Embodiment 1

[0112]Example 1: The heat exchanger 1 for the gas condenser boiler, the heat exchanger provided with a suitable container body 2, at least one tube bundle 3, at least one temperature sensor device 4, wherein the tube bundle 3 is surrounded by the pipe 3. The central axis spiral wrap is made, suitable for forming a suitable turn to define the combustion chamber 300, and is provided with the first end 31 and the second end 32, the first end for the heat transfer fluid to be heated, said The second end is used as an outlet of the heat transfer fluid.

[0113] in:

[0114] - The exchanger 1 is provided with a separator 5, the separator adapted to divide the combustion chamber 300 into a first sensitivity chamber 310 and a second condensing chamber 320;

[0115] It is characterized in that

[0116] - The spacer 5 includes a disc-shaped element having a cross profile 51 with a spiral pattern, which is provided with an insulating material layer 50;

[0117] - The spacer 5 can be screwed ...

Embodiment 2

[0118] Example 2: The heat exchanger according to Embodiment 1, characterized in that the first end 31 and the second end 32 are protrude from the container body 2 to be proxably proximally from the outside.

Embodiment 3

[0119] Example 3: The heat exchanger according to Embodiment 1 or Embodiment 2, characterized in that the sensor device 4 is in direct contact with the surface of the tube bundle 3.

Abstract

The invention relates to a heat exchanger (1) for gas condensing boilers, which is provided with a container body (2) within which at least one pipe bundle (3) is disposed to delimit a combustion chamber (300). The at least one pipe bundle (3) is made by a pipe spiral wound around a central axis. A first end (31) of the pipe serves as an inlet for the heat transfer fluid to be heated. A second end (32) of the pipe serves as an outlet for the heat transfer fluid. The pipe bundle (3) is made as a single component defined by a seamless single element. The pipe bundle has an elliptical section with a first end (31) and a second end (32) each having a circular section projecting from the container body, so as to be accessible from the outside, to ease the operations of connection of the first and the second ends to the pipes of the water system. The application also relates to a method of manufacturing the pipe bundle and a method for manufacturing the heat exchanger for gas condensing boilers.

Description

[0001] This sub-case application is based on Chinese Patent Application No. 201780044658.4 (its International Application No. PCT / IB2017 / 000828), filed on July 11, 2017, entitled "boiler for heat exchanger" of the divisional application. Technical field [0002] The present invention relates to a heat exchanger for a boiler or the like. Background technique [0003] Accordingly, the present invention is in high yield (the yield) heat generator field (output (refer to the calorific value) in the range of 95 to 100%), in particular for room heating and / or domestic hot water production condensing boilers. Typically, the boiler is a device in which water to be heated (for room heating and sanitary purposes) through a gas burner fitted with a heat exchanger. [0004] The gas burner may comprise a bundle, the bundle is preferably spiral wound, bundle by the turns (turns) the combustion gases or fumes generated by a gas burner through which to transfer heat to pass through it water...
