Heat exchanger and oil well paraffin removal device with same

The invention discloses a heat exchanger and an oil well paraffin removal device with the same. The heat exchanger comprises an inner pipe with an oil inlet and an oil outlet, a plurality of outer pipes, a plurality of branch pipes and superconductive liquid, and is characterized by comprising a superconductive liquid accommodating part, wherein the superconductive liquid accommodating part is provided with a storage inner cavity, and is arranged above the heat exchanger; and the storage inner cavity of the superconductive liquid accommodating part is communicated with the uppermost outer pipethrough a conduit. When a burner works, the superconductive liquid is subjected to thermal expansion and then enters the superconductive liquid accommodating part; and after the burner is turned off,the superconductive liquid is ensured to exist in all cavities among the inner pipe and the outer pipes after the volume of the superconductive liquid is reduced. Therefore, heat on the periphery ofthe upper part of the heat
