Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating and ventilation energy saving, in particular to a heating and ventilation energy saving heat exchange device. Background Art
[0002] The heat exchanger is a widely used heat exchange equipment, but scale forms inside the heat exchanger after a long time.
[0003] Scale is a solid substance formed by the crystallization of calcium and magnesium ions dissolved in water under high temperature conditions. The inevitable accumulation of scale hinders the heat transfer inside the heat exchanger, resulting in a decrease in heat exchange efficiency, increased energy consumption and operating costs, and changes in the flow rate inside the heat exchanger. Furthermore, scale creates an ideal environment for the growth of microorganisms. Microorganisms will form biofilms that accelerate the deposition of scale and clog the inside of the heat exchanger. In order to ensure the heat exchange efficiency of the heat exchanger and reduce energy consumption, the heat exchanger needs to be cleaned regularly, which will incur cleaning costs.
[0004] The existing methods for cleaning scale in heat exchangers are mainly through chemical reagents and manual physical cleaning. However, chemical reagents are inefficient in cleaning scale and cause chemical corrosion to the inside of the heat exchanger. Manual physical cleaning requires production suspension for cleaning and maintenance, which is time-consuming and labor-intensive.
[0005] Furthermore, an ultrasonic transducer is provided on the existing heat exchanger. By providing the ultrasonic transducer on the front end plate, scale formation is avoided by utilizing long-term vibration. Ultrasonic cleaning converts the signal emitted by the ultrasonic wave into high-frequency mechanical oscillation and transmits it to the water. However, the ultrasonic transducer is provided on the front end plate so that the high-frequency mechanical vibration is transmitted to the heat exchange plate through the front end plate, and then transmitted from the heat exchange plate to the water. However, many heat exchange plates are provided between the end plates, and the heat exchange plates in the middle or far from the ultrasonic transducer receive weaker mechanical vibrations, resulting in poor transmission efficiency and low efficiency in removing scale. Furthermore, some devices provide the ultrasonic transducer on the side of the heat exchange plate. However, when the ultrasonic transducer vibrates mechanically at high frequency, water leakage is unavoidable in the heat exchange plate during the long-term vibration process.
[0006] To this end, the utility model provides a HVAC energy-saving heat exchange device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Embodiment 1:
[0032] See also Figure 1-6 A HVAC energy-saving heat exchange device includes a supporting base plate 1, and also includes: a fixed component, a heat exchange component, a descaling component and a side inspection mechanism. The fixed component is arranged on the supporting base plate 1, the heat exchange component is arranged in the middle of the fixed component, the descaling component is arranged at both ends of the heat exchange component, and the side inspection mechanism is arranged between the supporting base plate 1 and the fixed component.
[0033] The fixing assembly includes a front end plate 21 and a bolt rod 25. The front end plate 21 is fixedly connected to the supporting base plate 1, and the bolt rod 25 is movably connected to the side ends of the front end plate 21 and the rear end plate 22 respectively.
[0034] A round rod 24 is movably connected to the front end plate 21 , and the round rod 24 is movably connected to the rear end plate 22 . A section of the round rod 24 away from the front end plate 21 is movably connected to a support column 23 .
[0035] The heat exchange assembly includes a cold outlet pipe 31, a hot inlet pipe 32, a cold inlet pipe 33 and a hot outlet pipe 34. The cold outlet pipe 31, the hot inlet pipe 32, the cold inlet pipe 33 and the hot outlet pipe 34 are connected at the side end of the front end plate 21. A heat exchange plate 35 is arranged between the front end plate 21 and the rear end plate 22. The upper and lower ends of the heat exchange plate 35 are slidably connected to the outside of the round rod 24. A heat exchange gasket 36 is fixedly connected to the heat exchange plate 35.
[0036] The descaling assembly includes a fixing plate 42, both ends of which are bolted to the side ends of the front end plate 21 and the rear end plate 22, and the side ends of the front end plate 21 and the rear end plate 22 are fixedly connected with shock-absorbing pads 41, and the outer side of the shock-absorbing pads 41 is tightly attached to the inner side of the fixing plate 42, and a plurality of ultrasonic transducers 43 are fixedly connected to the fixing plate 42.
[0037] A bottom side plate 51 is fixedly connected to the supporting bottom plate 1 , and a humidity sensor 52 is disposed on the bottom side plate 51 .
[0038] Working process: cold water is introduced into the cold outlet pipe 31 and hot water is introduced into the hot outlet pipe 34, so that the water flows through the heat exchange plate 35, and the water flows along the grooves on the heat exchange plate 35, so that the cold water and the hot water exchange heat, and the ultrasonic transducer 43 generates vibration and transmits it to the heat exchange plate 35 through the fixing plate 42. The heat exchange plate 35 transmits the high-frequency mechanical vibration into the water, and the water will produce relative tensile stress with the sound wave and then form a negative pressure. The negative pressure makes the gas originally dissolved in the water escape to form a number of tiny air bubbles. The air bubbles continue to vibrate under the action of the sound field. When the sound pressure reaches a certain value, the air bubbles will expand rapidly and then suddenly close. When the air bubbles are closed, a strong shock wave will be generated by the collision of the liquids, thereby forming thousands to tens of thousands of atmospheric pressures around them, so that the dirt can be easily removed. Then, the water flowing in from the hot inlet pipe 32 and the cold inlet pipe 33 will flush the fallen scale, and then the scale will be flushed out through the cold outlet pipe 31 and the hot outlet pipe 34 by the water flow.
[0039] After long-term use, the heat exchange plate 35 may inevitably leak due to mechanical vibration. The humidity sensor 52 detects the leakage and issues an alarm, thereby prompting manual maintenance in a timely manner.
