Description

Technical Field

[0001] The utility model relates to the technical field of oil temperature machines, in particular to a heat conduction oil return component and an oil temperature machine. Background Art

[0002] As the name implies, the oil temperature controller is a mold temperature controller that uses heat transfer oil as a heat transfer medium. The oil temperature controller itself is equipped with an oil storage tank. When working, the heat transfer oil enters the system from the oil storage tank and is pumped into the mold or other equipment that needs temperature control through a circulation pump. After the heat transfer oil comes out of the temperature-controlled equipment, it returns to the system, and the cycle repeats. The heat transfer oil is heated by the heater. When the medium temperature detected by the temperature sensor reaches the set value, the heater stops working. When the temperature is lower than the set value, the heater starts working. When the temperature reaches the set value, it stops working again, and the cycle repeats. In actual use, the oil temperature controller needs to be connected to the equipment that needs temperature control through a connecting pipe so that the heat transfer oil can circulate to control the temperature of the equipment.

[0003] The connecting pipe of the existing oil temperature machine is usually connected to the oil temperature machine body by a threaded connection. Different pipe diameters are required when connecting different equipment, so the connecting pipe needs to be replaced. The threaded connection of the connecting pipe happens to be at the stress point. Frequent rotation and replacement of the connecting pipe thread will cause wear and tear on the connecting pipe connection, causing the connection to loosen, resulting in leakage at the connection.
