Zusammenfassung:	The utility model belongs to the technical field of tubular heat exchangers, and discloses an anti-freezing tubular heat exchanger. The anti-freezing tubular heat exchanger comprises a heat exchanger outer box, flanges are fixedly connected to the left side and the right side of the heat exchanger outer box, a front cover is movably connected to the left sides of the flanges, a hot water inlet is formed in the left side of the front cover, a cold water inlet is formed in the top of the heat exchanger outer box, and a cold water outlet is formed in the bottom of the heat exchanger outer box. A rear cover is movably connected to the right side of the heat exchanger outer box through a flange, a hot water outlet is formed in the bottom of the rear cover, and supporting columns are fixedly connected to the bottom of the heat exchanger outer box. According to the anti-freezing tubular heat exchanger, water left in the heat exchanger can be blown out of the heat dissipation pipe in time through the fan when the hea
