Description
Technical Field
The utility model is applied to the technical field of heat exchangers, and particularly relates to a high-temperature protection structure of a heat exchanger.
Background
The existing hanging stove comprises a combustion chamber, a heat exchanger and a combustor, wherein the heat exchanger is arranged in the combustion chamber, the combustion chamber is arranged above the combustor, and the combustor is communicated with an external gas pipeline. When the burner works, the burner fully burns the coal gas and heats the heat exchanger in the combustion chamber, so that the heating water in the heat exchanger is heated to a proper temperature. In order to ensure that the heating water in the heat exchanger can reach the designated temperature, a temperature sensor is generally arranged on the outer wall of the water outlet pipe of the heat exchanger, when the water pump fails and stops working, the circulating flow of the heating water is stopped, the burner continuously heats the heat exchanger, the temperature of the heating water in the heat exchanger can be overhigh, when the temperature sensor senses the overhigh temperature, an induction signal is transmitted to an external control system, and the control system controls the hanging stove to stop working. However, because the temperature sensor is arranged on the outer wall of the water outlet pipe of the heat exchanger, the pipe wall temperature is always lower than the temperature of the heating water in the pipe according to the heat conduction principle, when the temperature sensor senses that the pipe wall temperature is too high, the temperature of the heating water in the pipe is too high, and the control system cannot respond timely.
The patent document with the publication number of CN205119505U proposes a wall-mounted boiler main heat exchanger icing protection device, which comprises a main heat exchanger 1, a controller, a low-temperature protection temperature controller 2 connected with the controller and a high-temperature protection temperature controller 4 connected with the controller, wherein the outer walls of a water inlet pipe joint and a water outlet pipe joint of the main heat exchanger 1 are respectively provided with an installation seat 3, and the low-temperature protection temperature controller 2 and the high-temperature protection temperature controller 4 are respectively installed on the installation seats 3. The high-temperature protection temperature controller 4 is used for detecting the temperature of the pipeline in the main heat exchanger 1, if the temperature is too high, the high-temperature protection temperature controller 4 is disconnected and transmits signals to the controller, and the controller controls the wall hanging stove to stop working so as to prevent the main heat exchanger from being damaged and scald users caused by the too high temperature. However, since the high temperature protection temperature controller 4 detects the temperature of the pipeline in the main heat exchanger 1, the temperature collected by the high temperature protection temperature controller 4 is not the actual water temperature according to the heat conduction principle, and when the pipeline temperature is detected to be too high, the water temperature is too high, so that the controller cannot timely control the wall-mounted furnace to stop working, and the safety is relatively low. If a heat exchanger high-temperature protection structure which is simple in structure, convenient to assemble and disassemble and capable of directly collecting water temperature can be designed, the problem can be well solved.
