What parts are the common coolers of injection molding machines made up of?How does it work?
More commonly used cooler structures are snake-shaped pipe type and column pipe type.The following figure shows the common column tube cooler structure.
Can see from the table, the column tube cooler by multiple row of cooling water pipe assembly together, installed inside a circular coat, coat ends for sealing end cover, arrangement of the pipe ends by interconnected, cooling water inlet and the other end by the end.A certain quantity of heat of the hydraulic oil flow from the top coat in the cooler, the cooling water flow between the tube wall, hot oil and cooling water through the exchange of cold and heat conduction metal wall, make the oil temperature is reduced, and then the top from the other end.In order to increase the contact area of the hot oil and cooling water pipe and stay within the mantle cavity of the time, set the body a few period of clapboard, the cooling pipes into several segments, lengthen the hot oil flows through the route, and extended the conduction time of cold and hot medium, achieve good hot oil cooling and cooling effect.
