[0006] Upper end cover; the upper end cover is mounted on the upper part of the heat exchanger, and a first upper through hole and a second through hole are provided on the upper end cover, the cold water inlet pipe passes through the first through hole and is exposed, and the cold water outlet pipe passes through the second through hole and is exposed; and

[0007] Lower end cover; the lower end cover is installed at the lower part of the heat exchanger, and a warm water outlet pipe and a hot water inlet pipe are provided on the lower end cover. The hot water inlet pipe is connected to the water inlet of the second heat exchange array, and the warm water outlet pipe is connected to the water outlet of the second heat exchange array.

[0008] In this embodiment, a first upper mounting hole group is provided on the upper portion of the heat exchanger, and a second upper mounting hole group is provided on the upper end cover. The second upper mounting hole group cooperates with the first upper mounting hole group to fix the upper end cover on the upper portion of the heat exchanger.

[0009] In this embodiment, a first lower mounting hole group is provided at the lower portion of the heat exchanger, and a second lower mounting hole group is provided on the lower end cover. The second lower mounting hole group cooperates with the first lower mounting hole group to fix the lower end cover on the lower portion of the heat exchanger.

[0010] In this embodiment, two upper mounting brackets are provided on the upper end cover, and one lower mounting bracket is provided on the lower end cover.

[0011] Compared with the prior art, the utility model has the following advantages: the upper end cover and the lower end cover are designed differently, which effectively prevents the upper end cover and the lower end cover from being installed reversely, and has high installation efficiency and is convenient to install.
