Description
Technical field
It the utility model is related to a kind of cooling system of dynamometer machine in engine test table.
Background technology
Include the equipment such as engine, electric eddy current dynamometer, fuel consumption meter in automotive engine test bench.In electric eddy current dynamometer
During operation, produce vortex flow using electromagnetic induction and form braking action, and the energy conversion that engine shaft is exported
For heat energy, heat is then taken away by cooling water.Existing cooling device mainly by：Cooling water pipe, cement is used under earth's surface
The reservoir chamber being built into, and the cooling tower positioned at earth's surface.Due to the poor and located underground confined space of cement heat conductivility,
Cause natural cooling effect poor.External cooling tower is needed to operate carry out forced heat radiation, its energy for a long time in the form of high-power
It is big to consume very high and cooling tower mechanical loss.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of cooling effectiveness is high, energy consumption is low, the mechanical damage of cooling tower
Consume small new electric eddy current dynamometer cooling system.
To solve the above problems, the technical solution adopted in the utility model includes the cooling water that one end is connected with dynamometer machine
Pipe, the cooling water pipe are made up of water inlet pipe and outlet pipe, are respectively connected with water pump on the water inlet pipe, outlet pipe, its feature exists
In：The water inlet pipe, outlet pipe other end respectively be placed in outdoor enter pond, discharge bay is connected, it is described enter pond, water outlet
Pond is made up of metal material and side is connected by first passage, second channel, in the first passage, second channel respectively
Be provided with aperture regulation valve, it is described enter pond, discharge bay other end connection cooling tower.
Described new electric eddy current dynamometer cooling system, it is characterised in that：The water inlet pipe and the junction for entering pond
Provided with temperature sensor.
Described new electric eddy current dynamometer cooling system, it is characterised in that：The water inlet of the water inlet pipe is provided with filter
Net.
New electric eddy current dynamometer cooling system advantage of the present utility model is as follows：
When the water temperature that temperature sensor measures is higher than 30 DEG C, cooling tower is started working, first passage, second channel valve
Close.In the cooling tower course of work, when the water temperature that temperature sensor measures is close to environment temperature and when tend towards stability, cooling
Tower is stopped, and the aperture regulation valve in first passage, second channel is opened with different degree.And so on circulate, can
Natural heat dissipation is maximized, time and frequency that cooling tower is opened is reduced, reduces the consumption of electricity.And cooling tower can be intermittent
Work, be advantageous to increase the service life of cooling tower.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is systematic schematic diagram of the present utility model；
Fig. 2 is pool construction schematic diagram of the present utility model.
Embodiment
As shown in Figure 1-2, new electric eddy current dynamometer cooling system of the present utility model, including one end connect with dynamometer machine 1
The cooling water pipe 2 connect, the cooling water pipe 2 are made up of water inlet pipe 3 and outlet pipe 4, the water inlet pipe 3 and outlet pipe 4 respectively with
Port corresponding to dynamometer machine 1 connects.Water pump 5 is respectively connected with the water inlet pipe 3, outlet pipe 4.The water inlet pipe 3, outlet pipe 4
Other end respectively be placed in outdoor enter pond 6, discharge bay 7 is connected, it is described enter pond 6, discharge bay 7 by metal material system
Into and side both ends connected by first passage 8, second channel 9, be respectively arranged with the first passage 8, second channel 9
Aperture regulation valve 11, it is described enter pond 6, the other end of discharge bay 7 pass through pipeline connect cooling tower 10.
Further, the water inlet pipe 3 is provided with temperature sensor 12, the temperature sensor with entering the junction in pond 6
12 are used to detect the water temperature in pond 6.The water inlet of the water inlet pipe 3 is provided with filter screen 13, and the filter screen 13 is used to filter
Impurity in water.
Operation principle：
1st, when sensor temperature is less than 30 DEG C, cooling tower is without work, the first passage, second channel
Interior aperture regulation valve is in different apertures, to reach maximum natural cooling effect.
2nd, when the water temperature that sensor measures is higher than 30 DEG C, because cooling water now is reached into the water temperature upper limit, in order to anti-
Only inflow temperature is too high causes dynamometer machine to be damaged, therefore the aperture regulation valve in the first passage, second channel is all closed,
Cooling tower, which is started working, carries out forced heat radiation.The temperature of water after cooling tower radiates is flowed into pond close to normal temperature,
The water temperature in pond is promoted to drop to close to environment temperature as early as possible.When the water temperature that temperature sensor measures close to environment temperature and becomes
When stablizing, cooling tower is stopped, and the aperture regulation valve in the first passage, second channel is with different degree
Open.And so on circulate, maximizing natural heat dissipation, reduce time and frequency that cooling tower is opened, reduce the consumption of electricity.
And cooling tower, with intermittent work, can be advantageous to increase the service life of cooling tower.
In such scheme, designed by the aperture regulation valve in first passage, second channel, its effect is as follows：
1. by the different degrees of unlatching of the aperture regulation valve in first passage, second channel, realize into pond with going out
The abundant heat transfer of hot and cold water in pond come make natural heat dissipation amount maximize；
2. by the different degrees of unlatching of the aperture regulation valve in first passage, second channel, promote into pond with going out
Hot and cold water in pond produces certain convective motion and carrys out scattering and disappearing for accelerated heat；
3. by the different degrees of unlatching of the aperture regulation valve in first passage, second channel, hot water and water butt are allowed
Metal shell contact area maximize increase radiating；
4. by the aperture regulation valve in first passage, second channel, ensureing that temperature is Celsius less than 30 at oral siphon
In the case of degree, shorten time and the frequency of cooling tower work as much as possible, thus save electric energy.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
All any modification, equivalent and improvement made within new spirit and principle etc., are all contained in protection of the present utility model
Within the scope of.
