Description

Technical Field

[0001] The utility model relates to ventilation equipment, in particular to a heat exchange module with a filtering function. Background Art

[0002] As an important heat energy conversion device, heat exchangers are widely used in ventilation, air conditioning, and heat recovery. Ceramic heat exchangers, in particular, have become a common type of heat exchanger on the market due to their excellent heat transfer performance and good high-temperature resistance. However, in existing technologies, ceramic heat exchangers still have some obvious defects and shortcomings during use, mainly including the following aspects:

[0003] 1. Lack of efficient filtration, resulting in ineffective air quality assurance: Existing ceramic heat exchanger structures typically focus solely on efficient heat transfer while neglecting air quality control. In practice, heat exchangers are often used in ventilation systems, where the air may contain various tiny particles and pollutants. Existing heat exchangers lack effective filtration mechanisms, preventing the removal of impurities from the air entering the heat exchanger, which may eventually enter the room during the heat exchange process. This not only affects air quality but also contaminates the heat exchanger interior, reducing heat exchange efficiency. Furthermore, the lack of a suitable filtration device allows pollutants to accumulate during the heat exchange process, further impacting the long-term stability and performance of the heat exchanger.

[0004] 2. The connection structure between the filter and the heat exchange core is unreasonable, making maintenance difficult: Although some existing technologies have added filtering devices to heat exchangers, the filter fixing method is often too simple. For example, the filter is usually directly attached to the inside of the heat exchanger by snapping or gluing. This installation method is not only not strong enough, but also prone to loosening or even falling off during long-term use due to high temperature and humidity fluctuations. In addition, these simple installation methods can also cause great inconvenience when cleaning or replacing, increasing maintenance costs and labor intensity. Especially in industrial applications, frequent maintenance and cleaning needs have a negative impact on the operating efficiency and maintenance costs of equipment.

[0005] 3. Inadequate integrated design for heat exchange and filtration functions leads to low equipment efficiency: In existing heat exchanger structures, the heat exchange core and filter are typically separated. This design forces air to flow through different components during filtration and heat exchange, increasing air flow resistance and reducing overall ventilation efficiency. Furthermore, the lack of compactness makes the entire device bulky, making it unsuitable for use in applications with limited space. Furthermore, this separate design results in a complex air flow path, which can easily lead to uneven flow, further compromising heat exchange and the overall energy efficiency of the equipment.

[0006] 4. Lack of a fast disassembly and assembly fixing structure, inconvenient installation and maintenance: The current connection structure between the heat exchanger and the shell mostly adopts traditional fixing methods such as bolts or welding, which makes on-site installation and maintenance time-consuming and labor-intensive. For example, when it is necessary to clean the interior or replace the filter, the entire device needs to be completely disassembled, which not only increases the difficulty of maintenance, but may also cause damage to the equipment. The lack of a quick disassembly and assembly design makes the operating experience of the equipment poor and reduces the user's convenience. Especially in scenarios that require rapid response, such as industrial production lines or air-conditioning systems that require frequent maintenance, this traditional fixing method is very inflexible and cannot meet the needs of rapid replacement and efficient maintenance. Therefore, it is necessary to make further improvements to it. Utility Model Content

[0025] The present invention is further described below in conjunction with the accompanying drawings. A heat exchange module with a filtering function comprises a heat exchange inner liner 1 and a heat exchange outer shell 2 encased therein. The heat exchange outer shell 2 is connected to a ventilation duct 3. A ceramic heat exchange core 4 is fixedly mounted within the heat exchange inner liner 1. The ceramic heat exchange core 4 is axially provided with a plurality of heat exchange holes 41 through which air is passed for heat exchange. Filters 5 are mounted on both ends of the ceramic heat exchange core 4.

[0026] In one embodiment, the filter 5 is fixed to the inner hole of the heat exchange liner 1 through a mounting bracket.

[0027] In one embodiment, the mounting bracket includes a positioning ring 6 and a plurality of reinforcing ribs 61 disposed inside the positioning ring, and the filter 5 covers one side of the reinforcing ribs 61 .

[0028] In one embodiment, the reinforcing ribs 61 are arranged in a cross-shaped distribution, and the reinforcing ribs 61 and the positioning ring 6 are formed integrally.

[0029] In one embodiment, the filter 5 is filter cotton.

[0030] In one embodiment, the filter 5 is a HEPA high efficiency filter.

[0031] In one embodiment, a fixed panel 7 is provided at the bottom of the heat exchange shell 2, and the fixed panel 7 is connected to a fixed object to fix the heat exchange shell 2. An air outlet panel 8 is provided at the bottom of the heat exchange liner 1, and the air outlet panel 8 is covered in the fixed panel 7. The air outlet panel 8 and the fixed panel 7 are connected by a quick release mechanism.

[0032] In one embodiment, the quick-release mechanism is a mounting hole 81 provided on the air outlet panel 8 and a screw hole 71 provided on the fixed panel 7 , and the fixing screw passes through the mounting hole 81 and is fixed to the screw hole 71 .

[0033] In one embodiment, the quick-release mechanism is a plurality of annularly distributed clamping platforms 72 provided on the fixed panel 7 and a plurality of clamping slots 82 provided on the air outlet panel 8. The air outlet panel 8 is fixed in the clamping platforms 72 by snapping into the clamping slots 82.

[0034] Working principle: This heat exchange module with filtering function is a device that integrates air heat exchange and filtering functions. It is designed with a structure that separates the inside and outside and the inner liner is detachable, which is convenient for users to clean or replace consumables.

[0035] When air enters the heat exchange module through ventilation duct 3, it first enters heat exchange shell 2 and then heat exchange liner 1. A ceramic heat exchange core 4 is fixed within the heat exchange liner. This core has multiple axially arranged heat exchange holes 41. As air flows through these holes, it exchanges heat with the ceramic heat exchange core. Ceramic materials have excellent thermal conductivity and can quickly absorb and release heat from the flowing air.

[0036] If the incoming air is cold, the heat exchange core absorbs the heat from its previously stored energy and transfers it to the cold air, thereby heating it. If the incoming air is hot, the heat is transferred back to the heat exchange core, cooling it. This heat exchange mechanism helps save energy and reduces energy waste caused by the temperature difference between indoor and outdoor.

[0037] Before and after the air flows through the ceramic heat exchange core 4, it passes through filters 5 installed at both ends of the heat exchange core. The filters can filter out particulate matter in the air, such as dust, smoke and pollen, ensuring that the air entering the room is not only heat exchanged but also purified.

[0038] The filter can be either a cotton filter or a HEPA filter. Cotton filters are suitable for use in environments with general air quality requirements, filtering out larger particles of pollutants. HEPA filters, on the other hand, can capture particles as small as 0.3 microns and are suitable for environments with high air cleanliness requirements, such as hospitals and laboratories.

[0039] It's important to note that this heat exchange module features a detachable design, allowing users to easily remove the heat exchanger liner via a quick-release mechanism. To do this, simply loosen the screws between the air outlet panel and the mounting panel and rotate counterclockwise to remove the liner from the heat exchanger housing. After removing the liner, users can clean or replace the filter 5 to maintain efficient operation.

[0040] Compared to traditional technologies, this new device integrates air heat exchange and filtration functions into a single device, achieving simultaneous air purification while exchanging heat. This not only improves air quality but also increases energy efficiency and reduces heat loss, making it particularly suitable for air conditioning and ventilation systems in modern buildings. The ceramic material of the heat exchange core ensures efficient heat transfer, thereby improving the energy efficiency of the entire system.

[0041] Furthermore, the module features a separate internal and external heat exchanger design, with the heat exchanger liner and outer shell existing independently. The outer shell can be fixed to the ceiling or wall, allowing users to remove the liner with a simple operation without disassembling the outer shell or piping system. This design greatly simplifies maintenance, especially for fixed equipment that is difficult to disassemble, reducing operational complexity.

[0042] The removable inner liner allows for quick and easy maintenance. Using a quick-release mechanism, users simply unscrew and rotate the inner liner to remove and replace filters or clean internal consumables. This design significantly reduces the time and effort required to replace consumables, making device maintenance possible without the need for specialized personnel, significantly improving the user experience.

[0043] Furthermore, the tight integration of the liner and outer shell ensures excellent airtightness. Even with the removable liner, air cannot leak through the heat exchange module, ensuring efficient heat exchange and air filtration. This airtight design not only improves energy efficiency but also effectively prevents unfiltered air from entering the room, improving air quality.

[0044] In summary, this heat exchange module with filtration, through its innovative design of internal and external separation and removable liner, not only achieves efficient air heat exchange and filtration, but also greatly simplifies equipment maintenance and cleaning. Its simple assembly and disassembly, rapid consumable replacement, excellent airtightness, and flexible filter selection make it an energy-efficient, easy-to-maintain air handling device suitable for a variety of applications, making it suitable for widespread use.
