Embodiment 1

[0052] as attached figure 1 And attached figure 2 As shown, the automobile heat dissipation performance testing system of the present invention includes a wind tunnel, and the wind tunnel includes an air inlet tube 1 and an air outlet tube 31 docked on the left and right sides, and an air inlet tube 1 and an air outlet tube 31 are arranged between the air inlet tube 1 and the air outlet tube 31 for use with water-cooled heat dissipation. The water inlet pipe 17 and the water outlet pipe 16 connected to the part 13 and the air inlet pipe 11 and the air outlet pipe 9 for connecting with the air-cooled heat sink 6 are installed in the water inlet pipe 17, the water outlet pipe 16, the air inlet pipe 11 and the air outlet pipe 9. Temperature detector, the air inlet tube 1 is divided into an air inlet end with a concentrating effect and an air outlet end with a flow stabilization effect; the air outlet tube 31 is an outlet tube with a flow stabilization effect; the outlet of the a...

Embodiment 2

[0062] as attached Figure 4 As shown, this embodiment is a further improvement on the basis of Embodiment 1. The difference between this embodiment and Embodiment 1 is: the air outlet end of the air inlet cylinder 1 is sealed but connected with a diffusion transition section 36 with a diffusion angle of 8°. The air inlet end of the air outlet tube 31 is sealed butted with a convergent transition section 37 with a convergence angle of 15°, the large mouth end of the diffuse transition section 36 and the large mouth end of the convergent transition section 37 are docked left and right, and the air-cooled heat sink 6 and the water-cooled heat sink 13 is sequentially installed between the diffusion transition section 36 and the convergence transition section 37 from left to right.

[0063] Through the cooperation of the diffusion transition section 36 and the convergence transition section 37, performance tests on various types of radiators and intercoolers can be realized.
