Description

Technical Field

[0001] The utility model relates to the technical field of oil temperature machines, in particular to a plate heat exchanger component and an integrated 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 circulating 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. A plate heat exchanger is installed inside the oil temperature controller. The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates.

[0003] Existing plate heat exchangers are generally fixed directly to the sheet metal structure inside the oil temperature machine by bolts during production. However, since there are many parts and a small space inside the oil temperature machine after production, the subsequent maintenance of the plate heat exchanger assembly and the integrated oil temperature machine will be affected.
