Description

Technical Field

[0001] This utility model relates to the field of cooling equipment, and in particular to a wind-liquid mixed temperature control system unit. Background Technology

[0002] Current air conditioners generally come with a compressor system. Through the compressor and fan, the refrigerant undergoes physical state changes (liquid absorbs heat and vaporizes, gaseous state releases heat and liquefies) in the two evaporators and condensers. During these changes, heat is absorbed or released to achieve the effect of cooling or heating.

[0003] At this time, since heat absorption and dissipation need to be achieved through the physical state of the refrigerant, a compressor is required to control the changes in the physical state of the refrigerant. In this case, the power consumption of the air conditioner is high, resulting in higher operating costs. In specific environments, such as computer rooms with large indoor and outdoor temperature differences, where the indoor temperature is high and the outdoor temperature is relatively low, ordinary air conditioning units consume more energy. Utility Model Content

[0004] Therefore, it is necessary to provide a wind-liquid mixing temperature control system unit to address the problems in the existing technology.

[0005] A wind-liquid mixing temperature control system unit is characterized by comprising an indoor unit and an outdoor unit. The indoor unit is equipped with an indoor heat exchanger, and the outdoor unit includes an outdoor heat exchanger and a water pump. The indoor outlet of the indoor heat exchanger is connected to the outdoor inlet of the outdoor heat exchanger via a first pipe. The outdoor outlet of the outdoor heat exchanger is connected to one side of the water pump via a second pipe, and the other side of the water pump is connected to the indoor inlet of the indoor heat exchanger via a third pipe. The water pump is used to pump the cooling medium from the outdoor outlet to the indoor inlet. An outdoor fan is provided on the outside of the outdoor heat exchanger.

[0006] In one embodiment, the indoor heat exchanger includes an indoor inlet main pipe and an indoor outlet main pipe, with a heat-absorbing thin tube provided between the indoor inlet main pipe and the indoor outlet main pipe. The heat-absorbing thin tube is provided in several groups, and the upper and lower sides of the heat-absorbing thin tube are fixed by a fixing plate.

[0007] In one embodiment, the indoor water inlet pipe and the indoor water outlet pipe are provided with quick-release connectors at their ends, and the indoor water inlet pipe and the indoor water outlet pipe form an indoor water inlet and an indoor water outlet through the quick-release connectors at their ends.

[0008] In one embodiment, the outdoor unit further includes a housing, the outdoor heat exchanger is fixed to one side of the housing, the housing is open on one side of the outdoor heat exchanger, and the outdoor fan is located on the side of the outdoor heat exchanger.

[0009] In one embodiment, the outdoor heat exchanger includes an outdoor inlet main pipe and an outdoor outlet main pipe, with a plurality of outdoor thin pipes disposed between the outdoor inlet main pipe and the outdoor outlet main pipe. The outdoor inlet main pipe and the outdoor outlet main pipe are vertically arranged, and the outdoor thin pipes are horizontally arranged between the outdoor inlet main pipe and the outdoor outlet main pipe. The outdoor fan is located on the side of the outdoor thin pipes.

[0010] In one embodiment, the outdoor water inlet main is formed into an outdoor water inlet via a quick-release connector. The third pipe includes a third inner pipe and a third outer pipe. The third inner pipe is connected to the third outer pipe via a quick-release connector.

Many specific details are set forth in the following description to provide a full understanding of this utility model.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] like Figures 1 to 3 As shown, a wind-liquid mixed temperature control system unit is characterized by comprising an indoor unit and an outdoor unit. The indoor unit is equipped with an indoor heat exchanger 1, and the outdoor unit includes an outdoor heat exchanger 2 and a water pump 3. The indoor outlet 11 of the indoor heat exchanger 1 is connected to the outdoor inlet 21 of the outdoor heat exchanger 2 via a first pipe 4. The outdoor outlet 22 of the outdoor heat exchanger 2 is connected to one side of the water pump 3 via a second pipe 5, and the other side of the water pump 3 is connected to the indoor inlet 12 of the indoor heat exchanger 1 via a third pipe 6. The water pump 3 is used to pump the cooling medium from one side of the outdoor outlet 22 to the indoor inlet 12. An outdoor fan 23 is provided on the outside of the outdoor heat exchanger 2.

[0028] Water or a water-glycol solution is used as the cooling medium, which does not cause pollution during use. A water pump 3 is used as the power source for the circulation of the cooling medium. The cooling medium exchanges heat naturally in the indoor heat exchanger 1 and the outdoor heat exchanger 2. In the high-temperature indoor environment, the temperature of the cooling medium in the indoor heat exchanger 1 is lower than the ambient temperature. In the low-temperature outdoor environment, the temperature of the cooling medium in the outdoor heat exchanger 2 is consistently higher than the ambient temperature. An outdoor fan 23 is also installed. In this way, the indoor temperature can be reduced during the circulation of the cooling medium. At this time, the cooling medium is mainly driven by the water pump 3, which has low energy consumption and thus achieves the purpose of energy saving.

[0029] At this time, the indoor heat exchanger 1 is located in a high-temperature indoor environment. During use, the cooling medium flowing through the indoor heat exchanger 1 has a lower temperature, so heat transfer occurs between the high-temperature indoor air and the lower-temperature cooling medium. To improve the efficiency of heat transfer, in this embodiment, the indoor heat exchanger 1 includes an indoor inlet water main 13 and an indoor outlet water main 14. A heat-absorbing capillary tube 15 is provided between the indoor inlet water main 13 and the indoor outlet water main 14. Several sets of heat-absorbing capillary tubes 15 are provided, and the upper and lower sides of the heat-absorbing capillary tubes 15 are fixed by fixing plates. The multiple heat-absorbing capillary tubes 15 increase the contact area between the flowing cooling medium and the air, thereby increasing the efficiency of heat transfer. At the same time, the heat-absorbing capillary tubes 15 are connected through the indoor inlet water main 13 and the indoor outlet water main 14, so that the cooling medium can be collected and conveniently connected to the indoor water inlet 12 and the indoor water outlet 11.

[0030] Specifically, in order to facilitate the connection between the indoor water inlet 12 and the indoor water outlet 11 and the outdoor heat exchanger 2 via pipes, in this embodiment, quick-release connectors 7 are provided at the ends of the indoor water inlet main pipe 13 and the indoor water outlet main pipe 14. The indoor water inlet main pipe 13 and the indoor water outlet main pipe 14 form the indoor water inlet 12 and the indoor water outlet 11 through the quick-release connectors 7 at their ends. After the quick-release connectors 7 are provided, the indoor heat exchanger 1 can be quickly connected to the external pipes (first pipe 4 and third pipe 6), which makes the installation process more convenient and faster.

[0031] The outdoor unit is placed in the outdoor environment to transfer heat between a higher-temperature cooling medium and a lower-temperature, more stable external environment. In this embodiment, to improve the heat transfer efficiency of the cooling medium at the outdoor heat exchanger 2, the outdoor unit also includes a housing. The outdoor heat exchanger 2 is fixed to one side of the housing, and the housing has an open section on one side of the outdoor heat exchanger 2. The outdoor fan 23 is located on the side of the outdoor heat exchanger 2, and the air blown by the outdoor fan 23 acts on the main body of the outdoor heat exchanger 2, thereby accelerating the heat dissipation effect at the outdoor heat exchanger 2.

[0032] At this time, the outdoor heat exchanger 2 includes an outdoor inlet main pipe 24 and an outdoor outlet main pipe 25. A plurality of outdoor thin pipes 26 are arranged between the outdoor inlet main pipe 24 and the outdoor outlet main pipe 25. The outdoor inlet main pipe 24 and the outdoor outlet main pipe 25 are vertically arranged, and the outdoor thin pipes 26 are horizontally arranged between them. The outdoor fan 23 is located on the side of the outdoor thin pipes 26. The outdoor thin pipes 26 increase the contact area with the outside environment, thereby improving the efficiency of heat dissipation (heat exchange). Simultaneously, the outdoor inlet main pipe 24 and the outdoor outlet main pipe 25 facilitate connecting all the outdoor thin pipes 26 together. With the outdoor fans distributed along the sides of the outdoor thin pipes 26, the heat dissipation (heat exchange) efficiency at the location of the outdoor thin pipes 26 can be accelerated.

[0033] Meanwhile, for ease of installation, in this embodiment, the outdoor water inlet main pipe 24 is connected to an outdoor water inlet 21 via a quick-release connector 7. The third pipe 6 includes a third inner pipe 61 and a third outer pipe 62. The third inner pipe 61 is connected to the third outer pipe 62 via the quick-release connector 7. The third inner pipe 61 is connected to the water pump 3, and the third outer pipe 62 is connected to the indoor water inlet 12. Similarly, the quick-release connector 7 forms the connection structure for the outdoor unit, making connection to the indoor unit more convenient.

[0034] Regarding the connection method between the indoor and outdoor units, in this embodiment, the indoor water outlet 11 (corresponding to the quick-release connector 7) is connected to the outdoor water inlet 21 (corresponding to the quick-release connector 7) through the first pipe 4. The outdoor water outlet 22 is connected to the water pump 3 through the second pipe 5. The water pump 3 is connected to the quick-release connector 7 (water outlet) of the outdoor heat exchanger 2 through the third inner pipe 61, and then connected to the third outer pipe 62 through the connector. The other end of the third outer pipe 62 is connected to the indoor water inlet 12 (corresponding to the quick-release connector 7). Thus, from the outside, the outdoor unit and the indoor unit are connected through the first pipe 4 and the third outer pipe 62, thereby forming a cooling medium flowing between the two. During the installation process, it is only necessary to connect the two ends of the first pipe 4 and the third outer pipe 62 to the corresponding quick-release connectors 7 respectively, which is simple and convenient to install.

[0035] To ensure the normal operation of the temperature control system unit, in this embodiment, the second pipeline 5 is equipped with multiple branch pipes, each containing an exhaust valve 71, an expansion tank 72, a second water pressure sensor 73, a second needle valve 74, and a water replenishment ball valve 75. The second pipeline 5 also includes a series-connected three-way ball valve 76. The exhaust valve 71, installed on the branch pipes, allows gas to be released from the pipeline, preventing blockage. The expansion tank 72 adjusts the pressure within the pipeline, buffering the effects of pressure fluctuations. The second water pressure sensor 73 detects the pressure within the water pipe; alternatively, it can be connected in series within the second pipeline 5 to improve pressure detection accuracy. The second needle valve 74 facilitates maintenance. The water replenishment ball valve 75 allows connection to an external water source (cooling medium source) to replenish the cooling medium in the pipeline when needed.

[0036] Furthermore, the third inner pipe 61 is connected to a third temperature sensor 81 and a third water pressure sensor 82 via multiple branch pipes. A control ball valve 83 is connected in series in the third inner pipe 61. The third temperature sensor 81 can detect the stability of the corresponding pipe position, and the third water pressure sensor 82 can detect the water pressure at the corresponding position. At the same time, the third water pressure sensor 82 can also be connected in series in the third inner pipe 61 to improve the pressure detection accuracy. The control ball valve 83 can control the water flow switch in the corresponding pipe.

[0037] Finally, the first pipe 4 is connected to the first temperature sensor 91 and the first needle valve 92 via a branch pipe, which can detect the stability of the corresponding pipe position and facilitate maintenance.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
