Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, specifically a heat pipe type fresh air handling unit. Background Technology

[0002] Current heat pipe-type fresh air handling units consist of an intake section and an exhaust section. The intake section is used to bring fresh outdoor air into the room, and the exhaust section is used to exhaust indoor air to the outside. A heat pipe connects the intake and exhaust sections. When fresh outdoor air enters the unit through the intake section, the heat pipe can absorb the heat (in winter) or cold (in summer) of the indoor air exhausted by the exhaust section and transfer it to the fresh air. In this way, the fresh air can be preheated in winter, reducing the energy consumption required for subsequent heating; in summer, the fresh air can be precooled, reducing the load on the air conditioning system and greatly improving energy efficiency.

[0003] The fresh air handling unit is equipped with a filter in the air intake section. The filter is used to filter dust and impurities in the outdoor air, preventing dust and impurities from entering and contacting the fan and heat pipes inside the duct. It protects the fan and heat pipes, reduces wear, and extends the service life of the equipment; ensures the heat exchange efficiency of the heat pipes, improves the air treatment effect; maintains indoor air quality, and protects human health. During long-term use, in order to prevent dust and impurities from clogging the filter, it is necessary to clean the filter regularly. The cleaning of the filter mainly relies on manual operation. Staff need to open the fresh air handling unit regularly to remove the filter for cleaning. This process not only consumes a lot of manpower and time, but also makes it difficult to guarantee the timeliness of cleaning.

[0004] While existing technologies include structures capable of cleaning filters, such as a heat pipe-type fresh air heat exchanger unit (publication number: CN117308345B), the cleaning structure used in this technology continuously vibrates and cleans the filter during use. This not only causes unnecessary energy waste but may also damage the filter structure due to excessive vibration, shortening its service life and thus limiting its capabilities.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Real-time detection and automatic cleaning of filter blockage are achieved through differential pressure triggering and mechanical linkage in the drive control component group. When dust accumulates on the filter, it slides backward under air pressure, triggering the sensor. The drive control component group reverses the fan blades in the fan blade section component group. At the same time, the filter body vibrates. The dust and impurities under the vibration of the filter body are blown to the outside by the airflow generated by the reversed fan blades, thus completing the maintenance and cleaning of the filter body. After the maintenance is completed, it returns to the initial working state under the control of the time relay and continues to draw fresh outdoor air into the room. In this technology, the maintenance of the filter body does not require manual intervention and can complete the cleaning work automatically. On the one hand, it reduces the labor cost of manual maintenance. On the other hand, it can automatically start cleaning when the filter is blocked, which can maintain it in time and ensure that the fresh air system is always in the best working state.

[0017] 2. In this application, the drive motor drives the fan blades through a transmission structure. During maintenance, the moving sleeve housing is moved by the electric telescopic rod, which switches the working state for maintenance. The switching operation is achieved by whether the clutch in the drive control component group is in contact with the positive friction clutch or the negative friction clutch. The drive motor used in the whole system can drive the air intake duct group to drive the air intake in daily. After switching the working mode, it can drive the filter body to vibrate through the transmission structure and drive the fan blades to reverse. This design achieves a high degree of functional integration and organic combination of drive and maintenance functions, making full use of equipment resources and improving energy efficiency.

[0018] 3. In the designed filter section component assembly, the rotation of the bottom column will drive the filter body to move back and forth at a high frequency in the inner sleeve installation tube. This high-frequency reciprocating movement will generate a vibration effect, causing dust and impurities on the filter to fall off. This structural design can achieve automatic cleaning, saving the work of manual disassembly and cleaning. Attached Figure Description

[0048] Working principle:

[0049] During normal operation of this heat pipe fresh air unit, the clutch 48 in the drive control assembly 40 is in the following state: one side of its friction plate is continuously in contact with the positive friction clutch 4111, thereby driving the motor 41 to rotate the spline shaft 42, spline sleeve 43, and synchronous pulley 45 through its working end. The rotation of synchronous pulley 45 drives the clutch 48 to rotate through the synchronous belt 46. The clutch 48, through friction, drives the positive friction clutch 4111, fan blade drive rod 4112, and fan blade drive rod 412. The 13 components rotate together, which in turn drives the fan blade component 33 to rotate through the fan blade transmission rod 4113. The operation of the fan blade component 33 allows air to enter the air intake duct assembly 100. Outdoor air will enter the room through the air intake duct assembly 100. The incoming air will be filtered by the filter body 13 in the air intake duct assembly 100. Over a long period of use, dust and impurities in the air will accumulate in the gaps of the filter body 13, forming a blockage. This reduces the airflow and affects the use of the fresh air system, thus requiring the filter body 13 to be cleaned.

[0050] The cleaning process can be started automatically. Firstly, dust and impurities clogging the filter body 13 will reduce airflow within the air intake duct assembly 100. The working fan blades 33 will still blow airflow to the right (e.g., ...). Figure 12As shown), at this time, the air intake duct assembly 100 is divided into left and right sections with the blocked filter body 13 as the center. The air in the right section is blown away by the fan blade 33, and the air pressure is low. The air in the left section is blocked by the filter body 13, and the air pressure is high. As a result, the filter body 13 will slide to the right under the action of the air pressure. When it slides to the bottom, it will contact the trigger end of the trigger sensor 415. The trigger sensor 415 will be triggered and send a signal to the time relay 413. The time relay 413 will receive the signal and start timing according to the preset time. During the timing process, the time relay 413 will control the electric telescopic rod 410 to retract, thereby driving the moving sleeve housing 44 to move in the direction of the electric telescopic rod 410. One end of the middle clutch 48 will release the friction contact with the positive friction clutch 4111, while the other end of the middle clutch 48 will make friction contact with the anti-friction clutch 4121. The operation of the drive motor 41 is driven by the middle clutch 48 and the front transmission rod 4122. The bottom column 164 rotates, and the rotating bottom column 164 causes the filter body 13 to reciprocate frequently within the groove of the inner sleeve mounting tube 12 via the convex column 163, connecting rod 162, and triangular connecting plate 161. During the high-frequency reciprocating movement of the filter body 13, dust and impurities on it begin to loosen and fall off under the action of vibration inertia. At the same time, the large gear ring 4123 on the anti-friction clutch 4121 drives the gear 4125 via the side transmission rod 4124. The rotation of gear 3 4125 will drive the positive friction clutch 4111, fan blade transmission rod 1 4112, fan blade transmission rod 2 4113 and fan blade 33 to rotate. Due to the transmission of rotation through the side transmission rod 4124 and the intermediate gear, the fan blade 33 will rotate in the opposite direction, and will then blow air towards the filter body 13. The air will carry the dust and impurities shaken off from the filter body 13 and discharge them to the outside, completing the cleaning of the filter body 13.

[0051] After the time relay 413 reaches the preset time, it will control the electric telescopic rod 410 to extend and reset. As the electric telescopic rod 410 extends, the moving sleeve housing 44 will move away from the electric telescopic rod 410, so that one end of the clutch 48 re-establishes frictional contact with the positive friction clutch 4111, while the other end releases frictional contact with the anti friction clutch 4121, thereby restoring the initial transmission state. At this time, the fan blade 33 also resumes forward rotation and continues normal air intake operation. The entire fresh air unit returns to a stable and efficient operating mode, continuously providing clean and fresh air to the room.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
