TEMPERATURE CONTROL DEVICE FOR CRANKSHAFT BEARING SHELL

The present invention relates to the field of crankshaft bearing shells, and particularly to an temperature control device for a crankshaft bearing shell, comprising a first crankshaft body; in which a second crankshaft body is mounted at a top end of the first crankshaft body; a second bearing shell body is mounted inside the first crankshaft body; a first bearing shell body is mounted inside the second crankshaft body, a bottom end of the first bearing shell body being connected to the second bearing shell body; and the temperature of the first bearing shell body and the second bearing shell body can be detected by a temperature detector. A hydraulic pump operates to draw the coolant liquid inside a cooling tank into a first water pipe. The coolant liquid enters a cooling bath through the first water pipe. The coolant liquid entering the cooling bath can take away the heat of the first crankshaft body itself, so as to cool down the first crankshaft body and the second bearing shell body rapidly, ensure the operational environment for the first bearing shell body and the second bearing shell body, reduce loss of the second bearing shell body and the first bearing shell body due to high temperature, and improve operation efficiency of the first bearing shell body and the second bearing shell body.
