Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically a heat transfer fluid recovery and circulation system. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. It plays an important role in chemical, petroleum, power, food and many other industrial productions. The heat transfer fluid is an important circulating medium in the heat exchanger, used to carry heat from a high temperature region to a low temperature region, and then recirculate it after heat exchange in the low temperature region.

[0003] The existing heat transfer fluid recovery and circulation devices have the following drawbacks during use: During long-term circulation of the heat transfer fluid, a lot of impurities are easily generated in the heat transfer fluid. These impurities mix in the heat transfer fluid and adhere to the inner wall of the heat exchanger pipes as the heat transfer fluid circulates, causing blockage of the circulation channels in the heat exchanger. It is necessary to disassemble the heat exchanger for cleaning, which is troublesome, time-consuming and labor-intensive. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a heat transfer fluid recovery and circulation system, including: a main body and a filtration mechanism. The main body includes a heat exchange plate, heat dissipation components symmetrically fixed on both sides of the heat exchange plate, a shell symmetrically arranged on both sides of the heat exchange plate and communicating with the inner cavity of the heat exchange plate, a movable seat movably arranged in the inner cavity of the shell, a tube body with one end fixed to the top of the movable seat and the other end extending out of the shell, a drive component installed on one side of the heat exchange plate and fixedly connected to the tube body, and a pump arranged on one side of the heat exchange plate and communicating with one side of the shell.

[0006] The movable seat has a direct current channel at one end and an L-shaped flow channel at the other end, with one end of the L-shaped flow channel connected to the tube body.

[0007] The filtration mechanism includes a cylinder disposed on one side of the housing and communicating with the inner cavity of the housing, a filter cartridge fixed on the inner wall of the cylinder, a recovery pipe with one end communicating with the inner cavity of the filter cartridge and the other end extending out of the cylinder, and a sealing plug installed at the bottom of the cylinder by a threaded connection.

[0008] In a preferred embodiment, the present invention can be further configured such that the inner cavity of the heat exchange plate is provided with a serpentine flow channel, and the two ends of the serpentine flow channel are respectively connected to the inner cavities of the shell on both sides.

[0009] In a preferred embodiment, the present invention can be further configured such that the heat sink includes heat dissipation fins fixed in an array on one side of the heat exchange plate and a high-speed fan fixed on one side of the heat dissipation fins.

[0010] In a preferred embodiment, the present invention can be further configured such that the driving component includes an electric telescopic rod fixed to one side of the heat exchange plate and a connecting plate with one end fixed to the end of the electric telescopic rod and the other end fixedly sleeved on the outside of the tube body.

[0011] In a preferred embodiment, the present invention can be further configured such that: the inlet of the pump is connected to the inner cavity of one side of the housing via a connecting pipe, the outlet is provided with an output pipe, and a flow sensor is installed on the connecting pipe.

A straight channel and an L-shaped channel are provided in the movable seat. When the serpentine flow channel in the heat exchange plate is blocked, the driving component drives the movable seat to move down, so that the end of the L-shaped flow channel is aligned with the end of the serpentine flow channel. At this time, high-pressure water flows into the movable seat through one side of the tube and enters the serpentine flow channel under the action of the L-shaped flow channel, washing away the dirt and impurities attached to the inner wall of the serpentine flow channel. The waste liquid generated by washing is discharged through the other side of the tube, realizing automatic cleaning of dirt on the inner wall of the heat exchange plate without disassembling the heat exchange plate, effectively increasing the practical performance.

A filter cartridge is provided in the inner cavity of the cylindrical body, and a recovery pipe communicating with the top of the filter cartridge is installed on the cylindrical body. With the above arrangement, when the heat transfer fluid flows back through the recovery pipe, it enters the filter cartridge. The filter cartridge can effectively filter impurities and dirt in the heat transfer fluid. Then the heat transfer fluid enters the inner cavity of the shell and enters the heat exchange plate through the direct flow channel on the movable seat for heat exchange. It can filter the heat transfer fluid before it enters the heat exchange plate, reducing the probability of impurities and dirt in the heat transfer fluid entering the heat exchange plate and causing blockage of the serpentine flow channel, and further increasing the practical performance.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0024] Example 1:

[0025] Combination Figure 1-4 As shown, this embodiment provides a heat transfer fluid recovery and circulation system, including: a main body 100 and a filtration mechanism 200.

[0026] The main structure 100 includes a heat exchange plate 110, heat dissipation components 120 symmetrically fixed on both sides of the heat exchange plate 110, a housing 130 symmetrically arranged on both sides of the heat exchange plate 110 and communicating with the inner cavity of the heat exchange plate 110, a movable seat 140 movably arranged in the inner cavity of the housing 130, a tube 150 with one end fixed to the top of the movable seat 140 and the other end extending out of the housing 130, a drive component 160 installed on one side of the heat exchange plate 110 and fixedly connected to the tube 150, and a pump 170 arranged on one side of the heat exchange plate 110 and communicating with one side of the housing 130.

[0027] The heat exchange plate 110 has a serpentine flow channel 111 inside for the heat transfer fluid to pass through, and to prolong the flow time of the heat transfer fluid in the heat exchange plate 110, so that the heat in the heat transfer fluid can be fully transferred to the heat dissipation component 120 through the heat exchange plate 110.

[0028] The heat sink 120 is used for heat dissipation, including heat sink fins 121 fixed in an array on one side of the heat exchange plate 110 and a high-speed fan 122 fixed on one side of the heat sink fins 121. The heat sink fins 121 are used to increase the heat dissipation area so that more heat can be carried away when the air passes through. The high-speed fan 122 can effectively increase the airflow speed near the heat sink fins 121 and increase the heat dissipation efficiency.

[0029] The housing 130 is used to mount the movable seat 140. Both ends of the serpentine flow channel 111 are connected to the inner cavities of the housing 130 on both sides. The movable seat 140 is fitted into the inner cavity of the housing 130. A direct flow channel 141 is provided at one end of the movable seat 140 to facilitate the entry of heat transfer fluid into the serpentine flow channel 111 and to facilitate the discharge of cooled heat transfer fluid. An L-shaped flow channel 142 is provided at the other end for high-pressure water to enter the serpentine flow channel 111. One end of the L-shaped flow channel 142 is connected to the pipe body 150. This configuration allows for easy adjustment of the serpentine flow channel 111 when necessary. When cleaning the inner wall of heat exchange plate 110, the drive unit 160 drives the tube body 150 to move down, and the tube body 150 moves down, causing the movable seat 140 to move down, so that the end of the L-shaped flow channel 142 is aligned with the end of the serpentine flow channel 111. At this time, high-pressure water flows through one side of the tube body 150 into the movable seat 140, and under the action of the L-shaped flow channel 142, it enters the serpentine flow channel 111 to wash away the dirt and impurities attached to the inner wall of the serpentine flow channel 111. The waste liquid generated by washing is discharged through the other side of the tube body 150, realizing the automatic cleaning of dirt on the inner wall of heat exchange plate 110.

[0030] The driving component 160 is used to move the tube body 150 and the movable seat 140. It includes an electric telescopic rod 161 fixed to one side of the heat exchange plate 110 and a connecting plate 162 with one end fixed to the end of the electric telescopic rod 161 and the other end fixedly sleeved on the outside of the tube body 150. When the electric telescopic rod 161 is started, it drives the tube body 150 to move synchronously through the connecting plate 162.

[0031] The inlet of pump 170 is connected to the inner cavity of one side housing 130 through connecting pipe 171, which facilitates the entry of the cooled heat transfer liquid into pump 170. The outlet is provided with an outlet pipe 172, which is used to pump out the cooled heat transfer liquid again. A flow sensor 1711 is installed on the connecting pipe 171 to monitor the flow rate of the heat transfer liquid in the connecting pipe 171 in real time.

[0032] The filtration mechanism 200 is used to filter impurities and dirt in the heat transfer fluid. It includes a cylinder 210 disposed on one side of the housing 130 and communicating with the inner cavity of the housing 130, a filter cartridge 220 fixed on the inner wall of the cylinder 210, a recovery pipe 230 with one end communicating with the inner cavity of the filter cartridge 220 and the other end extending out of the cylinder 210, and a sealing plug 240 installed at the bottom of the cylinder 210 by a threaded connection.

[0033] One side of the cylinder 210 is connected to the inner cavity of the shell 130 through a pipe, which facilitates the entry of the filtered heat transfer liquid into the inner cavity of the shell 130. The filter cartridge 220 is used to filter impurities and dirt in the heat transfer liquid to prevent them from entering the serpentine flow channel 111. The recovery pipe 230 is used to guide the returned heat transfer liquid into the filter cartridge 220. The sealing cap is installed at the bottom of the cylinder 210 through a threaded connection. When there are many impurities in the filter cartridge 220, the sealing plug 240 can be unscrewed to clean the impurities in the filter cartridge 220.

[0034] The working principle and usage process of this utility model are as follows: During use, the returned heat transfer fluid enters the filter cartridge 220 through the recovery pipe 230. The filter cartridge 220 filters impurities and dirt from the heat transfer fluid. The filtered heat transfer fluid then enters the housing 130 and flows through the direct current channel 141 on the movable seat 140 into the serpentine flow channel 111 within the heat exchange plate 110. The high-temperature heat transfer fluid flows through the serpentine flow channel 111, and heat is transferred through the heat exchange plate 110 to the heat dissipation fins 121. Simultaneously, the high-speed fan 122 starts, increasing the airflow velocity near the heat dissipation fins 121 and the heat exchange plate 110, allowing the air to quickly remove heat from the heat exchange plate 110 and the heat dissipation fins 121, thus cooling the heat transfer fluid. The cooled heat transfer fluid then flows through the direct current channel 141 on the other side of the movable seat 140. The heat transfer fluid is sent out through pipe 141 and enters pump 170 through connecting pipe 171. Then, pump 170 pumps the cooled heat transfer fluid out again through output pipe 172 to form a cycle. In addition, when it is necessary to clean the inner cavity of the serpentine flow channel 111, the electric telescopic rods 161 on both sides are started simultaneously, driving the movable seat 140 to move down, so that the end of the L-shaped flow channel 142 is aligned with the end of the serpentine flow channel 111. At this time, the high-pressure water flow enters the movable seat 140 through one side pipe 150 and enters the serpentine flow channel 111 under the action of the L-shaped flow channel 142, washing away the dirt and impurities attached to the inner wall of the serpentine flow channel 111. The waste liquid generated by washing is discharged through the other side pipe 150, completing the cleaning. After the cleaning is completed, the electric telescopic rod 161 drives the movable seat 140 to reset.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
