A conventional circular oil dam is shown in dashed lines in fig. 3. As will be appreciated by those skilled in the art: on the premise of a certain pump power, if the heat exchange efficiency is to be improved, the flow resistance of the fluid channel needs to be reduced. For a conventional circular oil nozzle, increasing the radius of the circular oil nozzle can achieve the effect of reducing the flow resistance of the fluid channel, but due to the increase of the radius of the circular oil nozzle, the oil nozzle will occupy more workpieces, and accordingly, the space for arranging the fins will be reduced, thereby causing the heat exchange amount of the fins to be reduced. Therefore, for the conventional circular oil nozzle, the heat exchange efficiency cannot be improved by increasing the area of the oil nozzle to reduce the flow resistance. Referring again to fig. 5, the first oil hole 1111 according to an embodiment of the present invention has a horizontal cross section of a first irregular shape, and with respect to a circular oil hole, the area of the first irregular shape extends in the direction of the long diagonal L, and does not significantly extend in the direction of the short diagonal S, thus not occupying the space where the fins are disposed, resulting in a reduction in the volume of the fins. Therefore, according to the present invention, the oil cooler core 10 having the first oil/water port 1111 of the horizontal cross section of the first irregular shape can reduce the fluid flow resistance, thereby improving the heat dissipation efficiency. Further, as will be appreciated by those skilled in the art: the special-shaped structure has the effects of fool-proofing and mistake-proofing in installation, and technicians only need to align oil-water ports of special-shaped shapes of different tube plates when assembling the tube plates, so that the assembly of the two tube plates can be completed. Therefore, according to the utility model discloses an oil cooler core 10 of first oil water mouth 1111 that has the horizontal cross-section of first dysmorphism shape of an embodiment still has the installation simply, advantage that the installation effectiveness is high.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
