Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments, but it should not be construed that the scope of the present invention is limited to the embodiments described below.

Referring to fig. 1-3, the structure of a spiral heat exchanger channel of the present invention is shown. The spiral heat exchanger water channel is suitable for a gas wall-mounted furnace, wherein the heat exchanger comprises a shell 1, a water channel 2 and a heat exchanger 3, wherein the water channel 2 is integrally arranged in the shell 1, namely the water channel 2 is assembled in the shell 1, the heat exchanger 3 is sleeved in the water channel 2, the water channel 2 is attached to the heat exchanger 3, the integral water channel is spirally distributed, the heat exchange area is increased, the heat in the heat exchanger is fully exchanged, and therefore the heat efficiency is improved, and further described below.

As shown in figure 1, the shell 1 is formed by assembling two shells in a split way, and the two sides of the shell are respectively welded with the fabrication holes 6, so that the installation condition of the inner water channel 2 can be conveniently observed, and the shell can be closed after meeting the requirements. The water channel 2 is a single channel, and is in a turn-back type or spiral shape, and the layout is simple. The water channel 2 is provided with a water inlet 4 and a water outlet 5, the water inlet 4 and the water outlet 5 are positioned on the same side of the water channel so as to be convenient for connecting an outer pipe, and the water inlet 4 and the water outlet 5 can be respectively provided with a water pressure sensor so as to judge whether the water channel is blocked or not by monitoring the pressure difference between the two positions. The heat exchanger 3 can be assembled by two heat exchanger components, and heat exchange cores (preferably column-type small hollow cores, commonly called nail cores) are transversely densely distributed on the wall body of the heat exchanger components to form a corresponding heat exchange core array, wherein the lengths of the heat exchange cores at the lower parts of the heat exchanger components are respectively increased, the lengths of the heat exchange cores at the upper parts of the heat exchanger components are respectively consistent, so that a combustion chamber 7 is formed in the space between the heat exchange cores at the lower parts to receive heat, and the heat exchange cores at the upper parts can better transfer heat. For convenient to use and assurance safety, combustion chamber 7 position sets up ignition hole and temperature measurement hole, and combustion chamber 7 offside sets up the smoke collecting area, and no longer the repeated description.

The utility model discloses optimize the overall arrangement form to the water course, specifically as follows.

As shown in fig. 2-3, the water channel 2 of the present invention has an integrated tubular water channel body with an open slot, i.e. the water channel 2 is generally tubular, and a vertical slot 23 is formed on one side of the tube.
