By arranging that the outer side of the tube bundle is covered with a radiator casing, the leakage of the air fluid is reduced, and the air fluid is guided, so that the air fluid can flow from the air inlet to the air outlet. By setting the axial direction of the inlet water pipe, the three-dimensional deformation pipe and the outlet water pipe to be the same, the fluid can form a turbulent flow in the pipe body, which replaces the lateral scouring structure of the previous tubular radiator design, and the resistance coefficient of lateral scouring is far greater. Due to the turbulent flow, the flow resistance of the fluid is greatly reduced. By arranging the upper end face of the radiator shell away from one end of the inlet water pipe, an air inlet is opened, so that a pure reverse flow can be formed between the two fluids in the radiator. At the same time, the heat transfer coefficient of the heat exchange module is larger than that of other heat exchange equipment, so when the heat transfer power is the same, compared with other heat exchange equipment, it can effectively save 15 %-50% of the heat exchange area, that is, 15%-50% of equipment manufacturing materials can be saved.

By adopting the above technical scheme, it is used to ensure that there is a certain interval between the tube bundles, and the main purpose is to achieve the effect of multi-faceted air inlet and outlet, so as to achieve the effect of reducing the local resistance of the inlet and outlet.

The utility model is further provided that: hollow end caps are installed at both ends of the tube bundles, and the two ends of the tube bundles are respectively connected with the inlet water pipe and the outlet water pipe through the end caps, and the end caps A sealing welding plate is arranged between the cover and the tube bundle to seal the end cover, and the end cover is connected with the radiator housing.

By adopting the above technical solution, the two ends of the tube bundle are respectively connected with the inlet water pipe and the outlet water pipe through the end caps, so that the two ends of the three-dimensional deformation pipe do not need to be bent and converge to the inlet water pipe and the outlet water pipe respectively, reducing the flow caused by the lateral scouring of the fluid. resistance, making the fluid flow more smoothly.

The utility model is further configured as follows: the air inlet is provided with a fan installation port, and the fan installation port is provided with a fan whose air outlet is arranged vertically downward.

By adopting the above technical solution, the fan installed vertically downward is installed at the fan installation port, which accelerates the air fluid at the air inlet, so that more air fluid can enter from the air inlet, and plays a guiding role for the air fluid.

To sum up, the utility model has the following beneficial effects:

1. By setting the three-dimensional deformation tube into a twisted elliptical tube structure, when the three-dimensional deformation tubes are arranged side by side, the positions of the three-dimensional deformation tubes with the same pitch can support each other, thereby forming a self-supporting structure, effectively reducing equipment operation. When the vibration is generated, the anti-vibration capability of the tube bundle is enhanced, so that there is no need to set up a separate anti-vibration structure, which saves materials and reduces economic losses; at the same time, the tube bundle is hollowed out to facilitate the passage of air and fluid;

2. By setting the axial direction of the inlet water pipe, the three-dimensional deformation pipe and the outlet water pipe to be the same, the fluid can form a turbulent flow in the pipe body, replacing the horizontal scouring structure of the previous tubular radiator design, and the resistance of horizontal scouring The coefficient is much larger than the turbulent flow, which greatly reduces the flow resistance of the fluid;

3. By setting the upper end face of the radiator shell away from the inlet water pipe, an air inlet is opened, and the end of the radiator shell close to the inlet water pipe is provided with an air outlet, so that a pure reverse flow can be formed between the two fluids in the radiator , compared with the interlaced flow of the previous tubular radiator, the heat transfer temperature difference is effectively increased, thereby increasing the heat exchange power of the equipment; at the same time, the heat transfer coefficient of the heat exchange module is larger than other heat exchange equipment, so When the heat transfer power is the same, compared with other heat exchange equipment, 15%-50% of the heat exchange area can be effectively saved, that is, 15%-50% of equipment manufacturing materials can be saved.
