Description

Technical Field

[0001] This invention relates to the field of heat pump unit condenser technology, specifically to an automatic gas-liquid separation condenser for heat pump units. Background Technology

[0002] A condenser is a component of a refrigeration system and a type of heat exchanger. It converts gas or vapor into liquid, rapidly transferring heat from the tubes to the surrounding air. The condenser's operation is exothermic, hence its relatively high temperature. Power plants use numerous condensers to condense the steam discharged from turbines. In refrigeration plants, condensers are used to condense refrigeration vapors such as ammonia and Freon. In the petrochemical industry, condensers are used to condense hydrocarbons and other chemical vapors. In distillation processes, devices that convert vapor into liquid are also called condensers. All condensers operate by removing heat from gases or vapors.

[0003] When a heat pump unit's condenser releases heat, the internal gas condenses into liquid and tends to accumulate at the bottom of the condenser tube along the inner wall. Excessive liquid accumulation can form small seals inside the pipe, affecting the smooth flow of gas. This increases the resistance to airflow at the bottom of the condenser tube, leading to pipe vibration due to impeded gas flow and affecting the pipe's lifespan. Therefore, heat pump units need to use automatic gas-liquid separators to promptly discharge the condensed liquid at the bottom of the condenser tube, preventing liquid accumulation from affecting pipe flow and ensuring smooth gas flow.

[0027] Please see Figure 1-7 An automatic gas-liquid separator condenser for a heat pump unit includes: a frame 1 and a pipe support frame 2. The pipe support frame 2 is fixedly connected to the inner wall of the frame 1. A condensing pipe mechanism is installed inside the pipe support frame 2. A liquid collection mechanism is fixedly installed on the inner bottom wall of the frame 1. A gas-liquid separator is fixedly installed above the liquid collection mechanism. Multiple gas-liquid separators are located at the bottom of the condensing pipe mechanism. A liquid level control mechanism and a buoyancy follower mechanism are respectively installed inside the gas-liquid separator. The buoyancy follower mechanism is located on one side of the liquid level control mechanism. A water seal auxiliary mechanism is installed at the bottom of the liquid level control mechanism. A partition 10 is fixedly connected to the inner wall of the frame 1. The number of partitions 10 is... There are two partitions 10, with the two partitions 10 located on both sides of the condensing pipe mechanism. Through the frame 1, pipe support frame 2, condensing pipe mechanism, liquid collection mechanism, gas-liquid separation mechanism, liquid level control mechanism, buoyancy driven mechanism and water seal auxiliary mechanism, the condensed heat-conducting refrigerant liquid can be collected at the bottom through the liquid box 501, ensuring the unobstructed flow of the inside of the three-way pipe 504 and facilitating gas flow. At the same time, the heat-conducting refrigerant liquid retained inside the liquid box 501 and the sealing block 704 form a seal to prevent the leakage of heat-conducting refrigerant gas. This ensures that the heat-conducting refrigerant liquid condensed at the bottom of the condensing pipe 301 is discharged in time, preventing the heat-conducting refrigerant liquid from accumulating and affecting the unobstructed flow of the condensing pipe 301, and ensuring the smooth flow of heat-conducting refrigerant gas.

[0028] The condensing pipe mechanism includes a condenser pipe 301, an inlet pipe 302, and an outlet pipe 303. The condenser pipe 301, inlet pipe 302, and outlet pipe 303 are all fixedly installed on the inner wall of the pipe support frame 2. There are multiple condenser pipes 301, and the shape of each condenser pipe 301 is U-shaped. The inlet pipe 302 and outlet pipe 303 are located on both sides of the multiple condenser pipes 301 to increase the gas travel and ensure the heat dissipation effect.

[0029] The liquid-gathering mechanism includes a liquid-gathering tank 401 and a liquid-guiding pipe 402. The liquid-gathering tank 401 is fixedly connected to the inner bottom wall of the frame 1, and the liquid-guiding pipe 402 is fixedly installed at the bottom of the frame 1. The interior of the liquid-guiding pipe 402 is connected to the inner wall of the liquid-gathering tank 401, and one end of the liquid-guiding pipe 402 is fixedly connected to the outer wall of the drain pipe 303 so that the overflowing heat-conducting refrigerant liquid can be concentrated and discharged into the drain pipe 303.

[0030] The gas-liquid separation mechanism includes a liquid box 501, an upper connecting plate 502, a lower connecting plate 503, and a three-way pipe 504.

[0031] The gas-liquid separation mechanism also includes a guide plate 505, which is integrally set on the upper surface of the lower connecting plate 503. The liquid box 501 is filled with heat-conducting refrigerant liquid so that the guide plate 505 can guide the heat-conducting refrigerant liquid to the water seal auxiliary mechanism, ensuring that even a small amount of liquid can achieve liquid sealing and forming a liquid seal insurance.

[0032] The liquid level control mechanism includes a connecting frame plate 601, an overflow pipe 602, a connecting column 603, and a guide channel 604. The connecting frame plate 601 is fixedly connected to the inner wall of the liquid box 501. The overflow pipe 602 is fixedly inserted into the inner wall of the lower connecting plate 503, and the bottom end of the overflow pipe 602 is connected to the interior of the liquid collection tank 401. The connecting column 603 is fixedly connected to the surface of the connecting frame plate 601. The guide channel 604 is embedded in the bottom end of the connecting column 603, and the overflow pipe 602 is connected to the inner wall of the liquid box 501. One end of 2 is located inside the guide channel 604, and a seepage gap is provided between the overflow pipe 602 and the guide channel 604. Through the frame plate 601, overflow pipe 602, connecting column 603 and guide channel 604, the maximum height of the liquid level can be controlled by the top height of the overflow pipe 602 through the siphon principle, and the minimum height of the liquid level can be controlled by the bottom cover of the guide channel 604, thereby controlling the liquid level of the heat transfer refrigerant and ensuring that gas is not directly discharged from the overflow pipe 602.

[0033] The buoyancy driven mechanism includes a liquid separator 701, a one-way plate 702, and a float 703. The liquid separator 701 is fixedly connected to the inner wall of the liquid box 501. The one-way plate 702 is rotatably connected to the upper surface of the liquid separator 701. The float 703 is fixedly connected to the upper surface of the one-way plate 702 so as to control the opening and closing of the one-way plate 702 by buoyancy, and at the same time form one-way conduction to ensure that gas flows out from the three-way pipe 504.

[0034] The buoyancy driven mechanism also includes a sealing block 704 and a drain hole 705. The sealing block 704 is fixedly connected to the bottom of the one-way plate 702. The drain hole 705 is opened through both sides of the liquid-separating plate 701. The shape and size of the drain hole 705 match the shape and size of the sealing block 704. The drain hole 705 is located above the guide plate 505 to facilitate liquid drainage and the closure of the drain hole 705.

[0035] The water seal auxiliary mechanism includes a fixed frame 801, a refrigerant liquid adsorption sponge 802, an inlet tank 803, and a drain tank 804. The fixed frame 801 is fixedly connected between the connecting frame plate 601 and the lower connecting plate 503. The inlet tank 803 and the drain tank 804 are respectively opened on both sides of the fixed frame 801. The refrigerant liquid adsorption sponge 802 is fixedly connected inside the fixed frame 801 so that when the liquid is very low, the refrigerant liquid adsorption sponge 802 can evenly adsorb a small amount of liquid into the interior, thereby forming a liquid seal on one side of the drain tank 804, thus forming a double liquid seal.

[0036] Among them, the frame 1 is internally fixedly connected with a support strip 9, and the support strip 9 is located on one side of the condensation pipe mechanism. The surface of the partition 10 is provided with a waist-shaped hole 11 to facilitate the passage of external heat dissipation airflow.

[0037] Working principle: During use, the heat-conducting refrigerant gas enters the three-way pipe 504 from the liquid inlet pipe 302, then enters the liquid box 501, and is then drawn into the condenser pipe 301 by the rear compressor. It then enters the next three-way pipe 504, and so on, until it exits from the drain pipe 303 after passing through the last three-way pipe 504. At this time, an external fan blows airflow to dissipate heat from the condenser pipe 301, liquid inlet pipe 302, and drain pipe 303. Some of the heat-conducting refrigerant gas condenses into heat-conducting liquid after its heat decreases, and over time, it flows along the condenser pipe 301, liquid inlet pipe 302, drain pipe 303, and three-way pipe 504 into the liquid box 501. As the amount of condensate increases, the buoyancy of the float 703 increases, causing it to float and drive the one-way disc 702 to unfold. The drain hole 705 becomes unobstructed, and the liquid flows down from the drain hole 705 and into the bottom... The heat-conducting refrigerant liquid retained by the unit merges. As time goes on, the amount of heat-conducting refrigerant liquid inside the liquid box 501 gradually increases, and the liquid level gradually rises until the liquid level reaches the highest point of the overflow pipe 602. When the liquid level reaches the highest point of the overflow pipe 602, the liquid flows out from the overflow pipe 602 until the liquid level is lower than the bottom of the guide groove 604. At the same time, the buoyancy of the one-way plate 702 disappears and it closes. During the above steps, the liquid level is always higher than the height of the drain trough 804, thus forming a liquid seal at the bottom to prevent gas from leaking from the overflow pipe 602. The liquid level is always lower than the height of the three-way pipe 504, thus ensuring that the airflow channel is not blocked by liquid, ensuring smooth passage, and reducing the vibration caused by the water column impacting the pipe. At the same time, all the liquid overflowing from the overflow pipe 602 enters the liquid collection tank 401 and enters the outlet end of the drain pipe 303 along the guide pipe 402 to mix with the gas and finally enter the rear compressor to participate in the main pipeline heat delivery.
