Benefits of technology

The present disclosure aims to solve four technical problems: pressure drop in the tube, stagnation of flow in the tube, reduction of power consumption of the fan, and alleviation of condensate water standing in the tube. These technical effects are achieved by providing a gas furnace that can address these problems individually.

Problems solved by technology

However, the above-mentioned US 2006 / 0213499 A1 may have the problem of a pressure drop in the tube and a flow stagnation at the center of the tube, since the baffle is inserted into the tube.
Another problem is that the power consumption of a fan increases with increasing resistance to gas flow in the tube with the baffle inserted in it.
Other problems include condensate water standing in the tube into which the baffle is inserted.

Abstract

Provided is a gas furnace. The gas furnace includes: a manifold with an exhaust port for discharging fuel gas; a nozzle attached to the exhaust port; a burner for burning a mixture of air and fuel gas ejected from the nozzle; a primary heat exchanger that provides a first flow path and allows a combustion gas produced by the combustion of the mixture to move through the first flow path; and a secondary heat exchanger located adjacent to the primary heat exchanger, that provides a second flow path and allows the combustion gas discharged from the primary heat exchanger to move through the second flow path, wherein the secondary heat exchanger includes: at least one tube forming the second flow path; and a baffle inserted into the at least one tube, the baffle including: a plate longitudinally extending in a lengthwise direction and twisted in the shape of a screw; and a plurality of holes formed to penetrate the plate.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority from Korean Patent Application No. 10-2019-0090923, filed on Jul. 26, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.FIELD OF THE DISCLOSURE[0002]The present disclosure relates to a gas furnace. More particularly, the present disclosure relates to a gas furnace with a baffle that can facilitate heat transfer and / or condensate water formation.RELATED ART[0003]Generally, a gas furnace is an apparatus that heats up a room by supplying air heated through heat exchange with a flame and high-temperature combustion gas produced by the combustion of a fuel gas.[0004]The gas furnace may have a primary heat exchanger and a secondary heat exchanger. The secondary heat exchanger is generally a finned tube heat exchanger.[0005]US 2006 / 0213499 A1 discloses a baffle that is inserted into a tube to enhance the heat transfer efficiency of the...
