Description

Technical Field

[0001] This application relates to the technical field of air handling units, and in particular to an air handling unit insulation device. Background Technology

[0002] Air handling units, also known as air conditioning units or air handling cabinets, primarily rely on the rotation of fans to exchange heat between indoor air and the unit's internal coils, while also filtering impurities from the air. This controls the outlet air temperature and airflow to maintain indoor temperature, humidity, and air cleanliness. Air handling units with fresh air intake functions also provide heat and humidity treatment and filtration for both fresh and return air.

[0003] Currently, our company has developed and produced a small household air handling unit, as announced in CN222670195U. It includes a cabinet assembly, an air outlet on the top wall of the cabinet assembly, a surface cooler at the bottom of the cabinet assembly, an air inlet on the top of the cabinet assembly, the central axes of the air inlet and the air outlet are not on the same straight line, a fan assembly between the surface cooler and the air outlet, and several mounting plates for installing various functional components inside the cabinet assembly.

[0004] Regarding the aforementioned technologies, the inventors discovered that the cabinet assembly comprises a frame and insulation panels disposed on various surfaces of the frame. The frame is constructed from several square tubes joined together. However, when the insulation panels are located at the corners of these square tubes, gaps still form between adjacent insulation panels, causing the square tubes to come into contact with external air. This results in poor heat insulation and negatively impacts the normal air handling performance of the internal functional components. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides an air handling unit insulation device, which has the advantages of reducing heat transfer between the square tube and the outside, thereby ensuring the insulation effect and thus ensuring the normal functioning of the air handling unit.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: An air handling unit insulation device includes insulation frames disposed on each side of the unit frame, and insulation boards disposed between the insulation frames; The insulation frame includes interlocking insulation panels, each insulation panel comprising a transverse insulation section and a longitudinal insulation section, the transverse insulation section and the longitudinal insulation section being attached to adjacent side walls of the frame. Each of the two adjacent insulation frames has a sealing strip on its exposed outer side to seal the gap between them.

[0007] To achieve the above technical solution, the frame is insulated on all sides by insulation frames and insulation boards, ensuring accurate and controllable heat exchange of the air handling system inside the frame. The four sides of the square tube are wrapped by the transverse and longitudinal insulation sections of two adjacent insulation boards, thus ensuring insulation of the square tube and reducing heat conduction between the square tube and the outside. The two ends of the square tube are directly covered by the insulation frames at both ends, thereby ensuring the insulation effect. To prevent external air from contacting the square tube through the gap between the two insulation frames, decorative sealing strips are installed on the exposed side of the two adjacent insulation frames to seal the gap, thereby further ensuring the insulation effect.

[0008] As a preferred embodiment of this application, both the transverse insulation section and the longitudinal insulation section are provided with a plurality of hollow heat insulation cavities.

[0009] The above technical solution enables the hollow insulation cavity to be filled with air, which is an inert thermally conductive material and does not flow inside, thus ensuring the insulation effect.

[0010] As a preferred embodiment of this application, a portion of the hollow insulation cavity is provided with locking screws for screwing the insulation plate onto the square tube of the machine frame.

[0011] The above technical solution enables the locking screw to fulfill its locking function. It is located inside the hollow insulation cavity and is not in contact with the outside world. This prevents the square tube from transferring heat to the outside world through the locking screw, thus ensuring the insulation effect.

[0012] As a preferred embodiment of this application, the transverse insulation section is provided with an inner sealing groove on the side near the square tube, and a sealant is provided between the inner sealing groove and the square tube.

[0013] The above technical solution enables the horizontal insulation section and the square tube to be sealed with sealant, thereby preventing the entry of external air.

[0014] As a preferred embodiment of this application, an inner sealing protrusion is provided on the inner wall of the inner sealing groove.

[0015] The above technical solution ensures the tightness of the sealant adhesion.

[0016] As a preferred embodiment of this application, the insulation frame is covered with a protective shell, the end of the protective shell is provided with a folded edge folded inward toward the insulation frame, and the end of the transverse insulation part is provided with a positioning platform for the folded edge to be embedded and positioned.

[0017] The above technical solution enables the protective shell to protect the insulation frame, while the folded edge design ensures comprehensive protection, and the positioning platform ensures the flushness of the folded edge without protrusion, thus guaranteeing the sealing effect of the subsequent decorative sealing strip.

[0018] As a preferred embodiment of this application, the top of the transverse insulation section is provided with a plurality of external sealing grooves arranged along the direction close to the insulation board, the inner wall of the external sealing groove is provided with a plurality of external sealing protrusions, and a sealant is provided between the external sealing groove and the insulation board.

[0019] The above technical solution is achieved by injecting sealant into the outer sealing groove to ensure sealing and thus guarantee the thermal insulation effect.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The insulation of each surface of the frame is achieved through insulation frames and insulation boards, ensuring accurate and controllable heat exchange of the air handling system inside the frame. The four sides of the square tube are wrapped by the transverse and longitudinal insulation sections of two adjacent insulation boards, thus ensuring insulation of the square tube and reducing heat conduction between the square tube and the outside. The two ends of the square tube are directly covered by the insulation frames at both ends, further ensuring the insulation effect. To prevent external air from contacting the square tube through the gap between the two insulation frames, decorative sealing strips are installed on the exposed side of the two adjacent insulation frames to seal the gap, thereby further ensuring the insulation effect.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses an air handling unit insulation device. (Refer to...) Figure 1 The air handling unit insulation device includes insulation frames 2 installed on each side of the frame 1, and insulation boards 3 are installed between the insulation frames 2; that is, the insulation frames 2 and insulation boards 3 are used to insulate each side of the frame 1 to ensure accurate and controllable heat exchange of the air handling system inside the frame 1.

[0028] The insulation frame 2 includes interlocking insulation panels 21, each comprising a transverse insulation section 211 and a longitudinal insulation section 212. The transverse and longitudinal insulation sections 211 and 212 are attached to adjacent side walls of the frame 1. This ensures that the four sides of the square tube 11 of the frame 1 are enclosed by the transverse and longitudinal insulation sections 211 and 212 of adjacent insulation panels 21, thereby guaranteeing insulation of the square tube 11 and reducing heat conduction between the square tube 11 and the outside. The two ends of the square tube 11 are directly covered by the insulation frames 2 at both ends, further ensuring insulation performance. To prevent external air from contacting the square tube 11 through the gap between the two insulation frames 2, decorative sealing strips 22 are provided on the exposed outer side of adjacent insulation frames 2 to seal the gap, further ensuring insulation performance.

[0029] In order to ensure the insulation effect of the insulation board 21, both the transverse insulation part 211 and the longitudinal insulation part 212 are provided with a number of hollow insulation cavities 213. The hollow insulation cavity 213 is designed to be filled with air. Since air is an inert thermal conductive material and does not flow inside, the insulation effect is guaranteed.

[0030] To ensure the stability of the insulation board 21, a portion of the hollow insulation cavity 213 is equipped with locking screws 4 for screwing the insulation board 21 onto the square tube 11. These locking screws 4, while fulfilling their locking function, are located inside the hollow insulation cavity 213 and are not in contact with the outside, thus preventing heat transfer from the square tube 11 to the outside environment and ensuring the insulation effect. The top of the hollow insulation cavity has mounting holes for installing the locking screws 4. A sealing cap (not shown in the figure) can be inserted into these holes to seal them, ensuring both ease of installation and effective insulation.

[0031] An inner sealing groove 214 is provided on the side of the transverse insulation section 211 near the square tube 11, and sealant (not shown in the figure) is provided between the inner sealing groove 214 and the square tube 11. This sealant allows the transverse insulation section 211 and the square tube 11 to be sealed, preventing external air from entering. An inner sealing protrusion 215 is provided on the inner wall of the inner sealing groove 214 to ensure the tightness of the sealant adhesion.

[0032] To prevent damage to the insulation frame 2 and insulation board 3 from external objects, a protective shell 5 is provided on the outside of the insulation frame 2. The end of the protective shell 5 is provided with a folded edge 51 that folds inward toward the insulation frame 2, and the end of the transverse insulation part 211 is provided with a positioning platform 216 for the folded edge 51 to be embedded and positioned. Thus, the protective shell 5 protects the insulation frame 2, while the folded edge 51 ensures comprehensive protection, and the positioning platform 216 ensures the flushness of the folded edge 51 and prevents it from protruding, thereby ensuring the sealing effect of the subsequent decorative sealing strip 22.

[0033] To prevent external air from entering through the gap between the protective shell 5 and the insulation board 21, the top of the transverse insulation section 211 is provided with several external sealing grooves 217 arranged along the direction close to the insulation board 3. Several external sealing protrusions 218 are provided on the inner wall of the external sealing grooves 217, and sealant is provided between the external sealing grooves 217 and the insulation board 3. That is, the sealing performance is ensured by injecting sealant into the external sealing grooves 217, thereby ensuring the insulation effect.

[0034] The implementation principle of the air handling unit insulation device in this application embodiment is as follows: the insulation frame 2 and the insulation board 3 insulate the various surfaces of the frame 1 to ensure accurate and controllable heat exchange of the air handling base inside the frame 1; the four sides of the square tube 11 can be wrapped by the transverse insulation part 211 and the longitudinal insulation part 212 of the two adjacent insulation boards 21, thereby ensuring the insulation of the square tube 11 and reducing the heat conduction between the square tube 11 and the outside; the two ends of the square tube 11 can be directly covered by the insulation frames 2 at both ends, thereby ensuring the insulation effect; in order to prevent the outside air from contacting the square tube 11 through the gap between the two insulation frames 2, a decorative sealing strip 22 is provided on the exposed side of the two adjacent insulation frames 2 to seal the gap between them, that is, the decorative sealing strip 22 seals and isolates the gap, thereby further ensuring the insulation effect.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
