The invention discloses a heat exchanger lifting mechanism and a crystal growing furnace system. The heat exchanger lifting mechanism comprises a heat exchanger, a fixed piece and a lifting mechanism,wherein one end of the heat exchanger is configured to penetrate through a furnace body of a crystal growing furnace, be connected with a crucible in the crystal growing furnace and be in heat exchange with the crucible; the heat exchanger is configured to be in sliding fit with the wall surface of the furnace body; the fixed piece is configured to be in opposite position with the crystal growingfurnace; the lifting mechanism is connected with the fixed piece and is in opposite position with the fixed piece; the lifting mechanism is in transmission connection with the heat exchanger; the lifting mechanism is configured to drive the heat exchange and slide relative to the furnace body so as to change a position relationship of the lifting mechanism relative to the furnace body. Accordingto the technical scheme provided by the invention, the problem that crystal quality is affected due to relative variation of the position of the heat exchanger in existing crystal growing equipment can be solved.
