Description

Technical Field

[0001] This utility model relates to the field of heat exchange device technology, specifically a dual-circulation heat exchange device for an air-cooled integrated cooling and heating unit. Background Technology

[0002] In many scenarios requiring temperature and cooling regulation, such as specific processes in industrial production, temperature control in commercial venues, and some special experimental environments, the demand for equipment that can flexibly achieve both cooling and heating functions is increasing.

[0003] Traditional heat exchangers are often single-function, capable of only one of the functions of cooling or heating, and cannot meet the flexible needs of heating and cooling regulation in diverse scenarios. Moreover, some dual-function heat exchangers have shortcomings in structural design and control methods, resulting in low heat exchange efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a dual-circulation heat exchange device for an air-cooled integrated heating and cooling unit to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dual-circulation heat exchange device for an air-cooled integrated cooling and heating unit, including a housing, a fan installed on the top of the housing, a support plate fixedly connected to the inner wall of the housing, a first heat exchanger and a second heat exchanger respectively installed on the left and right sides of the top of the support plate, a compressor and a control device installed on the bottom wall of the housing, a first conveying pipe and a second conveying pipe fixedly connected to the upper and lower ends of the front end of the compressor, and a solenoid valve installed at the front end of both the first conveying pipe and the second conveying pipe.

[0006] Preferably, multiple fans are provided, and the multiple fans are evenly distributed in a linear array on the top of the first heat exchanger and the second heat exchanger.

[0007] Furthermore, multiple fans are distributed on top of the first and second heat exchangers in a specific manner, specifically in a linear array. This distribution method enables the airflow generated by the fans to evenly cover the first and second heat exchangers, ensuring that all parts of the heat exchangers receive good ventilation and heat exchange effects, thereby improving heat exchange efficiency.

[0008] Preferably, the plurality of the fans are axial flow fans, with their air outlets facing upwards towards the first heat exchanger and the second heat exchanger.

[0009] Furthermore, many of the fans are axial flow fans. Axial flow fans are characterized by large flow rate and low air pressure, making them suitable for large-area ventilation and heat exchange scenarios. In addition, the air outlets of these axial flow fans face upwards towards the first and second heat exchangers. This outlet direction design allows the airflow generated by the fans to be directly blown onto the heat exchangers, enhancing the heat exchange between the air and the heat exchangers and further improving the heat exchange performance of the heat exchange device.

[0010] Preferably, the support plate is made of metal, the surface of the support plate is coated with an anti-corrosion coating, and the support plate is fixed to the inner wall of the box by bolts.

[0011] Furthermore, the support plate is made of metal, which has high strength and rigidity, providing stable and reliable support for the first and second heat exchangers. Additionally, an anti-corrosion coating is applied to the surface of the support plate, effectively preventing it from being corroded by environmental factors such as moisture and chemicals during long-term use, thus extending its service life. The support plate is fixed to the inner wall of the housing with bolts, a method that ensures secure installation and easy disassembly. When maintenance or replacement of components on the support plate is required, it can be easily removed, improving the maintainability of the equipment.

[0012] Preferably, the first heat exchanger and the second heat exchanger are finned heat exchangers, which are connected in parallel and respectively connected to the compressor through pipelines.

[0013] Furthermore, both the first and second heat exchangers are finned heat exchangers. By setting fins on the base tube, the heat exchange area of ​​the finned heat exchanger is greatly increased, which can significantly improve the heat exchange efficiency between air and refrigerant. The two are connected in parallel and are connected to the compressor through pipelines respectively. The parallel connection allows the two heat exchangers to work independently or simultaneously, and the heat exchange capacity can be flexibly adjusted according to different operating conditions, which improves the adaptability and working efficiency of the entire dual-cycle heat exchange device.

[0014] Preferably, the solenoid valve is a bidirectional solenoid valve, and its control signal line is electrically connected to the control device.

[0015] Furthermore, the solenoid valve is a bidirectional solenoid valve. A bidirectional solenoid valve has bidirectional flow capability, enabling it to change the refrigerant flow direction according to a control signal. This allows for different refrigerant circulation paths in the dual-cycle heat exchanger, meeting the needs of the integrated cooling and heating unit under different operating modes of cooling or heating. The solenoid valve's control signal line is electrically connected to the control device. Through this electrical connection, the control device can precisely control the opening, closing, and direction switching of the solenoid valve according to a preset program or received external commands, achieving automated control of the entire heat exchanger.

[0016] Preferably, the first and second conveying pipes are copper pipes, and both the first and second conveying pipes are wrapped with an insulation layer.

[0017] Furthermore, the first and second delivery pipes are made of copper. Copper has good thermal conductivity, which can quickly transfer the heat of the refrigerant and reduce heat loss during the delivery process. Both the first and second delivery pipes are wrapped with an insulation layer. The function of the insulation layer is to reduce the heat exchange between the refrigerant and the external environment during the delivery process and prevent the refrigerant from absorbing external heat or dissipating heat to the outside.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] First, before using the dual-circulation heat exchange device of the air-cooled integrated cooling and heating unit, ensure that the device is connected to the power supply, check whether the connections of each component are secure, and check for leaks in the pipeline. After confirming that everything is in order, turn on the power switch of the control device to put the entire device into standby mode. Set the required working mode through the control device, such as cooling mode or heating mode. The control device will send corresponding control signals according to the set mode. When the start signal is received from the control device, the compressor starts to work, compressing the refrigerant into a high-temperature, high-pressure gas. The control device controls the power supply according to the working mode. The opening and closing of the solenoid valve, a bidirectional solenoid valve, can change the refrigerant flow direction according to the control signal. In refrigeration mode, the control device controls the corresponding solenoid valve to open, allowing the high-temperature, high-pressure refrigerant gas to flow through either the first or second delivery pipe to one of the first or second heat exchangers, depending on the piping design and control strategy. In the heat exchanger, the refrigerant gas exchanges heat with the outside air, releasing heat, lowering its own temperature, and condensing into a liquid. Afterward, the liquid refrigerant flows back to the compressor or other related components such as throttling devices through the piping. Although not explicitly mentioned in the description, this is a common feature in actual refrigeration systems. Typically, to complete a refrigeration cycle, in heating mode, the control device changes the state of the solenoid valve, reversing the refrigerant flow. The high-temperature, high-pressure refrigerant gas flows to another heat exchanger, where it releases heat to the outside, achieving the heating function. The other heat exchanger acts as an evaporator, absorbing heat. The liquid refrigerant absorbs heat, evaporates into gas, and returns to the compressor to continue the cycle. Multiple fans are installed, evenly distributed in a linear array on top of the first and second heat exchangers. The fans are axial flow fans, with their outlets facing upwards towards the heat exchangers. During operation, the fans run continuously, [the system]... Outside air is blown towards the heat exchanger, accelerating heat exchange between the air and the heat exchanger and improving heat exchange efficiency. Whether in cooling or heating mode, the fan helps the heat exchanger to better transfer heat with the surrounding air, enhancing the cooling or heating effect. By setting the first and second heat exchangers in parallel and cooperating with a two-way solenoid valve and control device, flexible switching between cooling and heating modes is achieved. Users can choose the appropriate mode according to their actual needs to meet the cooling and heating requirements in different scenarios, improving the applicability and versatility of the device. Multiple axial flow fans are evenly distributed to enhance the heat exchange effect and improve heat dissipation conditions.

[0020] Secondly, the first and second conveying pipes of this utility model are made of copper pipes. Copper pipes have good thermal conductivity, which can reduce the heat loss of refrigerant during the transportation process and ensure the cooling or heating effect. At the same time, the insulation layer wrapped around the outside of the pipe can effectively prevent the external environment from affecting the temperature of the refrigerant inside the pipe, further improving energy utilization efficiency.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A dual-circulation heat exchange device for an air-cooled integrated cooling and heating unit includes a housing 1. A fan 101 is installed on the top of the housing 1. A support plate 102 is fixedly connected to the inner wall of the housing 1.

A compressor 105 and a control device 106 are installed on the bottom wall of the inner wall of the housing 1. A first delivery pipe 107 and a second delivery pipe 108 are fixedly connected to the upper and lower ends of the front end of the compressor 105, respectively. A solenoid valve 109 is installed at the front end of both the first delivery pipe 107 and the second delivery pipe 108.

[0030] Specifically, multiple fans 101 are provided, and the multiple fans 101 are evenly distributed in a linear array on the top of the first heat exchanger 103 and the second heat exchanger 104.

[0031] Specifically, the multiple fans 101 are axial flow fans 101, and their air outlets face upwards towards the first heat exchanger 103 and the second heat exchanger 104.

[0034] Specifically, the solenoid valve 109 is a bidirectional solenoid valve 109, and its control signal line is electrically connected to the control device 106.

[0035] Using the above technical solution, before using the dual-cycle heat exchanger of the air-cooled integrated cooling and heating unit, ensure that the device is connected to the power supply, check whether the connections of each component are secure, and check for leaks in the pipeline. After confirming that everything is correct, turn on the power switch of the control device 106 to put the entire device into standby mode. The internal wiring connections of the first heat exchanger 103, the second heat exchanger 104, the compressor 105, the control device 106, and the solenoid valve 109 are all existing well-known technologies in the art and will not be described in detail here. Set the required working mode through the control device 106, such as cooling mode or heating mode. The control device 106 will issue corresponding control signals according to the set mode. When the start signal is received from the control device 106, the compressor 105... 5. Upon startup, compressor 105 compresses the refrigerant, transforming it into a high-temperature, high-pressure gas. Control device 106 controls the opening and closing of solenoid valve 109 according to the operating mode. Solenoid valve 109 is a bidirectional solenoid valve, capable of changing the refrigerant flow direction based on control signals. In cooling mode, control device 106 controls the corresponding solenoid valve 109 to open, allowing the high-temperature, high-pressure refrigerant gas to flow through either the first delivery pipe 107 or the second delivery pipe 108 to either the first heat exchanger 103 or the second heat exchanger 104, depending on the piping design and control strategy. In the heat exchanger, the refrigerant gas exchanges heat with the outside air, releasing heat, lowering its own temperature, and condensing into a liquid. The liquid refrigerant then flows back through the piping. Although not explicitly mentioned in the description, compressor 105 or other related components such as throttling devices are typically present in actual refrigeration systems. To complete one refrigeration cycle, in heating mode, control device 106 changes the state of solenoid valve 109, reversing the refrigerant flow. The high-temperature, high-pressure refrigerant gas flows to another heat exchanger, where it releases heat to the outside, achieving the heating function. The other heat exchanger acts as an evaporator, absorbing heat. The liquid refrigerant absorbs heat and evaporates into gas, returning to compressor 105 to continue the cycle. Multiple fans 101 are provided, evenly distributed in a linear array on top of the first heat exchanger 103 and the second heat exchanger 104. The fans 101 are axial flow fans, with their outlets facing the heat exchangers. Above, during device operation, the fan 101 continuously operates, blowing outside air towards the heat exchanger, accelerating heat exchange between the air and the heat exchanger, and improving heat exchange efficiency. Whether in cooling or heating mode, the fan 101 helps the heat exchanger to better transfer heat with the surrounding air, enhancing the cooling or heating effect. By setting the first heat exchanger 103 and the second heat exchanger 104 in parallel connection, and with the cooperation of the bidirectional solenoid valve 109 and the control device 106, the flexible switching between the two working modes of cooling and heating is realized. Users can select the appropriate mode according to actual needs to meet the cooling and heating needs in different scenarios, improving the applicability and versatility of the device. Multiple axial flow fans 101 are evenly distributed to enhance the heat exchange effect and improve heat dissipation conditions.

[0038] Through the above technical solution, the first conveying pipe 107 and the second conveying pipe 108 are made of copper pipe. Copper pipe has good thermal conductivity, which can reduce the heat loss of refrigerant during the conveying process and ensure the cooling or heating effect. At the same time, the insulation layer wrapped on the outside of the pipe can effectively prevent the external environment from affecting the temperature of the refrigerant inside the pipe, and further improve energy utilization efficiency.
