Description

Technical Field

[0001] This utility model relates to a radiator, specifically a radiator for a gas generator set, belonging to the field of generator set technology. Background Technology

[0002] When a gas generator set is running, there are multiple heat sources that need to be cooled simultaneously: Coolant: Gas internal combustion engines generate a lot of heat when they are working, which must be cooled by coolant to prevent the engine from overheating and being damaged.

[0003] Lubricating oil: The temperature of engine lubricating oil will rise during lubrication and circulation. Excessive oil temperature will cause its viscosity to decrease, lubrication performance to fail, and engine wear to accelerate.

[0004] Compressed air: Most gas generator sets use turbocharging technology. When air is compressed, its temperature rises sharply, causing its density to decrease and affecting combustion efficiency. Therefore, an intercooler is necessary to cool this high-temperature compressed air.

[0005] Traditional gas generator sets typically use independent radiators or separate designs for coolant, lubricating oil, and booster air, resulting in complex system structures, dispersed layouts, and low integration of heat dissipation for multiple media. Radiators often rely on forced cooling by fans, which directly blow air onto the heat sink, creating significant airflow resistance and relatively high fan power consumption.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] This utility model addresses the shortcomings of the prior art by providing a gas generator set radiator that can solve the problems of low integration of heat dissipation for multiple media, high airflow resistance, and high energy consumption during the heat dissipation process.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: The radiator for a gas generator set includes a water inlet chamber, an oil inlet chamber, and an air inlet chamber connected end to end, forming a ring structure. A return water chamber, an oil return chamber, and a return air chamber are installed directly below the water inlet chamber, oil inlet chamber, and air inlet chamber, connected end to end. A heat dissipation core is installed between the water inlet chamber and the return water chamber, the oil inlet chamber and the oil return chamber, and the air inlet chamber and the return air chamber. A conical shell is fixedly installed on the inner ring of the ring structure formed by the water inlet chamber, oil inlet chamber, and air inlet chamber. A vertically oriented straight cylindrical shell is fixedly installed on the conical shell, and an upward-drawing axial flow fan is installed at the bottom of the inner cavity of the straight cylindrical shell.

[0009] Furthermore, a supporting circular plate is fixedly installed on the inner ring of the annular structure formed by the water return chamber, oil return chamber, and air return chamber.

[0010] Furthermore, support legs are installed at the bottom of the support circular plate.

[0011] Furthermore, the heat dissipation core includes a water-cooled core, an oil-cooled core, and an intercooler core.

[0012] Furthermore, the water diffuser core is located between the water inlet chamber and the water return chamber and is connected to both chambers; the oil diffuser core is located between the oil inlet chamber and the oil return chamber and is connected to both chambers; the intercooler core is located between the air inlet chamber and the air return chamber and is connected to both chambers.

[0013] Furthermore, a water inlet is provided at the middle position above the water inlet chamber, an oil inlet is provided at the middle position above the oil inlet chamber, and an air inlet is provided at the middle position above the air inlet chamber.

[0014] Furthermore, a water return port is provided at the middle position below the water return chamber, an oil return port is provided at the middle position below the oil return chamber, and an air return port is provided at the middle position below the air return chamber.

[0015] Furthermore, the conical shell is provided with a large-diameter end and a small-diameter end, with the small-diameter end located above the large-diameter end.

[0016] Furthermore, the straight cylindrical shell and the conical shell are arranged coaxially.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: By integrating water, oil, and gas heat dissipation channels into a single ring unit, a high degree of integration of heat dissipation for the three media is achieved, simplifying the system structure and making it suitable for generator set installations in space-constrained environments. The flow path of the three media is top-in and bottom-out, which, together with the bottom-in and top-out of the cooling air, forms a highly efficient counter-current heat exchange relationship, resulting in a large temperature difference and high heat exchange efficiency. By using a conical and cylindrical shell design, the natural upward trend of hot air is utilized to assist the axial flow fan in drawing air, reducing airflow resistance, lowering the fan power requirement, improving heat dissipation efficiency, and saving energy.

[0022] like Figures 1-3 As shown in the figure, this utility model provides a radiator for a gas generator set, including a water inlet chamber 1, an oil inlet chamber 2, and an air inlet chamber 3 connected end to end, forming a ring structure; a return water chamber 4, an oil return chamber 5, and an air return chamber 6 connected end to end are installed directly below the water inlet chamber 1, the oil inlet chamber 2, and the air inlet chamber 3; a heat dissipation core 7 is installed between the water inlet chamber 1 and the return water chamber 4, between the oil inlet chamber 2 and the oil return chamber 5, and between the air inlet chamber 3 and the air return chamber 6.

[0023] The heat dissipation core 7 includes a water diffuser, an oil diffuser, and an intercooler core, which are used for cooling high-temperature coolant, high-temperature lubricating oil, and high-temperature pressurized air, respectively. The water diffuser core is located between the water inlet chamber 1 and the water return chamber 4 and communicates with both chambers. The oil diffuser core is located between the oil inlet chamber 2 and the oil return chamber 5 and communicates with both chambers. The intercooler core is located between the air inlet chamber 3 and the air return chamber 6 and communicates with both chambers.

[0024] A water inlet 8 is provided at the middle position above the water inlet chamber 1, an oil inlet 9 is provided at the middle position above the oil inlet chamber 2, and an air inlet 10 is provided at the middle position above the air inlet chamber 3.

[0025] A water return port 11 is provided at the middle position below the water return chamber 4, an oil return port 12 is provided at the middle position below the oil return chamber 5, and an air return port 13 is provided at the middle position below the air return chamber 6.

[0026] A conical shell 14 is fixedly installed on the inner ring of the annular structure formed by the water inlet chamber 1, oil inlet chamber 2, and air inlet chamber 3. The conical shell 14 has a large-diameter end and a small-diameter end, with the small-diameter end located above the large-diameter end. A vertically oriented cylindrical shell 15 is fixedly installed on the small-diameter end of the conical shell 14, and the cylindrical shell 15 is coaxially arranged with the conical shell 14. An axial flow fan 16 for upward air extraction is installed at the bottom of the inner cavity of the cylindrical shell 15. Hot air flows from bottom to top, utilizing the chimney effect, which can reduce airflow resistance and improve heat dissipation efficiency.

[0027] The inner ring of the annular structure formed by the water return chamber 4, oil return chamber 5, and air return chamber 6 is fixedly installed with a supporting circular plate 17, and a supporting leg 18 is installed at the bottom of the supporting circular plate 17.

[0028] The specific working principle of this utility model is as follows: The three high-temperature media each have their own independent inflow, heat dissipation, and return channels, and they do not mix with each other.

[0029] Engine coolant path: High-temperature coolant enters from inlet 8 → inlet chamber 1 → water distributor core → return chamber 4 → flows out from return inlet 11 and returns to the engine.

[0030] Lubricating oil path: High-temperature engine oil flows from oil inlet 9 → oil inlet chamber 2 → oil diffuser core → oil return chamber 5 → out from oil return port 12 and returns to the engine lubrication system.

[0031] Boost air path: The high-temperature boost air compressed by the turbocharger flows from the intake port 10 → intake chamber 3 → intercooler core → return chamber 6 → out through the return port 13 and enters the engine intake manifold.

[0032] Forced air cooling and efficient exhaust: The axial flow fan at the top starts and draws in ambient cold air from the bottom. The cold air passes horizontally through all three heat dissipation cores, carrying away the heat from the fins. The heated air, after absorbing heat, gathers in the conical and straight shells and is discharged upwards at high speed into the atmosphere under the combined action of the fan's suction and the chimney effect.

[0033] The flow path of the three media is top-in and bottom-out, which, together with the bottom-in and top-out of the cooling air, forms a highly efficient counter-current heat exchange relationship, resulting in a large temperature difference and high heat exchange efficiency.
