| 摘要 |
The present invention relates to a structure of a housing of a temperature control unit in a temperature control apparatus for injection mold, the housing including: a main housing (200) having a cavity therein, an inlet (210) at one end thereof through which temperature control fluid flows in, and an outlet (220) at the other end thereof through which fluid for temperature control is discharged; and an outer housing (300) having an open front connected to the outer surface of the main housing (200), one end enclosing the inlet (210), and the other end provided with a connecting pipe (310) connected to a pump for circulating the temperature control fluid. The present invention is characterized in that the temperature control fluid flowing in the outer housing (300) through the connecting pipe (310) touches the outer surface of the main housing (200), so a first heat exchange is induced before the temperature control fluid flows into the inlet (210) of the main housing (200). |
