[0055] Preferably,

[0056] Working process and principle:

[0057] The integrated multi-channel temperature-controlled flow oil cooler is divided into two main circuits, namely the cooling circuit and the oil supply circuit. The cooling circuit consists of a cooling oil pump 3, a cooling oil filter device 4, and a plate heat exchanger 5. After the circuit is opened, the oil flows from the cooling circuit oil inlet 131 at the bottom of the oil storage tank 1 to the suction chamber 132 of the cooling oil pump, is sucked in by the suction port 301 of the cooling oil pump, discharged from the oil outlet 302 of the cooling oil pump to the discharge chamber 133 of the cooling oil pump, passes through the transition oil chamber, enters the cooling oil filter inlet chamber 141, enters the cooling oil filter device 4 through several cooling oil filter inlet holes 401 on the cooling oil filter housing, and after filtration, is discharged from the adapter 17 connected to the cooling oil filter device 4 to the cooling oil filter outlet chamber 142, enters the plate heat exchanger inlet chamber 151 through the plate heat exchanger inlet port 501, is discharged from the plate heat exchanger outlet port 502 after cooling, and flows back into the oil storage tank 1 through the cooling circuit oil return hole 152.

[0058] The oil supply circuit consists of an oil supply pump 8, an oil supply filter device 9, an oil supply temperature sensor 11, a flow valve 10, a first oil supply port 12, a second oil supply port 13, etc. After the circuit is opened, the oil flows from the oil supply circuit oil inlet 181 at the bottom of the oil storage tank 1 to the suction chamber 182 of the oil supply pump, is sucked in by the suction port 801 of the oil supply pump, discharged from the oil outlet 802 of the oil supply pump to the discharge chamber 183 of the oil supply pump, passes through the transition oil chamber, enters the oil supply filter inlet chamber 191, enters the oil supply filter device 9 through several oil supply filter inlet holes 901 on the oil supply filter housing, and after filtration, is discharged from the adapter 17 connected to the oil supply filter device 9 to the oil supply filter outlet chamber and enters the oil supply circuit oil passage 1101, where there is an oil supply temperature sensor 11;

[0059] The oil supply oil passage has two oil supply ports, separated by a flow valve 10 in the middle. When only one-way oil supply is required, the pipeline is connected to the first oil supply port 12, and the flow valve 10 is closed, and no oil flows out of the second oil supply port 13; when two-way oil supply is required, the pipeline is connected to the first oil supply port 12 and the second oil supply port 13, the flow valve 10 is opened, and the flow distribution of the two oil supply ports is adjusted according to the set flow value.

[0060] After the controller 2 receives the signals of the set oil temperature, flow rate, and cooling water flow rate and temperature from the upper computer, if the set temperature is higher than the oil temperature detected by the oil storage tank temperature sensor 15, the cooling circuit is started, and heat exchange is carried out with the cooling water in the plate heat exchanger 5. The cooled oil flows back to the oil storage tank 1, and such continuous internal circulation cools the oil and filters the oil at the same time. The flow rate of the cooling circuit is calculated by the controller 2 according to the temperature detected by the oil storage temperature sensor, as well as the set cooling water flow rate and temperature. If the set temperature is lower than the oil temperature detected by the oil storage temperature sensor, the PTC heater 14 is turned on to heat the oil.

[0061] After reaching the set oil temperature, the controller 2 controls the opening of the oil supply circuit and pumps oil at a set flow rate. During operation, the controller 2 controls the opening and closing of the cooling oil circuit and the PTC heater 14 by monitoring the difference between the oil supply temperature sensor 11 and the set outlet oil temperature. The flow rate of the cooling circuit and the power of the heater are calculated by the controller 2. After the oil fluid completes the external circulation, it flows back into the storage tank 1 through the oil return nozzle 16 on the storage tank 1.

[0062] Advantages:

[0063] 1. Different from existing oil coolers that use industrial-grade components, the present utility model uses automotive-grade parts with small volume and high compactness - oil pump, oil filter, plate heat exchanger 5, controller 2, temperature sensor, and PTC heater 14;

[0064] 2. Each component is directly integrally installed on the storage tank 1, with simple installation, few components, simplified connecting pipelines between components, making the structure very compact and highly reliable;

[0065] 3. The oil cooler of the present utility model is very small in volume and light in weight, with strong portability and mobility, and can freely change the application scenario;

[0066] 4. Two sets of oil pump and oil filter systems, one of which is connected to the plate heat exchanger 5 to continuously carry out internal circulation of the oil, cool the oil through the external water circuit in the plate heat exchanger, and adjust the flow rate of the internal circulation with the controller 2 according to the oil temperature feedback by the temperature sensor to quickly reach the set temperature value; the other is connected to the oil supply pipeline, and the controller 2 adjusts the oil pump to supply oil externally at a set flow rate.

[0067] 5. By means of the flow valve 10, multiple oil supplies are formed, and the number of oil supply circuits is more flexible and variable.

[0068] 6. The present utility model only needs to be externally connected to a circulating water circuit for cooling, does not require an air conditioning system, and has strong energy-saving performance.

[0069] The above is only the preferred implementation manner of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
