Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange devices, and particularly relates to a combustion type heat exchange device. Background Art

[0002] Currently, heating devices on the market (coal-fired heating stoves, gas heating stoves, gas wall-mounted boilers, etc.); the structures of heating stoves are all composed of a combustion chamber, a heat exchanger, a flue, and a blower.

[0003] Their structures all adopt sandwich barrel type, vertical tube type, horizontal tube type, etc. The combustion chamber is in the center of the sandwich barrel, and the heat exchange medium is between the inner and outer walls of the sandwich barrel, in the vertical tubes and horizontal tubes. The heat released by combustion is exchanged through the inner wall of the sandwich barrel and the vertical and horizontal tubes. The heat exchange area and time in the combustion chamber and the heat exchange area are very limited, and the heat cannot be fully exchanged and is then discharged into the atmosphere through the flue. The temperature of the flue reaches above 100 degrees Celsius.

[0004] The currently used household combustion type heating devices have the following problems: The existing combustion type heating devices (including floor-standing and wall-mounted types) are all composed of a combustion chamber, a heat exchanger, a flue, a blower, etc.; but the structures of the heat exchangers are all barrel type, vertical tube type or horizontal tube type, etc. Under the same combustion rate, the heat flow rate released by combustion is not proportional to the heat exchange rate in the heat exchanger (that is, the greater the combustion amount, the lower the thermal efficiency). Approximately 30%-45% of the heat released by combustion will be discharged into the atmosphere through the flue due to the low heat exchange rate; resulting in very low thermal efficiency of the heating device and an increase in the economic cost of heating by about 30%. Therefore, a combustion type heat exchange device is proposed. Summary of the Invention

[0021] In this embodiment, specifically, the heat exchange mechanism 13 includes a circular box body 130, a fan 131, a combustion chamber 132, a spiral heat exchange tube 133, an exhaust pipe 134, an exhaust solenoid valve 135, a liquid injection pipe 136, a liquid injection solenoid valve 137, a liquid discharge pipe 138 and a liquid discharge solenoid valve 139. Among them, the circular box body 130 is arranged on the upper surface of the fixing plate 15, and the fixing frame 12 is arranged on the outer wall of the circular box body 130. The combustion chamber 132 is arranged on the lower surface of the circular box body 130 and passes through the operation through hole 5. The spiral heat exchange tube 133 is arranged inside the circular box body 130, and the bottom end of the spiral heat exchange tube 133 sequentially penetrates through the circular box body 130 and the combustion chamber 132. The spiral heat exchange tube 133 is fixedly connected to the circular box body 130 and the combustion chamber 132.

[0026] When the present invention is in operation: The relevant personnel control the liquid injection solenoid valve 137 and the exhaust solenoid valve 135 to open through the control panel 4. The liquid injection pipe 136 injects the heat exchange medium into the circular box body 130. The heat exchange medium in the circular box body 130 discharges the air through the exhaust pipe 134. After that, when the relevant personnel control the liquid injection solenoid valve 137 and the exhaust solenoid valve 135 to close through the control panel 4, the fan 131 is turned on. Then, the relevant personnel burn fuel in the combustion chamber 132 for heating. The fan 131 is used to transmit the gas burned in the combustion chamber 132 into the spiral heat exchange pipe 133. The heat generated by the gas in the spiral heat exchange pipe 133 is transmitted into the circular box body 130 to heat the heat exchange medium in the circular box body 130. After that, the gas after heat exchange is discharged through the smoke exhaust bellows 2. When the heat exchange medium is heated up, the relevant personnel control the exhaust solenoid valve 135 and the liquid discharge solenoid valve 139 through the control panel 4 to facilitate the discharge of the heated heat exchange medium in the circular box body 130 through the liquid discharge pipe 138, improving the heat exchange efficiency and increasing the heat exchange area.
