The present invention relates to a heat transfer module (HT M: Heat Transfer Module) for a gas boiler, and more particularly, to a dual type heat transfer module for both heating and hot water that allows heating and hot water to be simultaneously used as one module. will be.

A typical heat boiler heat transfer module (HT M) is installed in the inner central portion of the heat transfer module main body 1 as shown in FIG. 1 (a) and (b) to burn a mixture of fuel and air to produce a high temperature. Cylindrical metal burner (2) for dissipating heat, a plurality of heating-side heat transfer pipes (4) and the main body installed in combination with a plurality of spheres (3) at regular intervals around the metal burner (2) The heat exchanger header (5) coupled to the upper side of the (1) and the exhaust duct (6) in which the exhaust gas is discharged is roughly composed, the heating-side heat pipes (4) are interconnected and one side heat pipe ( A heating water inlet pipe 7 is connected to one end of 4a) and a heating water discharge pipe 8 is connected to the other heat transfer pipe 4b.

In general, the heat transfer module for a gas boiler configured as described above has a mixture of fuel and air combusted in the metal burner 2 and is disposed radially adjacent to the periphery of the burner 2 with the hot combustion gas generated at this time. The heating effect is obtained by heating the fluid passing through the plurality of heating-side heat pipes 4, and thus, the light generated during combustion by the plurality of spheres 3 coupled between the heating-side heat pipes 4. The heat transfer is performed by using a radiation effect. However, as described above, the conventional heat transfer module is composed of only a primary heat exchanger that heats only heating water (or any fluid), and therefore, when heating other fluids such as hot water, a separate secondary heat exchanger is required. The disadvantage was that the overall size was increased and it was not suitable for a compact sized gas boiler module for both heating and hot water.

The object of the present invention devised in view of this is to solve the conventional combination as described above, while heating and hot water can be used simultaneously in one module, while the compactness of the gas boiler that realizes the compactness of the product, dual type for both heating and hot water The present invention provides a heat transfer module.

The purpose of the present invention as described above is to use a conventional heat transfer module as it is, the heating tube is inserted into the heating tube with a large heat transfer effect is formed by forming a hot water side heat transfer tube and installing a diaphragm in the heat exchanger header heating side heat transfer It is achieved by providing a dual type heat transfer module for both heating and hot water of a gas boiler, which is formed by separating the tubular header and the header for the hot water side heat transfer pipe.

Hereinafter will be described in more detail on the basis of the accompanying drawings of the present invention.

Figure 2 (a) and (b) is a longitudinal cross-sectional view and a cross-sectional view showing the configuration and operation of the dual type heat transfer module for heating and hot water in accordance with the present invention, dual type for both heating and hot water according to the present invention as shown therein The heat transfer module has a cylindrical metal burner (2) installed in the inner center of the heat transfer module main body (1), and a plurality of heating-side heat transfer tubes (4) in which a plurality of spheres (3) are coupled adjacent thereto are installed radially. In the heat transfer module for a gas boiler in which a heat exchanger header (5) is coupled to the upper side of the main body (1), a hot water side heat pipe (10) is provided in the heating side heat pipe (4), and In the heat exchanger header 5, a diaphragm 11 is provided to separate the heat exchanger header 5a and the hot water heat exchanger header 5b, and the end of one side hot water heat exchanger tube 10a is formed. There is a hot water inlet pipe (12) The other specific hot water side heat transfer pipe 10b is connected to the hot water outlet pipe 13 is configured to be connected.

The hot water-side heat transfer tube 10 is preferably to use a spiral tube having a large heat transfer effect.

In the drawings, the same reference numerals are given to the same parts as in the conventional configurations.

Looking at the operation and effects of the heating, hot water combined heat transfer module according to the present invention configured as described above are as follows.

The heat transfer module for both heating and hot water according to the present invention allows the low temperature heating water to be heated while passing through the heating-side heat transfer pipe 4 which performs the first heat exchange with the high temperature product (exhaust gas) of the unburned mixture burned in the cylindrical burner (2). The effect of obtaining a heating effect is similar to the same as in the prior art, but in the present invention, it is possible to use hot water at the same time as in the prior art.

That is, when hot water is used, the upper and lower portions 5a of the heat exchanger header 5 separated by the diaphragm 11 by performing heat exchange with the low temperature water introduced through the hot water inlet pipe 12 through the heating water heated by the hot gas. Hot water and heating water pass through 5b, respectively, and hot water of high temperature flows out through the hot water outlet pipe 13 by the heat exchange action.

As such, the present invention can combine the use of heating and hot water without a separate secondary heat exchanger using one heat transfer module.

As described in detail above, the heat transfer module according to the present invention forms a hot water pipe by installing a spiral tube in a plurality of heating pipes installed radially with respect to a cylindrical metal burner, and installing a diaphragm in the heat exchanger header to install a heat pipe on the heating side. Separated from the header for the pipe and the header for the hot water pipe, it is possible to use both heating and hot water simultaneously in one module, but also to realize the compactness of the product and to separate the second heat exchanger for the use of hot water. Since no equipment is needed, cost increase factors such as investment in mold due to the manufacture of heat exchanger for hot water can be eliminated. It is possible to reduce manufacturing costs.

In other words, it is possible to manufacture a compact and inexpensive product while adding the function of using hot water.
