Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

As shown in fig. 1 and 2, a water heating module includes: the heat exchanger comprises a shell 100, wherein the interior of the shell 100 is divided into a combustion chamber 110, a heat exchange chamber 120 and a condensation chamber 130 which are communicated in sequence from bottom to top; a burner 200, at least two burners 200 being installed in the combustion chamber 110, each burner 200 being supplied with gas by a separate gas inlet assembly 210; the heat exchanger 300 is installed in the heat exchange chamber 120, and the heat exchanger 300 comprises a plurality of layers of heat exchange tubes 310 connected in series; the condensing mechanism 400 comprises a plurality of fans 420 and a condensing pipe 410 installed in the condensing chamber 130, the fans 420 are installed at the top of the heat exchange chamber 120, the fans 420 pump the flue gas in the heat exchange chamber 120 into the condensing chamber 130, and a plurality of fins (not shown) are arranged on the outer wall of the condensing pipe 410.

As shown in fig. 2, three burners 200 are installed at the lower portion of the casing 100, and an air intake assembly 210 is independently connected to the bottom of each burner 200. Four layers of heat exchange tubes 310 are arranged in the heat exchange chamber 120, and each layer of heat exchange tubes 310 is surrounded on the horizontal plane of the layer to form a plurality of sections of tubes. When in use, the plurality of burners 200 work simultaneously, thereby effectively increasing the output of heat energy; each combustor 200 works independently, the opening and closing of different air inlet assemblies 210 can be controlled to control the starting and stopping of different combustors 200, and the combustors 200 can be conveniently overhauled or replaced. The high temperature flue gas generated by the burner 200 rises, water flows in the heat exchange pipe 310, and the water and the high temperature flue gas exchange heat through the heat exchange pipe 310. The flue gas after heat exchange continues to rise, and the flue gas in the heat exchange chamber 120 is pumped into the condensing chamber 130 by the fan 420. Water flows in the condensation pipe 410, and the heat exchange area of the water and the flue gas is increased through the fins, so that the waste heat in the flue gas is fully absorbed. Water preheats in condenser pipe 410, and the water after preheating flows back and heats in heat exchange tube 310, effectively improves heat exchange efficiency.

In some embodiments of the present invention, three burners 200 are installed side by side in the combustion chamber 110; existing heating modules typically use a single burner 200, with three burners 200 installed side-by-side for extremely high heat production.

As shown in fig. 3, in some embodiments of the present invention, a partition 420 extending upward is disposed in the condensation chamber 130, the partition 420 divides the condensation chamber 130 into a front chamber 430 and a rear chamber 440, the top of the front chamber 430 is communicated with the top of the rear chamber 440, the condensation pipe 410 is installed in the front chamber 430, the blower 420 is communicated with the lower portion of the front chamber 430, and a smoke exhaust port 441 is disposed on the rear side of the rear chamber 440. The fan 420 pumps the flue gas in the heat exchange chamber 120 to the front chamber 430 of the condensing chamber 130, where the flue gas exchanges heat with the water in the condensing tubes 410. The flue gas enters from the lower portion of the front chamber 430 and then flows upward. The flue gas flows across the top of the baffle 420 to the rear chamber 440 and is exhausted through an exhaust port 441 at the rear side of the rear chamber 440. The arrangement of the partition plate 420 ensures that the flue gas fills the front chamber 430, ensures that the flue gas is fully filled in the front chamber 430 to exchange heat with the condensing tube 410, and then flows to the rear chamber 440 to be discharged under the wind pressure of the fan 420.

Further, the fans 420 are connected to the top of the heat exchange chamber 120, and the number of the fans 420 is the same as the number of the burners 200. As shown in fig. 2, three burners 200 are arranged in the combustion chamber 110, and three fans 420 are arranged at the top of the heat exchange chamber 120, so as to ensure the flow speed of the flue gas in the heat exchange chamber 120.

In some embodiments of the present invention, the installation position of each blower 420 corresponds to the position of each burner 200. As shown in fig. 2, the three fans 420 are respectively located right above the three burners 200, the flue gas generated by each burner 200 can correspondingly rise under the action of each fan 420, and the formed airflow path can fully contact with the heat exchange pipe 310 for heat exchange. If only one fan 420 is provided, the flue gas flows toward the fan 420, and a single flow path is formed in the heat exchange chamber 120, so that part of the tubes of the heat exchange tube 310 cannot contact with the flue gas for heat exchange.

In some embodiments of the present invention, the heat exchanging pipe 310 is provided with fins (not shown), and the heat exchanging area is increased by the fins.

In some embodiments of the present invention, the heat exchange tube 310 is provided with a valve body, the valve body is located outside the heat exchange chamber 120, and the valve body can be used to control whether water flows through the heat exchange tube 310.
