HEAT EXCHANGER

摘要

The present invention relates to a heat exchanger. The heat exchanger includes a shell; an inlet pipe which guides heat source water into the shell; a coolant tube which has a spiral pipe unit arranged in the shell and lets a coolant to pass through; and an outlet pipe which discharges the heat source water after the heat source water and the coolant tube engage in a heat exchange process. A spiral pipe unit forms a gap between turns. A heat source guide protruding to the gap is installed in the shell not to install an additional baffle to guide the flow of the heat source water. The present invention uses a simple structure to discharge the heat source water after conducting a heat exchange process between the heat source water and the spiral pipe unit with the maximum efficiency.
