Technical field
The present invention relates to a kind of flow mixing device, particularly a kind of gas-liquid two-phase flow mixing device.
Background technology
The temperature and pressure of evaporator outlet medium is the important parameter of reactive evaporation device performance, the refrigerant of traditional evaporimeter flow through into single current through or flow path less, and each flow path is longer, in heat transfer process, refrigerant can be thoroughly mixed to form single-phase superheated vapor to evaporimeter end, therefore can directly detect outlet medium temperature and pressure at evaporimeter end.
But the MEDIA FLOW of existing evaporimeter is through more, and each flow path is shorter, in the not high situation of the degree of superheat, evaporimeter end refrigerant can not evaporate completely, thereby there will be the evaporimeter outflow end gas-liquid two-phase refrigerant can not well-mixed problem, and the gaseous medium temperature that each flow path collects be inconsistent.
The gas-liquid two-phase refrigerant flowing out due to evaporimeter end can not fully mix, respectively flow through flow out MEDIA FLOW temperature inconsistent, in the time of test point position, still there is strong heat exchanging process in refrigerant, system can not reach stable state, and therefore the temperature of existing evaporator outlet medium can not accurately be measured; Further, the refrigerant state of existing evaporimeter outflow end is invisible, and the refrigerant state of outflow end has decisive role to the setting assessment of systematic function; Therefore need a kind of device that can accurately test existing evaporator outlet medium temperature and pressure and observation evaporator outlet refrigerant state.
Summary of the invention
In view of this, the object of this invention is to provide a kind of parallel-flow evaporator test flow mixing device, the problem that can not accurately be measured to solve the temperature of existing evaporator outlet medium.
Parallel-flow evaporator test flow mixing device of the present invention, comprise body, with the sealed at both ends pipe joint being connected of body, be arranged at the copper wire suede obturator in body and be covered in body and pipe joint outside heat-insulation layer.
Further, described body is the transparent tube body of being made up of acrylic material, and described pipe joint is the transparent pipe joint of being made up of acrylic material, on described heat-insulation layer, is provided with watch window.
Further, described copper wire suede obturator is more than or equal to by joint length the copper wire that 200mm, cross section full-size be less than or equal to 1.0mm and forms, and the density of described copper wire suede obturator is 0.5～1.0g/cm
3.
