Problems solved by technology
[0004] In the existing heat exchanger, the position of the heat exchange tube in the box is fixed. However, in actual work, when burning at a low level and low power, the temperature of the flue gas and the height of the flame are low, and the heat exchange is not insufficient. When burning at high speed and low power, the flue gas temperature and flame height are relatively high, and the heat exchange fins and heat exchange tubes are easy to burn through, shortening the service life

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] Such as Figure 1 to Figure 5 As shown, the heat exchanger 10 in this embodiment includes a heat exchange box 2, a heat exchange tube 1, a lifting mechanism 3 and a vibration mechanism 4. The heat exchange tube 1 has a heat exchange section 11 located in the heat exchange box 2, A plurality of heat exchange fins 13 are arranged on the heat exchange section 11 .
[0027] Both sides of the heat exchange box 2 are provided with guide holes 21 for the heat exchange section 11 to move up and down. The heat exchange box 2 is provided with a lifting mechanism 3 and a transmission bracket 5a drivingly connected to the lifting mechanism 3. The transmission bracket 5a is in the Under the action of the lifting mechanism 3 , the heat exchange section 11 can be driven to move up and down relative to the inside of the heat exchange box 2 .

The invention discloses a heat exchanger. The heat exchanger comprises a heat exchange box body and a heat exchange tube, the heat exchange tube is provided with heat exchange sections located in theheat exchange box body, the heat exchanger is characterized in that two sides of the heat exchange box body are provided with guide holes allowing the heat exchange sections to move up and down, the heat exchange box body is provided with a lifting mechanism and a transmission support connected with the lifting mechanism in a driving mode, the transmission support can drive the heat exchange sections to move up and down relative to the heat exchange box body under the action of the lifting mechanism. The application also discloses a gas water heater. The heat exchange sections can be lifted according to the combustion load and a set temperature, so that the temperature difference between the inside and outside of the heat exchange tube is improved, and the heat exchange efficiency and thesafety heat exchange are improved.
Description
technical field [0001] The invention relates to a component of a gas water heater, in particular to a heat exchanger applied to a gas water heater or a dual-purpose furnace, and also relates to a gas water heater. Background technique [0002] Gas water heaters have the characteristics of fast hot water output, good constant temperature performance, high efficiency and energy saving, and are loved by more and more families in modern life. Gas water heater mainly includes three major systems: water system, gas system and electric control system. The waterway system includes heat exchangers and water inlet and outlet joints. [0003] The heat exchanger is set above the burner, and generally includes a box body, water inlet pipe, water outlet pipe, heat exchange tube and heat exchange fins. A plurality of heat fins are stacked successively and passed on the straight section of the heat exchange tube. Related documents can refer to the Chinese utility model patent "heat excha...
