A high temperature water heater

Abstract

The invention discloses a high-temperature water heater. The high-temperature water heater comprises an aluminum fin type heat exchanger; a water outlet pipe is arranged at a water outlet end of the aluminum fin type heat exchanger, and is communicated with the internal of the aluminum fin type heat exchanger; a fire grate burner is arranged below the aluminum fin type heat exchanger, and is provided with an intake pipe; the intake pipe is communicated with the fire grate burner; an enhanced heat exchanger is arranged between the aluminum fin type heat exchanger and the fire grate burner; a water inlet pipe is arranged at a water inlet end of the enhanced heat exchanger; a water outlet end of the enhanced heat exchanger is connected with a water inlet end of the aluminum fin type heat exchanger; the enhanced heat exchanger includes a horizontally arranged main pipe; the main pipe is bent in a zigzag manner; multiple fin pipes with opened two ends are arranged in the main pipe; the fin pipes longitudinally penetrate through the main pipe; and one end of the main pipe is connected with the water inlet pipe, and the other end is connected with the water inlet end of the aluminum fin type heat exchanger. The high-temperature water heater is high in utilization rate of heat energy, high in heat exchange efficiency and low in manufacturing cost.

Description

technical field [0001] The invention relates to a high-temperature hot water machine. Background technique [0002] refer to figure 1 , the working principle of the traditional hot water machine is as follows: the natural gas is directly injected into the fire row burner 3 and burns, and the heat heats the aluminum finned heat exchanger 1 through heat transfer, so that the aluminum finned heat exchanger 1 The water inside is heated and taken away to realize the function of producing hot water. [0003] Traditional water heaters are divided into single-layer aluminum-fin heat exchanger water heaters and double-layer aluminum-fin heat exchanger water heaters. Single-layer aluminum fin heat exchanger water heaters exist as follows Defects: low heat exchange efficiency and large heat loss; the double-layer aluminum fin heat exchanger type water heater has the following defects: high manufacturing cost; the heat exchange rate of the upper aluminum fin heat exchanger is not high...

Problems solved by technology

[0003] Traditional water heaters are divided into single-layer aluminum-fin heat exchanger water heaters and double-layer aluminum-fin heat exchanger water heaters. Single-layer aluminum fin heat exchanger water heaters exist as follows Defects: low heat exchange efficiency and large heat loss; the double-layer aluminum fin heat exchanger type water heater has the following defects: high manufacturing cost; the heat exchange rate of the upper aluminum fin heat exchanger is not high, and the flue gas fluidity weakened, incomplete combustion

[0004] In addition, the oxygen supply method of the fire row burner of the traditional hot water machine is passive, that is, when the natural gas enters the fire row burner, the air flow brings air into the fire row burner, the mixing amount of air is limited, and the natural gas cannot fully Combustion, the combustion efficiency is low; when the natural gas is not fully burned, the intake of natural gas can only be reduced unilaterally, so that the heat production capacity of the fire exhaust burner cannot be maximized
