Technical field
The present invention relates to automotive environment modelling technique field, more particularly to a kind of to be used for automotive environment wind1 tunnel laboratory
Removable environmental test chamber.
Background technology
Automotive environment experimental cabin is environmental wind tunnel laboratory important component part.When low-temperature test is carried out, in order to shorten
Test time, first whole test vehicle is put into into automotive environment experimental cabin carries out precooling, when demanded, then by car
By hothouse, finally move in wind tunnel test cabin, carry out wind tunnel test.
The energy consumption of environmental wind tunnel laboratory can be reduced using automotive environment experimental cabin.At present, automotive environment experimental cabin
It is portable that design can be divided into fixed and air cushion from structure.What is presented in Fig. 9 is fixed type automobile environmental test chamber.Figure 10
Middle presentation is air-cushion moving formula automotive environment experimental cabin.For air-cushion moving formula automotive environment experimental cabin, due under it
With mobile air cushion, so ground is higher than outside ground in automotive environment experimental cabin, so, instruction carriage is needed by oblique in portion
Ramp passes in and out automotive environment experimental cabin.Due to the overall space of automotive environment experimental cabin it is compact, and in order to not change preparation
The temperature of good instruction carriage, instruction carriage can not start, it is therefore desirable to instruction carriage is pushed into release automotive environment experimental cabin by manpower,
Instruction carriage is caused to pass in and out very inconvenient during automotive environment experimental cabin.Further, since using air-cushion type move mode, automotive environment examination
The running fix low precision of hatch checking, increased the difficulty docked with hothouse；It is the warm and humid control system of automotive environment experimental cabin, new
Wind system and tail gas discharge system are integrated in the top that automotive environment tests cabin, cause the weight of whole automotive environment experimental cabin
Larger, its movement gets up also relatively elaborate.In addition, using existing fixed type automobile environmental test chamber or air-cushion moving formula automobile
Environmental test chamber, arranges hothouse between environmental test chamber and automobile wind tunnel test cabin, so causes whole environmental wind tunnel
Laboratory takes larger construction space, and the operating cost of environmental wind tunnel is also higher.
