Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, specifically to an oil separator heat exchange device. Background Technology

[0002] Air conditioning oil separators are a key component of refrigeration systems, used to separate the high-temperature, high-pressure mixed gas discharged from the compressor. The mixed gas usually contains refrigerant and lubricating oil. Since the vapor density of lubricating oil is different from that of refrigerant, the oil droplets are made to settle due to gravity by reducing the airflow speed. It is a common air conditioning accessory.

[0003] The air conditioning oil separator itself does not actively generate heat. Its heat mainly comes from the high-temperature and high-pressure mixed gas discharged from the compressor. The compressor exhaust temperature is usually as high as 110℃. Heat dissipation is achieved through natural dissipation, which is a serious problem of heat waste. The outer wall of the separator is in direct contact with the air, and a large amount of heat is lost to the environment through thermal radiation and thermal convection. This not only causes energy loss, but may also lead to local temperature rise in the workshop, increasing the additional energy consumption of ventilation and cooling equipment. Therefore, an oil separator heat exchange device is proposed. Utility Model Content

[0006] Preferably, the outer side of the connecting plate is provided with reinforcing ribs; a control panel is installed on the surface of the water storage tank, and an inlet pump and an outlet pump are installed on the control panel to control the flow of water in and out of the water storage tank.

The integrated control module on the control panel can monitor the temperature in real time. When the water temperature reaches the set threshold, the outlet pump will automatically start to output hot water. When the water level is lower than the lower limit, the inlet pump will automatically start to replenish water. No manual intervention is required, which reduces the difficulty of operation and avoids system failures caused by human error. Attached Figure Description

[0016] Example: Please see Figure 1-3 The present invention provides the following technical solution: An oil separator heat exchange device includes a connecting plate 1, a water storage tank 2, and a heat exchange cage 4; the water storage tank 2 is located at the bottom of the connecting plate 1, the heat exchange cage 4 is located at the top of the connecting plate 1, and the water storage tank 2, the connecting plate 1, and the heat exchange cage 4 are interconnected. The inner cavity of the connecting plate 1 has two water storage chambers, one above the other, and a connecting channel between the two water storage chambers. A water supply valve 8 is installed in the connecting channel. The upper water storage chamber is connected to the heat exchange cage 4, and the lower water storage chamber is connected to the water storage tank 2. The opening and closing of the two water storage chambers is controlled by the water supply valve 8. A bidirectional pump is connected to the water supply valve 8. A control panel 3 is installed on the surface of the water storage tank 2. The control panel 3 is equipped with an inlet pump and an outlet pump to control the flow of water in and out of the water storage tank 2. Reinforcing ribs are provided on the outside of the connecting plate 1. The heat exchange cage 4 includes a transverse exchange ring 5 and a longitudinal exchange tube 6. Multiple exchange rings 5 ​​are arranged and distributed vertically in sequence. The exchange tube 6 is perpendicular to the axis of the exchange ring 5 and is installed on the outside of the exchange ring 5. The inner cavities of the exchange ring 5 and the exchange tube 6 are interconnected. The bottom end of the exchange pipe 6 is installed on the connecting plate 1, and the exchange pipe 6 is connected to the water storage chamber above the connecting plate 1; The water storage tank 2 is cylindrical, and the water storage tank 2 and the connecting plate 1 have an installation hole in the middle. The heat exchange device can be sleeved on the outside of the oil separator using the installation hole. The heat exchange cage 4 is attached to the outer wall of the oil separator and exchanges heat with the liquid inside through heat conduction to achieve the purpose of cooling. The heat exchange cage 4 uses a thin and lightweight heat-conducting material. In addition, the inner walls of the water storage tank 2 and the connecting plate 1 are also equipped with heat-conducting layers, which can complete heat exchange more quickly and transmit the heated water out for easy reuse.

[0017] Working principle: The connecting plate, a disc-shaped central hub, serves as the device's central connection. Its internal cavity is axially divided into an upper and lower water storage chamber, connected by a vertically spaced connecting channel. A water supply valve is installed within this channel to control the flow between the two chambers. This valve is linked to a bidirectional pump, allowing for dynamic water flow distribution by adjusting the pump's forward and reverse rotation, moving the water from the upper chamber to the lower chamber or vice versa. In addition, the outer side of the connecting plate is equipped with reinforcing ribs made of high-strength alloy to enhance the connection stability between the connecting plate and the water storage tank and heat exchange cage, and to avoid structural deformation caused by water pressure or vibration during long-term use. The water storage tank is a cylindrical sealed container, vertically fixed to the bottom of the connecting plate. Its inner cavity is connected to the lower water storage cavity of the connecting plate, and it is used to store circulating water and temporarily store recovered heat. A control panel is installed on one side of the outer wall of the water storage tank. The panel integrates the inlet pump, outlet pump and control module. The inlet pump is connected to an external water source to replenish the water storage tank with new water, and the outlet pump is connected to external secondary heat-using equipment, such as a preheating system or heat tracing pipes, to output the hot water after absorbing heat. The control module can monitor the water temperature and water level in the storage tank in real time, and control the start and stop of the inlet pump, outlet pump and water delivery valve in a coordinated manner to achieve effective operation; The inner wall of the water bucket and the inner wall of the connecting plate are covered with a 0.5-1mm thick copper heat-conducting layer to improve the efficiency of heat conduction from the water to the bucket wall. The heat exchange cage is installed on the top of the connecting plate. It has a cage-like structure and is connected to the upper water storage chamber of the connecting plate. It is used to directly contact the outer wall of the oil separator and exchange heat. The exchange rings are made of thin aluminum-magnesium alloy and are arranged in parallel, one above the other, along the axial direction. The inner diameter of the exchange rings is matched with the outer diameter of the oil separator to ensure a tight fit. The exchange tubes are also made of aluminum-magnesium alloy, perpendicular to the axis of the exchange rings, and evenly distributed on the outside of each exchange ring. The inner cavity of the exchange tubes is connected to the inner cavity of the corresponding exchange rings to form a mesh flow channel. The bottom end of the exchange tubes is vertically fixed to the top of the connecting plate, and its inner cavity is connected to the upper water storage chamber, so that water can enter the exchange tubes and exchange rings through the upper water storage chamber to form an all-round heat exchange surface covering the outer wall of the oil separator. A circular mounting hole is coaxially formed between the center of the connecting plate and the water storage tank. The diameter of the mounting hole is slightly larger than the outer diameter of the oil separator. The entire device can be fitted onto the outside of the oil separator through the mounting hole, so that the heat exchange ring and heat exchange pipe of the heat exchange cage are tightly attached to the outer wall of the separator. The water storage tank is suspended below the separator. A separate circular bracket is installed below the water storage tank for support. Alternatively, it can be directly installed on the equipment frame through a fixing bracket. The cold water in the storage tank enters the upper storage chamber through the lower storage chamber and the water supply valve, and then flows into the heat exchanger tube and the heat exchanger ring. The water flows through the heat-conducting material of the heat exchanger and comes into contact with the outer wall of the oil separator, absorbing the heat of the high-temperature oil in the separator, and the water temperature rises. After absorbing heat, the hot water is transported from the upper water storage chamber to the lower water storage chamber via a bidirectional pump, and finally flows into the water storage tank. Multiple patch-type temperature sensors are distributed on the inner wall of the heat exchange cage, and the temperature sensors are electrically connected to the control module. When the control module detects that the water temperature has reached the set threshold, it starts the outlet pump to deliver the hot water to the secondary heat-using equipment, and at the same time starts the inlet pump to replenish cold water, thus completing the circulation.

[0018] The control module is based on a microprocessor (such as the STM32F4 series), equipped with a temperature sensor and an execution interface. A surface-mount temperature sensor is installed on the inner wall of the heat exchange cage, and a liquid level sensor and a temperature sensor are installed in the water storage tank. All of the above sensors are electrically connected to the control module, and their data are used as execution thresholds. The control panel is equipped with a human-machine interactive touch screen that displays monitoring data in real time and supports parameter setting and equipment execution operations.

[0019] This device is mainly used in the oil-liquid separation process in the field of air conditioning equipment. By recovering the waste heat released during the oil-liquid separation process, it realizes the cascade utilization of energy, which meets the requirements of energy conservation and environmental protection.

[0020] High-efficiency heat exchange: The heat exchange cage adopts a mesh structure design, with a large contact area with the outer wall of the oil separator. Combined with thin and light heat-conducting materials and an inner wall heat-conducting layer, the heat exchange efficiency is greatly improved compared with the traditional coil structure. Automated control: The control module adjusts the water flow rate and start / stop in real time to adapt to the dynamic temperature changes of the oil separator and avoid energy waste; Structural stability: The reinforcing rib design and high-strength materials ensure long-term stable operation of the device under high pressure and vibration environments; Secondary utilization: The recovered heat can be directly used for secondary applications, pipeline heating, and other scenarios, reducing energy consumption.
