[0033] Refer to Figures 1-5, an embodiment provided by the present utility model: an axial flow ring cooler, including a cooler housing 1, the longitudinal section of the cooler housing 1 is circular ring-shaped, a front-end header 2 is provided at the left end of the cooler housing 1, a front-end connecting pipe 201 is fixedly connected to the left end of the front-end header 2, a front-end connecting flange 202 is fixedly connected to the left end of the front-end connecting pipe 201, and other pipelines are connected through the front-end connecting flange 202. A rear-end header 3 is provided at the right end of the cooler housing 1, a rear-end connecting pipe 301 is fixedly connected to the right end of the rear-end header 3, a rear-end connecting flange 302 is fixedly connected to the right end of the rear-end connecting pipe 301, and other pipelines are connected through the rear-end connecting flange 302. Tube sheets are provided inside both the front-end header 2 and the rear-end header 3 to fix and support the heat exchange tubes 601. The liquid to be cooled enters from the front-end connecting pipe 201, passes through the front-end header 2 and enters the heat exchange tubes 601, then flows to the rear-end header 3 and flows out from the rear-end connecting pipe 301.

[0034] A first support leg 101 and a second support leg 102 are provided at the lower part of the cooler housing 1. The first support leg 101 and the second support leg 102 provide stable support for the cooler housing 1 to prevent overall tipping and improve the service life. The first support leg 101 is located on the left side of the second support leg 102 and is trapezoid-shaped. An inlet pipe 4 and an outlet pipe 5 are provided at the upper part of the cooler housing 1. Connecting components are provided on both the inlet pipe 4 and the outlet pipe 5, and the connecting components can be flanges. The inlet pipe 4 is located on the left side of the outlet pipe 5. A flow splitting component is provided at the lower part of the inlet pipe 4. The flow splitting component includes a fixed bracket 402 and a flow splitter 401. The fixed bracket 402 is fixedly connected to the lower surface of the inlet pipe 4, and the fixed bracket 402 is fixedly connected to the flow splitter 401. The upper part of the flow splitter 401 is a cone. When the cooling liquid enters from the inlet pipe 4 and encounters the flow splitter 401, the aggregated water flow is dispersed into a circumferential water flow. The dispersed water flow is not easy to directly impact the heat exchange tubes 601, improving the service life of the heat exchange tubes 601 and being convenient to use. The flow splitter 401 does not contact the inlet pipe 4 to avoid the flow splitter 401 blocking the inlet of the inlet pipe 4. The fixed bracket 402 is located above the heat exchange tubes 601 and does not contact them. An axial flow ring 6 and heat exchange tubes 601 are provided inside the cooler housing 1. The axial flow ring 6 plays a role in fixing and restricting the heat exchange tubes 601, and at the same time has evenly distributed gaps to ensure the normal circulation of the cooling liquid and good heat exchange effect. The length of the heat exchange tubes 601 is the same as the length of the cooler housing 1, increasing the contact time between the cooling liquid and the heat exchange tubes 601 and improving the cooling efficiency.

[0035] Working principle: The liquid to be cooled enters from the front-end connecting pipe 201, passes through the front-end tube sheet 2 and enters the heat exchange tube 601. The cooling liquid enters from the inflow pipe 4. After encountering the fluid distributor 401, the aggregated water flow is dispersed into a circumferential water flow. The dispersed water flow is not likely to directly impact the heat exchange tube 601, improving the service life of the heat exchange tube 601. It is convenient to use. The coolant contacts the heat exchange tube 601 to achieve the cooling function. The liquid after cooling flows out from the outflow pipe 5. The liquid to be cooled after being cooled flows to the rear-end tube sheet 3 and flows out from the rear-end connecting pipe 301.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
