As shown in FIGS. 4 to 7, the fryer unit and the heat exchange system according to the embodiment of the present invention reduce the external heat of the fryer by reducing the waste heat conducted to the front part of the oil vat to reduce the external temperature of the fryer, The safety of use of the fryer can be improved.

Since most of the heat of combustion can be sent to the heat exchange tube, it is possible to provide a heat exchange system that concentrates on the heat by reducing the loss of heat of combustion.

By reducing waste heat, it is possible to reduce the maintenance cost through energy saving and to simplify the welding production of complicated heat exchange tubes, which can reduce the manufacturing cost, production cost and input materials and resources.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken as limiting of the scope of the inventions. do.
