Detailed Description

Example (b): referring to fig. 1 and fig. 2, the embodiment of the present invention provides a novel temperature controller, which includes a frame 1, a water tank 2, a water pump 3, a heater 4, a tube cooler 5, and a valve 6. In this embodiment, the valve 6 is preferably a pneumatic angle seat valve, and is easy to install and convenient to operate. In other embodiments, the valve 6 may be a solenoid valve.

Frame 1 is last to be equipped with first crossbearer 7 and second crossbearer 8 in proper order from last to lower, water tank 2 sets up on first crossbearer 7, shell and tube cooler 5 sets up at second crossbearer 8.

Specifically, the tubular cooler 5 comprises a cylinder, a refrigerant coil and two end covers, wherein the two end covers are sealed at two ends of the cylinder, an opening is formed in the side wall of one end of the cylinder to form a heat-conducting medium outlet end, and an opening is formed in the side wall of the other end of the cylinder to form a heat-conducting medium inlet end; wherein, one end cover is provided with two openings, the refrigerant coil is positioned in the cylinder body, and the head and the tail of the refrigerant coil are correspondingly connected with the two openings to correspondingly form a cooling water outlet end and a cooling water inlet end.

The water pump 3 is arranged at the bottom of the rack 1, the heater 4 is arranged above the water pump 3, one end of the heater 4 is connected with the output end of the water pump 3, the other end of the heater 4 is connected with the heat-conducting medium inlet end, the input end of the water pump 3 is connected with the water tank 2, and the valve 6 is arranged at the cooling water inlet end.

The heat-conducting medium outlet end of the tubular cooler 5, the roller cooling pipeline of the extruder 10, the water pump 3, the enameling machine and the heat-conducting medium inlet end of the tubular cooler 5 are sequentially connected through pipelines to form a cooling loop. The water tank 2 is connected to the cooling circuit for the purpose of replenishing water.

And a cooling water outlet end of the tubular cooler 5 is connected with a water inlet end of the water cooler 9, and a cooling water inlet end of the tubular cooler is connected with a water outlet end of the water cooler 9 to form a cooling loop, so that the cooling effect is further improved.
