Embodiment 1
[0071] see Figure 1-Figure 2 , the high-precision oil cooler of the present invention includes a refrigeration system and a circulating oil circuit system, wherein,
[0072] The refrigeration system includes a main flow system and a side branch flow system, wherein,
[0073] The main flow system includes an inverter compressor 1, a condenser 2, a fan 3, a filter 4, an electronic expansion valve 5, and an evaporator 6, wherein the suction end of the inverter compressor 1 is connected to the evaporator 6 The outlet port is connected, and the exhaust port is connected with the inlet port of the condenser 2; the fan 3 is arranged on the condenser 2, and the outlet port of the condenser 2 is connected with the inlet port of the filter 4; The outlet end of the filter 4 communicates with the inlet end of the electronic expansion valve 5, and the outlet end of the electronic expansion valve 5 communicates with the inlet end of the evaporator 6;
[0074] The bypass flow system inclu...
Embodiment 2
[0116] see image 3 The difference between this embodiment and Embodiment 1 is that the control method of the high-precision oil cooler of the present invention is applied in the inlet oil temperature control mode, the frequency control of the inverter compressor 1 and the opening of the bypass flow regulating valve 8 Degree control is carried out according to the following steps (for details, see image 3 ):
[0117] (T1) The oil pump 13 is turned on, and the inlet oil temperature T is detected -进口 , set the inlet oil temperature T _set-进口 , when the inlet oil temperature reaches the set target temperature, namely T -进口 =T _set-进口 ; then keep the current state;
[0118] (T2) When the inlet oil temperature is lower than the set target temperature, that is, T -进口 _set-进口 ; If the variable frequency compressor 1 is not turned on, keep the current state;
[0119] (T3) When the inlet oil temperature is lower than the set target temperature, that is, T -进口 _set-进口 ;
[012...
Embodiment 3
[0128] The difference between this embodiment and Embodiment 1 is that in step (4) of the control method of the high-precision oil cooler of the present invention, the maximum opening degree E of the bypass flow regulating valve 8 is fully opened max (that is, 500B) is used as the inverter compressor 1 frequency 0Hz control, and 0B when the bypass flow regulating valve 8 is fully closed is used as F min (i.e. 20HZ) control; set E max (ie 500B) According to the flow curve of the bypass flow regulating valve 8, the opening is determined according to the equal flow; 0-E max Among other opening parameters with inverter compressor 1F min The frequency parameters between -0Hz correspond in turn; as shown in the following table:
[0129]
[0130] The remaining steps are completed with reference to Example 1.
[0131] This embodiment aims at bypassing the flow regulating valve 8 with a non-linear flow curve, so that its change is close to linear, which is more conducive to the s...
