In the two-stage cooling graphite heat exchange, the upper and lower stages of cooling are separated through the tetrafluoro transition ring, so that the graphite blocks are prevented from being broken due to uneven heating caused by large heat exchange temperature difference in the upper and lower shells, and the normal use of the heat exchanger is ensured.
As a further improvement of the novel plastic bottle, the lower cover plate, the upper cover plate, the flange and the upper O-shaped ring are connected through bolts and springs.
As a still further improvement of the present application, the shell side is divided into two independent systems by a lower O-ring and a tetrafluoro transition ring between the lower and upper shells.
As a further improvement of the present application, chilled water is fitted in the lower shell side, and circulating water is fitted in the upper shell side.
