Description

Technical Field

[0001] The present application relates to the field of heat exchange technology, and in particular to a high-temperature heat exchange device. Background Art

[0002] A heat exchanger is a high-temperature or low-temperature liquid medium that heats or cools the target liquid, thereby achieving heating and cooling of the target liquid.

[0003] In the existing high-temperature heat exchange device, water flows in the pipe and exhaust gas flows in the pipe during the heat exchange process. Since the pipe volume is relatively small, the volume of liquid that can be accommodated is also small, resulting in a large temperature rise of the liquid in the pipe when the temperature adjustment range is small. The discharged liquid is prone to temperature instability, so it needs to be improved.

[0004] Based on this, the utility model provides a high-temperature heat exchange device to solve the above problems. Utility Model Content

Several electric heaters 400 are arranged on the outside, and the several electric heaters 400 are mounted on the heat exchange tube 200 to perform heat exchange on the water flowing outside the heat exchange tube 200. A temperature sensor 300 is arranged on the side wall of the high-temperature water outlet 130. A solenoid valve 132 is fixedly connected to the high-temperature water outlet pipe 131, and the solenoid valve 132 is electrically connected to the temperature sensor 300. An operational amplifier 140 is arranged on the surface of the shell 100, and the operational amplifier 140 is electrically connected to the temperature sensor 300 and the solenoid valve 132; the operational amplifier 140 is provided with a temperature threshold signal. When the temperature signal monitored by the temperature sensor 300 is greater than the temperature threshold signal, the operational amplifier 140 sends an opening signal to the solenoid valve 132, so that the solenoid valve 132 is opened, and the high-temperature hot water after the low-temperature heat exchange is discharged, thereby realizing heat exchange.

[0036] Reference Figure 2 A fixing device 210 is provided at the bottom of the heat exchange tube 200, and the fixing device 210 is fixedly connected to the insulation layer 110. The fixing device 210 is used to fix the heat exchange tube 200. The fixing device 210 includes a fixing seat 211 and a fixing buckle.

[0037] The implementation principle of a high-temperature heat exchange device in an embodiment of the present application is as follows: when an external low-temperature water source is needed, the low-temperature water source enters the low-temperature water inlet 120 through the low-temperature water inlet pipe 121 and then flows into the inner cavity of the shell 100. The electric heater 400 of the heat exchange tube in the inner cavity of the shell 100 heats the heat exchange tube, so that the low-temperature water source flowing outside the heat exchange tube undergoes heat exchange. When the low-temperature water source is heat exchanged to become a high-temperature water source, when the temperature sensor 300 detects that the temperature signal of the high-temperature water source reaches a preset temperature threshold signal, the operational amplifier 140 sends an opening signal to the solenoid valve 132, so that the solenoid valve 132 opens, so that water with a stable temperature is discharged from the high-temperature water outlet 130 to the high-temperature water outlet pipe 131, thereby achieving a stable temperature discharge of the high-temperature liquid.
