Description

Technical Field

[0002] The trilobal heat exchanger was born out of people's urgent need for efficient use of heat energy. In the past, a lot of heat was often wasted in industrial production or daily heating due to the dispersion of equipment and poor heat transfer, which increased costs and polluted the environment. Heat exchangers concentrate heat and realize the rapid exchange of hot and cold media, allowing waste heat to be recovered and reused. For example, the heat in factory waste liquid can be used to heat domestic water. It has a compact structure and flexible installation, which can be adapted to different scenarios. It helps enterprises save energy expenses and reduce carbon emissions, becoming an indispensable "heat transporter" in modern energy conservation and environmental protection, allowing every bit of heat energy to play a greater role.

[0003] Traditional trilobal heat exchangers only facilitate rapid exchange of hot and cold media. However, these media often contain various impurities. Prolonged use of media with impurities can cause blockages inside the trilobal heat exchanger, affecting its performance and increasing maintenance costs. Therefore, a new trilobal heat exchanger is proposed. Utility Model Content

[0027] like Figure 1 As shown, this embodiment proposes a three-lobe heat exchanger, including a base plate 1, a filter assembly 2 for filtering the liquid undergoing heat exchange, and an anti-scaling assembly 3 for preventing liquid condensation and scale damage to the device.

[0028] like Figure 4 and Figure 5 As shown, the filter assembly 2 includes two filter boxes 201 fixedly installed on the top of the base plate 1. The filter boxes 201 are used to contain liquid. A three-lobe heat exchanger body 202 is provided on the top of the base plate 1. The three-lobe heat exchanger body 202 is used for heat exchange. Water inlet pipes 203 are fixedly connected to both sides of the three-lobe heat exchanger body 202, and water outlet pipes 204 are fixedly connected to both sides of the three-lobe heat exchanger body 202. The end of the water inlet pipe 203 away from the three-lobe heat exchanger body 202 is fixedly connected to one side of the filter box 201. Two slots 205 are provided on the top of the filter box 201. The slots 205 are used to facilitate the replacement of the filter plate 206 by the user. The filter plate 206 is engaged inside the slots 205. The filter plate 206 is used to filter out impurities in the liquid. An observation window 207 is fixedly installed on the filter box 201. The observation window 207 is used to allow users to easily understand the situation inside the filter box 201. A speed-controlled water pump 208 is installed around the water inlet pipe 203. The speed-controlled water pump 208 is used to control the flow rate of the liquid for heat exchange. In use, the liquid to be heat exchanged is input into the three-lobe heat exchanger body 202 through the water inlet pipe 203 to carry out heat exchange. The filter plate 206 can filter out particulate impurities in the liquid to avoid clogging. The filter plate 206 can be easily removed and replaced through the slot 205. The observation window 207 allows users to easily understand the filtration status of the filter plate 206 and the impurities inside the filter box 201. The speed-controlled water pump 208 can control the flow rate of the liquid for heat exchange, allowing users to use it flexibly according to the situation.

[0029] like Figure 5As shown, the anti-scaling component 3 includes a servo motor 301 fixedly installed on the top of the filter box 201. The servo motor 301 provides power, and a stirring rod 302 is fixedly installed at the output end of the servo motor 301. Several stirring plates 303 are welded to the periphery of the stirring rod 302. The servo motor 301 drives the stirring rod 302 and stirring plates 303 to rotate and stir. An additive box 304 is fixedly installed on the top of the filter box 201. The additive box 304 is used to hold scale inhibitors. An electric control valve 305 is provided on the periphery of the additive box 304. The electric control valve 305 is used to uniformly add scale inhibitors. During use, chemical scale inhibitors such as polyphosphates can be added to the additive box 304 as needed to prevent scale formation inside the trilobal heat exchanger body 202. The additive can be added to the filter box 201 in a timed and quantitative manner through the electric control valve 305. The servo motor 301 provides power to drive the stirring rod 302 and stirring plates 303 to rotate, so as to stir the additive evenly and ensure the effect of the additive.

[0030] like Figure 3 As shown, temperature sensors 4 are installed inside both the outlet pipe 204 and the inlet pipe 203. A control panel 5 is fixedly installed on one side of the tri-lobe heat exchanger body 202. A display screen 6 is installed on the side of the control panel 5 away from the tri-lobe heat exchanger body 202. During use, the temperature sensors 4 record the temperature of the liquid entering and exiting the system and display it on the display screen 6, allowing the user to easily understand the liquid temperature. The speed of the speed-controlled water pump 208 can be adjusted through the controller. During maintenance, the user can use a computer to calculate the device's operating efficiency based on the changes in liquid temperature during entry and exit, combined with the flow rate. When the device's operating efficiency differs significantly from the factory operating efficiency, the user can perform comprehensive maintenance to troubleshoot the problem.

[0031] like Figure 3 As shown, a receiving chamber 7 is welded to the top of the base plate 1. The position of the receiving chamber 7 corresponds to the position of the three-lobe heat exchanger body 202. Several partition plates 8 are welded inside the receiving chamber 7. During use, when the three-lobe heat exchanger is damaged and a small leak occurs, the leaked liquid will collect inside the receiving chamber 7. Users can judge whether the device is leaking by periodically observing the condition inside the receiving chamber 7. The receiving chamber 7 can be divided into partitions by the partition plates 8. When leaked liquid collects in a certain area, it indicates that there is a leak point above it, which makes it easy for users to locate the leak area.

[0032] like Figure 3As shown, a soundproof cover 9 is fixedly installed on the top of the base plate 1. The position of the soundproof cover 9 corresponds to the position of the three-lobe heat exchanger body 202. A noise reduction layer 13 is fixedly connected inside the soundproof cover 9. The noise reduction layer 13 is made of glass wool. When in use, noise reduction is achieved through the noise reduction layer 13 during device operation to reduce the noise generated by the device operation. Glass wool can absorb sound wave energy and reduce reflection, resulting in good noise reduction effect.

[0033] like Figure 4 As shown, a conductive plate 10 is fixedly connected to one side of the three-lobe heat exchanger body 202. A grounding wire 11 is fixedly connected to the conductive plate 10. The outer surface of the conductive plate 10 is coated with conductive paste. During use, static electricity will be generated during the operation of the device. When the liquid being heat exchanged is a flammable liquid, there will be a safety hazard. The static electricity can be conducted through the conductive plate 10 and eliminated through the grounding wire 11, thereby reducing the safety hazard.

[0034] like Figure 5 As shown, the top of the filter box 201 is provided with two sealing gaskets 12, which correspond to the position of the filter plate 206. In use, the sealing gaskets 12 can enhance the sealing of the filter box 201 and prevent liquid leakage.

[0035] Specifically, in use, the liquid to be exchanged is introduced into the body 202 of this trilobal heat exchanger through the inlet pipe 203. The filter plate 206 filters out particulate impurities in the liquid, preventing clogging. The filter plate 206 can be easily removed and replaced through the slot 205. The observation window 207 allows the user to easily monitor the filtration status of the filter plate 206 and the filter box 201. The speed-controlled water pump 208 controls the flow rate of the liquid undergoing heat exchange, allowing the user to use it flexibly according to the situation (e.g., ...). Figure 4 and Figure 5 As shown), chemical scale inhibitors such as polyphosphates can be placed in the additive box 304 as needed to prevent scale formation inside the trilobal heat exchanger body 202. The additive can be added to the filter box 201 at regular intervals and in measured quantities via the electrically controlled valve 305. The servo motor 301 provides power to rotate the stirring rod 302 and stirring plate 303, ensuring the additive is evenly mixed and guaranteeing its effectiveness. Figure 5 As shown), temperature sensor 4 records the temperature of the liquid entering and exiting, and displays it on display screen 6, allowing users to easily understand the liquid temperature. The speed of the speed-controlled water pump 208 can be adjusted via the controller. During maintenance, users can use a computer to calculate the device's operating efficiency based on the changes in liquid temperature during entry and exit, combined with the flow rate. When the device's operating efficiency differs significantly from its factory operating efficiency, users can perform comprehensive maintenance to troubleshoot the problem (e.g., ...). Figure 3 (As shown).
