A test device for simulating gas pressure loss, comprising: the air inlet pipe is connected with the air outlet pipe;

the resistance unit is arranged in the box body, round holes are respectively arranged on the air inlet pipe and the air outlet pipe, and the round holes are respectively connected with two pipes on the differential pressure gauge.

Furthermore, the resistance units are reinforcing ribs which are uniformly distributed on the bottom surface and the side surface in the box body.

Furthermore, a damping structural part is arranged between the reinforcing ribs.

Further, the damping structure is asbestos mesh, sound-absorbing cotton, filter cotton or sponge.

Further, the damping structure is installed between the reinforcing ribs through sealing cement.

Furthermore, the top of the box body is a detachable upper cover plate.

Furthermore, an air duct is arranged between the mouth of the air inlet pipe and the mouth of the air outlet pipe, and the length of the air duct is 4-20cm.

Further, the air blower is an air conditioner air blower or an air cooling battery pack air blower.

The utility model discloses technical scheme has following advantage:

1. the pressure loss of an air conditioner and a cooling system can be simulated at the initial development stage, a noise test can be carried out by matching with the air blower, and the noise risk can be predicted. So the utility model discloses there is better correspondence to vehicle air conditioner case and forced air cooling battery package noise test.

2. The utility model discloses it is small, can adapt to whole car test environment.

3. The utility model discloses the installation is simple, and used material still has characteristics with low costs, that the quality is light for cast aluminium.

4. The utility model discloses except being applicable to vehicle air conditioner case air-blower, the forced air cooling battery package air-blower is outside, still can be applicable to the loss of pressure simulation among other air-blower service environment.

5. The utility model discloses no mechanical motion part can not produce extra noise in the experiment, can not disturb air-blower noise and fluid noise production.
