts: the clothing itself and the air conditioning unit. The clothing incorporates heat-conducting channels that connect to the heat exchange chamber of the air conditioning unit, forming a complete heat exchange loop. This loop is filled with a heat exchange medium that circulates under the drive of a circulation pump. As the heat exchange medium flows through the heat exchange chamber, it exchanges heat with a cold / hot source, absorbing or releasing heat. This heat-exchanged medium continues to flow, transferring the cooling or heating energy to the clothing and ultimately acting on the body to regulate body temperature.

[0004] However, despite the significant convenience that air-conditioned clothing provides for outdoor workers, current market products still have some design shortcomings. Specifically, the inlet and outlet of the circulating pump, which connects to the heat exchange chamber, are both located at the bottom of the chamber. This design results in insufficient flow of the heat exchange medium within the chamber, particularly between the upper and lower sections, where the lower section's heat exchange medium is hotter than the upper section, thus affecting heat transfer efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an air conditioning device and a wearable air conditioner.

[0006] This utility model discloses an air conditioning device, comprising:

[0007] The outer shell has a heat exchange chamber containing a heat exchange medium;

[0008] A circulating pump, mounted on a casing, has a first inlet, a first outlet, a second inlet, and a second outlet. The first inlet and the first outlet are connected to a heat exchange chamber, and the second inlet and the second outlet are connected to a heat exchange channel in an air-conditioned garment.

[0009] A heat exchange source is detachably installed inside the heat exchange chamber, and the heat exchange source comes into contact with the heat exchange medium to exchange heat.

[0010] When the heat exchange source is a cold source, the first inlet is connected to an outlet pipe, and the outlet of the outlet pipe extends to the upper part of the heat exchange chamber; when the heat exchange source is a heat source, the first outlet is connected to an inlet pipe, and the inlet of the inlet pipe extends to the upper part of the heat exchange chamber.

[0011] According to one embodiment of the present invention, both the first inlet and the first outlet are arranged in the lower part of the heat exchange chamber.

[0012] According to one embodiment of the present invention, the second inlet and the second outlet are respectively connected to universal joints, and the second inlet and the second outlet are respectively connected to the heat exchange channel through the universal joints.

[0013] According to one embodiment of the present invention, the circulating pump is a brushless motor circulating pump, and the motor part of the circulating pump is arranged outside the housing.

[0014] According to one embodiment of the present invention, water is used as the heat exchange medium.

[0015] According to one embodiment of the present invention, the outer shell includes a shell and a cover. The inner cavity of the shell forms a heat exchange cavity and communicates with the opening of the shell. The cover is detachably disposed on the opening.

[0016] According to one embodiment of the present invention, a buckle is hinged on the cover, and a flange is provided on the housing, with the buckle and the flange engaging and connecting.

[0017] The present invention discloses a wearable air conditioner, including an air-conditioning garment and an air-conditioning device as described above. The air-conditioning garment is provided with a heat exchange channel, the input end of which is connected to a second inlet, and the output end of which is connected to a second outlet.

[0018] Compared with the prior art, the air conditioning device and wearable air conditioner of this utility model have the following advantages:

[0019] In this invention, when the heat exchange source is a cold source, a water outlet pipe is installed at the first outlet, allowing the higher-temperature heat exchange medium to flow back to the upper part of the heat exchange chamber. This, in turn, allows the lower-temperature heat exchange medium located in the lower part of the heat exchange chamber to preferentially flow into the heat exchange channel. When the heat exchange source is a heat source, a water inlet pipe is installed at the first inlet, allowing the higher-temperature heat exchange medium located in the upper part of the heat exchange chamber to preferentially flow into the heat exchange channel. The higher-temperature heat exchange medium then flows back to the lower part of the heat exchange chamber, thereby improving heat transfer efficiency. The heat exchange medium can absorb or release heat more quickly when flowing through the heat exchange chamber, thus enhancing the cooling / heating performance of the air conditioning equipment.

[0028] Example 1

[0029] This embodiment provides an air conditioning device, see [link]. Figures 1 to 3The air conditioning unit comprises a housing 100, a circulating pump 200, and a heat exchange source 300. The housing 100 has a heat exchange chamber 110, which contains a heat exchange medium. The circulating pump 200 is located at the bottom of the housing 100 and has a first inlet 210, a first outlet 220, a second inlet 230, and a second outlet 240. The first inlet 210 communicates with the second outlet 240, and the first outlet 220 communicates with the second inlet 230. The first inlet 210 and the first outlet 220 are located at the lower part of the heat exchange chamber 110 and communicate with it. The second inlet 230 and the second outlet 240 communicate with the heat exchange channel of the air-conditioned garment. The heat exchange source 300 is detachably disposed within the heat exchange chamber 110, and the heat exchange source 300 contacts the heat exchange medium for heat exchange.

[0030] The heat exchange chamber 110 and the heat exchange channel of the air-conditioned clothing form a heat exchange circuit. Driven by the circulating pump 200, the heat exchange medium circulates in the heat exchange circuit. The circulation direction of the heat exchange medium is as follows: heat exchange chamber 110, first outlet 220, second inlet 230, heat exchange channel, second outlet 240, first inlet 210, heat exchange chamber 110. In specific applications, the circulating heat exchange medium exchanges heat with the heat exchange source 300 when it flows through the heat exchange chamber 110. After the heat exchange, the heat exchange medium carries cold or heat and transfers the cold or heat to the human body when it flows through the heat exchange channel.

[0031] Review Figure 2 and 3 When the heat exchange source 300 is a cold source, the first inlet 210 is connected to the outlet pipe 250, and the outlet of the outlet pipe 250 extends to the upper part of the heat exchange chamber 110. During the circulation of the heat exchange medium, the heat exchange medium flowing through the heat exchange channel absorbs heat and releases cold energy. Therefore, the heat exchange medium output from the heat exchange channel will have a higher temperature. The higher temperature heat exchange medium flows back to the upper part of the heat exchange chamber 110 through the second outlet 240, the first inlet 210, and the outlet pipe 250 in sequence. This causes the higher temperature heat exchange medium to accumulate in the upper part of the heat exchange chamber 110, while the lower temperature heat exchange medium accumulates in the lower part of the heat exchange chamber 110. Since the first outlet 220 is arranged in the lower part of the heat exchange chamber 110, the lower temperature heat exchange medium flows into the heat exchange channel preferentially, thereby improving the heat transfer efficiency.

[0032] Similarly, when the heat exchange source 300 is the heat source, the first outlet 220 is connected to a water inlet pipe, and the inlet of the water inlet pipe extends to the upper part of the heat exchange chamber 110. During the circulation of the heat exchange medium, the heat exchange medium flowing through the heat exchange channel releases heat, so the heat exchange medium output from the heat exchange channel will have a lower temperature. The lower temperature heat exchange medium flows back to the lower part of the heat exchange chamber 110 through the second outlet 240 and the first inlet 210 in sequence. This causes the lower temperature heat exchange medium to accumulate in the lower part of the heat exchange chamber 110, while the higher temperature heat exchange medium accumulates in the upper part of the heat exchange chamber 110. Since the inlet of the water inlet pipe is arranged in the upper part of the heat exchange chamber 110, the higher temperature heat exchange medium preferentially flows into the heat exchange channel.

[0033] Review Figure 2 The outer casing 100 includes a shell 120 and a cover 130. The inner cavity of the shell 120 forms a heat exchange chamber 110 and communicates with the opening 121 of the shell 120. The cover 130 is detachably installed on the opening 121 of the shell 120 to close the heat exchange chamber 110. The cover 130 has latches 131 hinged around its periphery, and the outer periphery of the shell 120 has a flange 122. When the cover 130 is placed on the opening 121 of the shell 120 and the latches 131 are engaged with the flange 122, the cover 130 is installed on the shell 120. This structure allows the cover 130 to better seal the heat exchange chamber 110, preventing the heat exchange medium inside the heat exchange chamber 110 from flowing out.

[0034] In this embodiment, the circulating pump 200 is a brushless motor circulating pump 200, which can arrange the motor part outside the housing 120 to achieve water and electricity separation, avoid the energy storage medium in the heat exchange chamber 110 from contacting the motor part, ensure the working safety of the motor part, greatly reduce the failure rate of the motor part, and thus extend the service life of the circulating pump 200.

[0035] In this embodiment, the second inlet 230 and the second outlet 240 are respectively connected to universal joints 260. The second inlet 230 and the second outlet 240 are respectively connected to the heat exchange channel through universal joints 260 to avoid pipe entanglement.

[0036] In this embodiment, water is used as the heat exchange medium, which has the characteristics of wide availability, low cost, high specific heat capacity, and good stability.

[0037] In summary, when the heat exchange source of this air conditioning equipment is a cold source, by setting a water outlet pipe at the first outlet, the higher temperature heat exchange medium can flow back to the upper part of the heat exchange chamber through the water outlet pipe, and then the lower temperature heat exchange medium located in the lower part of the heat exchange chamber will preferentially flow into the heat exchange channel. When the heat exchange source of this air conditioning equipment is a heat source, by setting a water inlet pipe at the first inlet, the higher temperature heat exchange medium located in the upper part of the heat exchange chamber will preferentially flow into the heat exchange channel through the water inlet pipe, and the higher temperature heat exchange medium will flow back to the lower part of the heat exchange chamber, thereby improving the heat transfer efficiency. The heat exchange medium can absorb or release heat more quickly when flowing through the heat exchange chamber, thereby enhancing the cooling / heating performance of the air conditioning equipment.
