Abstract
Description
Technical Field
[0001] This utility model relates to the field of condenser equipment technology, and more specifically, to a condenser with the subcooling zone positioned at the top. Background Technology
[0002] In existing conventional condenser designs, the subcooling zone is usually located at the bottom. This is achieved by adding a liquid storage tank. After the gas-liquid mixed refrigerant enters the tank, the liquid portion of the refrigerant sinks due to gravity, while the gaseous portion, with its lower density, rises to form a liquid surface. The liquid refrigerant then flows through the subcooling zone of the condenser, cooling down again to become subcooled liquid refrigerant. However, in new energy vehicles, the location and shape of the radiator grille opening, the obstruction by the anti-collision beam, and the arrangement of the front heat exchanger can obstruct the subcooling zone, preventing the refrigerant from achieving proper heat dissipation. This can lead to insufficient subcooling or reheating of the refrigerant, causing refrigerant vaporization. The main solution is to move the subcooling zone from the bottom to the top of the condenser, thus avoiding obstruction. However, since the liquid refrigerant is at the bottom due to gravity, it cannot flow directly from the bottom to the top subcooling zone, reducing the device's effectiveness. Therefore, this invention designs a condenser with the subcooling zone positioned at the top to solve the aforementioned problems. Utility Model Content
[0003] 1. Technical problems to be solved
[0004] The purpose of this invention is to provide a condenser with a top-mounted subcooling zone to solve the problems mentioned in the background section.
[0005] In new energy vehicles, the location and shape of the radiator grille opening, the obstruction of the anti-collision beam, and the arrangement of the front heat exchanger can all lead to the obstruction of the subcooling zone, preventing the refrigerant from achieving proper heat dissipation. This can result in insufficient subcooling temperature of the refrigerant or secondary heating of the refrigerant, causing refrigerant vaporization. The main solution is to move the subcooling zone of the condenser from the bottom to the top, thus avoiding obstruction. However, liquid refrigerant is at the bottom due to gravity and cannot flow directly from the bottom channel to the top subcooling zone, thereby reducing the effectiveness of the device.
[0006] 2. Technical Solution
[0007] A condenser with a top-mounted subcooled zone includes a liquid storage tank. The outer side of the liquid storage tank has a gas-liquid mixing inlet and a subcooled liquid outlet. The subcooled liquid outlet is located above the gas-liquid mixing inlet. A liquid storage tank baffle is fixedly connected to the inner wall of the liquid storage tank. A drain pipe is fixedly connected to the outer side of the liquid storage tank baffle. One end of the drain pipe passes through the liquid storage tank baffle and extends outward, and the other end of the drain pipe is connected to a filter assembly.
[0008] Preferably, the filtration assembly includes a water guide pipe fixedly connected to the drain pipe, an installation component fixedly connected to the outer side of the water guide pipe, an installation groove formed on the outer side of the installation component, and a filter screen fixedly connected to the inner cavity of the installation groove. This allows the gas-liquid mixed refrigerant to be automatically filtered after entering the liquid storage tank, thereby filtering out impurities and non-condensable gases, improving the purity of the refrigerant, reducing wear on the compressor and other key components, and extending the service life of the entire refrigeration system.
[0009] Preferably, the partition of the liquid storage tank is located between the gas-liquid mixing inlet and the subcooled liquid outlet, so that when the gas-liquid mixed refrigerant enters the liquid storage tank, it can automatically separate the gas-liquid mixed refrigerant from the subcooled liquid in the liquid storage tank, thereby preventing the gas-liquid mixed refrigerant from mixing with the subcooled liquid and thus improving the refrigeration efficiency of the device.
[0010] Preferably, the two ends of the liquid storage tank are fixedly connected with a cap and a plug, respectively, thereby improving the sealing performance of the device and preventing leakage of gas-liquid mixed refrigerant and supercooled liquid inside the liquid storage tank.
[0011] Preferably, a condenser flow baffle is fixedly connected to the outside of the liquid storage tank, thereby reducing the pressure loss before the expansion valve and the static liquid column loss when the liquid is supplied to the upper part, and preventing the compressor from having a wet stroke.
[0012] 3. Beneficial effects
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] 1) In this utility model, by setting a diversion pipe, the pressure generated by the flow of gas-liquid mixed refrigerant will force the liquid refrigerant through the filter component into the diversion pipe 5, thereby allowing the diversion pipe 5 to transport the liquid refrigerant to the top of the liquid storage tank, avoiding the liquid refrigerant being at the bottom due to gravity and unable to flow directly from the bottom channel to the top subcooling zone, thus improving the performance of the device.
[0015] 2) In this utility model, by setting a filter component, when the liquid refrigerant is located at the mounting part 7, the pressure generated by the flow of the gas-liquid mixed refrigerant will filter the liquid refrigerant through the filter screen 8, thereby filtering out impurities and non-condensable gases, thus improving the purity of the refrigerant, thereby reducing the wear of the compressor and other key components, and extending the service life of the entire refrigeration system.

[0020] Example: Please refer to Figure 1-3 A condenser with a top-mounted subcooled zone includes a liquid storage tank 1. The outer side of the liquid storage tank 1 has a gas-liquid mixing inlet 2 and a subcooled liquid outlet 3. The subcooled liquid outlet 3 is located above the gas-liquid mixing inlet 2. A liquid storage tank partition 4 is fixedly connected to the inner wall of the liquid storage tank 1. A drain pipe 5 is fixedly connected to the outer side of the liquid storage tank partition 4. One end of the drain pipe 5 passes through the liquid storage tank partition 4 and extends outward, and the other end of the drain pipe 5 is connected to a filter assembly.
[0021] The filtration assembly includes a water guide pipe 6 fixedly connected to the drain pipe 5. An installation component 7 is fixedly connected to the outside of the water guide pipe 6. An installation groove is opened on the outside of the installation component 7. A filter screen 8 is fixedly connected to the inner cavity of the installation groove. This allows the gas-liquid mixed refrigerant to be automatically filtered after entering the liquid storage tank 1, thereby filtering out impurities and non-condensable gases, improving the purity of the refrigerant, reducing wear on the compressor and other key components, and extending the service life of the entire refrigeration system.
[0022] The liquid storage tank partition 4 is located between the gas-liquid mixing inlet 2 and the subcooled liquid outlet 3, so that when the gas-liquid mixed refrigerant enters the liquid storage tank 1, it can automatically separate the gas-liquid mixed refrigerant from the subcooled liquid in the liquid storage tank 1, thereby preventing the gas-liquid mixed refrigerant from mixing with the subcooled liquid and thus improving the refrigeration efficiency of the device.
[0023] The two ends of the liquid storage tank 1 are respectively fixedly connected with a plug 9 and a plug 10, thereby improving the sealing performance of the device and preventing the leakage of gas-liquid mixed refrigerant and supercooled liquid inside the liquid storage tank 1.
[0024] The outer side of the liquid storage tank 1 is fixedly connected to a condenser flow baffle 11, which enables the device to reduce the pressure loss before the expansion valve and the static liquid column loss when the liquid is supplied to the high position, thus preventing the compressor from having a wet stroke.
[0025] Working principle of this utility model:
[0026] When the gas-liquid mixed refrigerant enters the liquid storage tank 1, the liquid is located on the side closer to the filter assembly due to gravity, while the gas is located on the side of the liquid storage tank partition 4. At this time, as the gas-liquid mixed refrigerant continues to enter the inner cavity of the liquid storage tank 1, the pressure generated by the flow of the gas-liquid mixed refrigerant will force the liquid refrigerant through the filter assembly into the drain pipe 5, thereby allowing the drain pipe 5 to transport the liquid refrigerant to the top of the liquid storage tank.
[0027] When the liquid refrigerant is located at the mounting component 7, the pressure generated by the flow of the gas-liquid mixed refrigerant will force the liquid refrigerant through the filter screen 8, thereby filtering out impurities and non-condensable gases, improving the purity of the refrigerant, reducing wear on the compressor and other key components, and extending the service life of the entire refrigeration system.
