Abstract
The utility model discloses an inter cooler for a motor stand test, which comprises a heat exchanger and a temperature control system for controlling the heat exchanger. The heat exchanger is an inter-cooling and heat exchanger with an air inlet and an air outlet. The inter-cooler is characterized in that a circulating cooling water tank is further arranged outside the heat exchanger; and a water inlet and a water outlet for inputting cooling water are formed on the water tank. The inter cooling system can satisfy the requirements for high air intake volume and high cooling strength required for the motor stand test, thereby achieving the automatic accurate control to air intake temperature after inter-cooling.
Description
Technical field
The utility model relates to a kind of cooling unit, relates in particular to a kind of motor car engine stand test usefulness, engine charge is cooled off the ICS intercooler system of control.
Background technique
Refrigeration technique belongs to newer technology in the motor car engine turbosupercharging, and the difficulty of enforcement is bigger.On test-bed, to carry out the engine development test in order satisfying, after need cooling off the fresh air after the turbosupercharging, to enter in the cylinder again and burn.Intake temperature is one of parameter that influences engine performance.In the part stand test process, need control accurately Engine Inlet Temperature, original Vehicular air is difficult to satisfy the high air inflow of petrol engine, the requirement of high intensity of cooling to air cooled ICS intercooler system, also can't realize automatic control.
Summary of the invention
The technical problems to be solved in the utility model is to remedy above-mentioned the deficiencies in the prior art, and a kind of satisfy high air inflow, high intensity of cooling are provided, and realizes the stand test ICS intercooler system of control automatically.
Technical problem of the present utility model is solved by the following technical programs: a kind of engine rig test ICS intercooler system, the temperature control system that comprises heat exchanger and the described heat exchanger of control, described heat exchanger is the middle cold and warm exchanger with suction port and air outlet, it is characterized in that: also be provided with encirclement formula recirculated cooling water case in described heat exchanger outside, have the water intake and the water outlet of input cooling water on the described water tank.
Technical problem of the present utility model is further solved by following technological scheme:
Above-mentioned engine rig test ICS intercooler system, described temperature control system comprises the PID control unit.
Above-mentioned engine rig test ICS intercooler system can also comprise the flow control device that is arranged on described water intake.Described flow control device is the electronics Proportional valve.
Above-mentioned engine rig test ICS intercooler system, described recirculated cooling water case are encirclement formula recirculated cooling water case.
The utility model beneficial effect compared with prior art is: because the utility model adopts circulating water cooling system to replace the air-air cooling system, improve intensity of cooling, and then satisfied the requirement of needed high air inflow of turbosupercharged engine stand test and high intensity of cooling.The utility model adopts the PID control unit to come the mode of control ratio valve to regulate the cooling inflow, has realized the accurately control automatically of the cold back of centering intake temperature.
Description of drawings
Fig. 1 is that heat exchanger is analysed and observe organigram in the utility model ICS intercooler system;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the plan view of Fig. 1;
Fig. 4 is a work system schematic representation of the present utility model.
Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further details below by concrete mode of execution.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, engine rig test ICS intercooler system of the present utility model comprises existing middle cold and warm exchanger 5 and temperature control unit 8, and middle cold and warm exchanger 5 is provided with suction port 4 and air outlet 3.Outside middle cold and warm exchanger 5, also be provided with encirclement formula recirculated cooling water case 6, the water intake 1 and the water outlet 2 of input cooling water arranged on the water tank 6, electronics Proportional valve 7 is installed at water intake 1.
As shown in Figure 4, work system of the present utility model, temperature control unit is electrically connected electronics Proportional valve 7.The open type cooling water road is to be embedded in the complete circulation waterway system of test room, and electronics Proportional valve 7 is installed in feed-water end, and the backwater end does not have pressure.Commercially available electronics Proportional valve 7 is by 8 controls of commercially available PID (being Proportinal-Integral-Derivative, proportion integration differentiation) control unit.By writing PID control unit software, for adjusting object, the flow of cooling water is controlled according to the actual intake temperature of measuring in the system.Software section is divided into manually and automatic two kinds of control modes.Under the situation of the enough supplies that guarantee water, can accurately control temperature.
The utility model is at threst stand, according to the mounting point difference of different turbosupercharged engines, and can this system of flexible arrangement.Tank shell and automobile-used middle cold and warm exchanger are connected to the heat exchange space of a sealing by welding technique.Control intake temperature after the engine turbine supercharging accurately by using former intercooler, can reaching through the car load coupling.By certain modification, to the encirclement formula design of its peripheral structure, reserved enough current by the space, make its function that reaches heat exchanger, and the final type of cooling changes to the cooling of circulating water to air.
Present embodiment replaces the cooling of air-air with circulating water cooling system, improved intensity of cooling; Use the mode control ratio valve of PID to realize accurately controlling automatically of the cold back of centering intake temperature; This constituent installs some device additional on the basis of original automobile-used constituent, fully use the original environmental resources and the software resource of engine pedestal control system; This ICS intercooler system is simple in structure, and easy accessibility is suitable for enforcement.
