[0024] Embodiment 1:

[0025] This embodiment provides an oil cooler with temperature regulation, such as Figures 1 to 5As shown, it includes: a cooler core 1, which is a rectangular parallelepiped structure, and the cooler core 1 includes a core shell 11 and a core cavity; the core shell 11 includes a core oil inlet hole 111, a core bypass oil inlet hole 112 and a core oil outlet hole 113, the core oil inlet hole 111 and the core bypass oil inlet hole 112 are located at the bottom edge of the core shell 11, and the core oil outlet hole 113 is located at the top edge of the core shell 11; the core cavity includes a core oil circuit and a core bypass oil circuit, the top end of the core oil circuit is connected to the core oil outlet hole 113, and the bottom end is connected to the core oil inlet hole 111, the bottom end of the core bypass oil circuit is connected to the core bypass oil inlet hole 112, and the top end of the core bypass oil circuit is connected in parallel to the top end of the core oil circuit; a cooler base 2, which is a cabin structure, and the cooler base 2 includes a base shell 21, a base cavity 22, a bottom The base shell 21 includes a thermostat through hole 211 and a partition 212; the base shell 21 includes a base oil inlet 213 and a base oil outlet 214 on the side close to the base cavity 22; the base shell 21 includes a base bypass oil outlet 215 on the side close to the base bypass cavity 23; the partition 212 is located between the base cavity 22 and the base bypass cavity 23; the base oil inlet 213 is located on the bottom surface of the base shell 21, the base oil outlet 214 and the base bypass oil outlet 215 are located on the top surface of the base shell 21, and the thermostat through hole 211 is located on the partition 212; wherein, the core oil inlet is connected to the base oil outlet 214, and the core bypass oil inlet is connected to the base bypass oil outlet 215; the core bypass oil circuit is arranged perpendicular to the ground.

[0026] Specifically, in existing engines, especially marine diesel engines, one is that bubbles are easily mixed into the engine oil, such as Figure 6 As shown, the oil accumulates at the corner of the pipe, causing air blockage and being unable to be discharged. Secondly, the prior art cannot control the cooled oil to a suitable temperature, and the oil is cooled indiscriminately regardless of its temperature.

[0027] In order to solve the problems existing in the background technology, the oil circuit of this embodiment adopts a structure that is through from bottom to top, including the thermostat 24 being a tubular structure open at the top and bottom, and the core bypass oil circuit being arranged vertically to the ground. Since the bubbles in the engine oil are light in weight, they will only enter the base bypass cavity 23 through the thermostat 24 and be discharged through the vertical bypass oil circuit to avoid air blockage. The thermostat 24 is preferably a paraffin core thermostat, because Figure 3As shown, the engine oil enters the thermostat 24 from the bottom, and the thermosensitive paraffin core can change the height of the thermostat 24 body according to the temperature of the engine oil, thereby changing the diversion ratio between the base cavity 22 and the base bypass cavity 23. The engine oil entering the base bypass cavity 23 enters the cooler core 1 through the core bypass oil path for heat dissipation. Since the core bypass oil path is arranged perpendicular to the ground, the contact area and contact time between the core bypass oil path and the coolant are smaller than the core oil path, and the engine oil temperature passing through the core bypass oil path is higher.

[0028] Among them, "high", "top", etc. refer to the vertically upward direction; "low", "bottom", etc. refer to the vertically downward direction.
