The invention discloses an economic and efficient opening direct current type ice wind tunnel, which comprises an air inlet, a power section, a diffusion section, a stabilization section, an ice and snow particle generating section and a test section in sequential connection, wherein a liquid nitrogen spray head and a pneumatic spray head are arranged in the ice and snow particle generating section, the nitrogen spray head is connected with a liquid nitrogen source through a liquid nitrogen pipeline for forming a liquid nitrogen refrigeration system, and the pneumatic spray head is connected with a pressure air source and a pressure water source through a mixing pipeline for forming a water particle generating system; a fan is arranged in the power section. The economic and efficient opening direct current type ice wind tunnel has the advantages that the process is simple, the single-time test cost is low, the test efficiency is high, and the manufacturing cost is low. The defects that the large-scale ice wind tunnel needs to be provided with large-scale refrigeration deicing equipment, the cost is high, and in addition, the test period is long are overcome. The requirements of ordinary ice and snow particle fluid teaching and scientific research and experiments can also be met.
