A heat exchanger using medium oil is provided to obtain heat energy with high efficiency. A heat exchanger comprises an electric heater (7), heat exchanger body (6), packing (8), packing groove (10), heat radiation pin (4), ventilation pipe (3), and supplementary oil hole (2). The electric heater heats media oil. The packing and packing groove prevent leakage of oil when coupling the main body with the electric heater. |
