1. A power-generating apparatus comprising:
a housing configured for a fluid to flow through it, the housing including a flat surface of which at least a portion of a wall surface is made of metal;
thermoelectric modules disposed on the flat surface of the housing; and
thermal insulating members disposed on side surfaces of the thermoelectric modules on the flat surface of the housing,
wherein the fluid is configured to flow into the housing through an inlet pipe, and the fluid is configured to be discharged to the outside of the housing through an outlet pipe,
wherein the housing includes a plurality of branch pipes through which the fluid having flowed along the inlet pipe branches and passes, and the plurality of branch pipes are combined in the outlet pipe,
wherein an angle formed by a first inner surface of a first region constituting a first branch pipe of the plurality of branch pipes and a second inner surface of a second region constituting a second branch pipe of the plurality of branch pipes on one side of the first region is 80° to 100°,
wherein an angle formed by the first inner surface and a third inner surface of a third region constituting a third branch pipe of the plurality of branch pipes on an other side of the first region is 80° to 100°,
wherein the thermoelectric modules include a first thermoelectric module disposed on a first outer surface of the first region, a second thermoelectric module disposed on a second outer surface of the second region and a third thermoelectric module disposed on a third outer surface of the third region,
wherein the second inner surface and the third inner surface face toward each other, and
wherein the first outer surface is an opposite surface of the first inner surface, the second outer surface is an opposite surface of the second inner surface, and the third outer surface is an opposite surface of the third inner surface.
