Abstract
The utility model discloses the heat exchange mechanisms on a kind of hydrodynamic retarder testing apparatus, it comprises a heat exchanger and a water tank, and heat exchanger provides refrigerant for hydrodynamic retarder to be tested, and the water in water tank is the refrigerant cooling in heat exchanger.The utility model can provide refrigerant for hydrodynamic retarder, and the refrigerant passage in hydrodynamic retarder can not be made to block.
Description
Technical field
The utility model relates to the heat exchange mechanisms on a kind of hydrodynamic retarder testing apparatus.
Background technique
Hydrodynamic retarder is a kind of auxiliary brake device for automobile, be mainly used in motorbus, urban public traffic vehicles, heavy truck and military vehicle, hydrodynamic retarder comprises housing, housing have shoe cream room and working oil chamber, impeller of rotor and stator impeller is provided with in working oil chamber, the output shaft of impeller of rotor and automotive transmission case is fixed together, and in motion, impeller of rotor also can rotate automobile.During hydrodynamic retarder work, pressurized air enters shoe cream room, oil pressure in shoe cream room is entered the cavity between stator impeller for hydrodynamic retarder and impeller of rotor, when hydrodynamic retarder is started working, impeller of rotor drives fluid to rotate about the axis, simultaneously, fluid moves along the direction blade of impeller of rotor and gets rid of to stator impeller, the blade of stator impeller produces reaction force to fluid, fluid outflow stator impeller goes back to impact rotor impeller again, so just form the resisting moment to impeller of rotor, impeller of rotor is made to produce braking torque, thus the decelerating effect realized vehicle.
A kind of hydrodynamic retarder testing apparatus is had to may be used for carrying out testing property to hydrodynamic retarder at present, when testing hydrodynamic retarder, hydrodynamic retarder needs normal work, this needs to be cooled by refrigerant with regard to making the hydraulic oil in hydrodynamic retarder, at present generally direct using external water source as refrigerant, and general containing more impurity in external water source, easy like this refrigerant passage in hydrodynamic retarder is blocked, hydrodynamic retarder cannot normally be worked.
Model utility content
Technical problem to be solved in the utility model is, provides the heat exchange mechanisms on a kind of hydrodynamic retarder testing apparatus, and it can provide refrigerant for hydrodynamic retarder, and the refrigerant passage in hydrodynamic retarder can not be made to block.
For solving the problems of the technologies described above, heat exchange mechanisms on the hydrodynamic retarder testing apparatus that the utility model provides, it comprises a heat exchanger and a water tank, described heat exchanger has the first liquid entering hole, first liquid outlet, first refrigerant import and the first refrigerant exit, described water tank has the second liquid entering hole, second liquid outlet, water intake and drain opening, hydrodynamic retarder to be tested has the second refrigerant import and the second refrigerant exit, described first liquid outlet is connected by pipeline with the second refrigerant import, described first liquid entering hole is connected by pipeline with the second refrigerant exit, pipeline between first liquid entering hole and the second refrigerant exit is provided with the first electric water pump, described first refrigerant exit is connected by pipeline with the second liquid entering hole, pipeline between first refrigerant exit and the second liquid entering hole is provided with the second electric water pump, described first refrigerant import is connected by pipeline with the second liquid outlet, water intake connects external water source.
After adopting above structure, the utility model compared with prior art, has following advantage:
The utility model in use, heat exchanger provides refrigerant for hydrodynamic retarder to be tested, and the water in water tank is the refrigerant cooling in heat exchanger, like this, constantly carry out the circulation of refrigerant between heat exchanger and hydrodynamic retarder to be tested, and do not need external water source, avoid external water source and make to be mixed in refrigerant impurity, thus avoid the refrigerant passage in hydrodynamic retarder to be tested to block, thus ensure that the normal use of hydrodynamic retarder.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, heat exchange mechanisms on the utility model hydrodynamic retarder testing apparatus comprises heat exchanger 1 and a water tank 2, described heat exchanger 1 has the first liquid entering hole 101, first liquid outlet 102, first refrigerant import 103 and the first refrigerant exit 104, described water tank 2 has the second liquid entering hole 201, second liquid outlet 202, water intake 203 and drain opening 204, hydrodynamic retarder 3 to be tested has the second refrigerant import 301 and the second refrigerant exit 302, described first liquid outlet 102 is connected by pipeline with the second refrigerant import 301, described first liquid entering hole 101 is connected by pipeline with the second refrigerant exit 302, pipeline between first liquid entering hole 101 and the second refrigerant exit 302 is provided with the first electric water pump 4, described first refrigerant exit 104 is connected by pipeline with the second liquid entering hole 201, pipeline between first refrigerant exit 104 and the second liquid entering hole 201 is provided with the second electric water pump 5, described first refrigerant import 103 is connected by pipeline with the second liquid outlet 202, water intake 203 connects external water source.
The utility model in use, first electric water pump 4 and the second electric water pump 5 work, in refrigerant inflow heat exchanger 1 in hydrodynamic retarder 3 to be tested, be back in hydrodynamic retarder 3 to be tested after being lowered the temperature by heat exchanger 1, and for refrigerant cooling water provided by water tank 2, in the continuous inflow heat exchanger 1 of water of water tank 2, then the heat of the refrigerant in absorption heat-exchange device 1 is back in water tank 2, and constantly access external water source by water intake 203, constantly discharge water by drain opening 204 in water tank 2, always lower to ensure the coolant-temperature gage in water tank 2.
Below only apply preferably example with regard to the utility model and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes done in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
