Benefits of technology

The invention is a heat exchange system that helps improve the flow of water and the distribution of heat. This system is useful for machines that generate heat.

Problems solved by technology

In the heat exchange device described in the above publication, since each of the plurality of heat absorbing pipes extends in a zigzag manner in the forward and backward direction (horizontal direction), drainage performance is poor when water is discharged from the heat absorbing pipes.
As a result, a balance in distribution of water between the plurality of heat absorbing pipes deteriorates.

Embodiment Construction

[0016]The embodiments of the disclosure provide a heat exchange device capable of improving drainage performance and improving the balance of distribution of water and a heat source machine including the same.

[0017]A heat exchange device of an embodiment of the disclosure is a heat exchange device which is capable of recovering sensible heat and latent heat of a combustion gas. The heat exchange device includes a primary heat exchanger and a secondary heat exchanger. The primary heat exchanger is for recovering the sensible heat of the combustion gas. The secondary heat exchanger is disposed to overlap the primary heat exchanger in a vertical direction in a state in which the heat exchange device is installed and is for recovering the latent heat of the combustion gas. The secondary heat exchanger includes a plurality of first pipes, and a plurality of second pipes each alternately adjacent to each of the plurality of first pipes in a direction intersecting the vertical direction. E...

Abstract

The heat exchange device includes a primary heat exchanger and a secondary heat exchanger. The secondary heat exchanger is disposed to overlap the primary heat exchanger in a vertical direction in a state in which the heat exchange device is installed. The secondary heat exchanger includes a plurality of first pipes and a plurality of second pipes. Each of the plurality of first pipes and the plurality of second pipes extends in a zigzag manner in the vertical direction by a plurality of linear portions being connected to a plurality of curved portions in series. Each of the plurality of linear portions of each of the plurality of second pipes is disposed to be displaced from each of the plurality of linear portions of each of the plurality of first pipes in the vertical direction.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Japan application serial no. 2017-248716, filed on Dec. 26, 2017. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUNDTechnical Field[0002]The disclosure relates to a heat exchange device and a heat source machine, and more particularly to a heat exchange device having a primary heat exchanger and a secondary heat exchanger and a heat source machine having the same.Description of Related Art[0003]Conventionally, a heat exchange device including a primary heat exchanger for recovering sensible heat and a secondary heat exchanger for recovering latent heat has been proposed. This heat exchange device is described in, for example, Japanese Laid-open No. 2017-211173 (Patent Document 1). In the heat exchange device described in this publication, the secondary heat exchanger has a plurality of heat absorbi...
