Description

Technical Field

[0001] The present invention relates to the field of fresh air equipment, and in particular to a full heat exchange core and a fresh air fan suitable for fresh air equipment. Background Art

[0002] At present, the existing fresh air fans have a full heat exchange core with energy exchange function inside, which exchanges heat between the polluted air discharged from the outside and the fresh air sent into the room, thereby achieving the purpose of recovering cold and heat. The conventional full heat exchange core on the market cannot meet the requirements of both bottom installation and side installation. Bottom installation means that the full heat exchange core is installed in the box from the top installation port of the box along the up and down direction, while side installation means that the full heat exchange core is installed in the box from the side installation port of the box along the side direction. Since the existing core is generally provided with a handle belt, while ensuring the sealing between the core and the box in the bottom installation method, the sealing between the core and the box in the side installation method cannot be guaranteed; when installing from the bottom, the core needs to add a plate block on the upper and lower end surfaces to reinforce the core, which is costly, and a pull-out handle needs to be installed on the sheet metal on one side, and the process is cumbersome; when installing from the side, the core also needs to add a plate block on the upper and lower end surfaces, which is costly, but because it is a side installation method, the upper and lower end surfaces are sealing surfaces, and the pull-out handles cannot be installed, and the four side surfaces are air inlet and outlet surfaces, so the pull-out handles cannot be installed either. Therefore, the installation of the existing full heat exchange core is extremely inconvenient. Summary of the invention

[0003] The purpose of the present invention is to provide a full heat exchange core and a fresh air fan suitable for fresh air equipment to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] First, the present invention provides a full heat exchange core suitable for fresh air equipment, which includes: a core body in a three-dimensional rectangular shape, two reinforcement panels respectively arranged at the upper and lower ends of the core body, the reinforcement panel is in a rectangular plate shape, and at least one handle assembly is arranged on the outer edge of the reinforcement panel, and the handle assembly is arranged on the corners of the reinforcement panel.

[0006] When installing the full heat exchange core, the core can be pulled sideways or up and down by using the handle assemblies on the corners of the reinforcement panel, which can satisfy both bottom installation and side installation methods. The handle assemblies are arranged on the corners of the reinforcement panel, which does not affect the sealing of the two installation methods of the full heat exchange core. The reinforcement panel and the handle assembly are combined together to reduce the manufacturing cost.

[0007] As a further improvement of the above technical solution, the four corners of the reinforcement panel are provided with the handle assembly. This solution provides four handle assemblies, which can improve the flexibility of the installation of the full heat exchange core. During installation, people can pull any handle assembly at will, and the posture for the core installation is relatively arbitrary.

[0008] As a further improvement of the above technical solution, the corners of the reinforcement panel are arranged in a cut-angle structure, and the handle assembly includes two handle buckles, which are respectively arranged at the two ends of the corners of the reinforcement panel, and the handle buckles are in a right-angle folding plate structure, and the handle buckles include a first folding plate connected to the reinforcement panel, and a second folding plate connected to the first folding plate by bending, and the second folding plates on the upper and lower ends of the core body are bent toward each other.

[0009] The corners of the reinforcement panel in this solution are arranged in a cut-angle structure, which mainly provides a position for the handle buckle to be installed. The handle assembly in this solution includes two handle buckles, which are respectively arranged at the two ends of the corners of the reinforcement panel. People can pull the two handle buckles by hand, which makes it more convenient to pull. The handle buckle in this solution is a right-angle folding plate structure, and the second folding plates on the upper and lower ends of the core body are bent towards each other, so that the upper and lower end surfaces of the full heat exchange core are arranged flat, so as to facilitate the sealing installation of the full heat exchange core.

[0010] As a further improvement of the above technical solution, side sealing strips are arranged on the four edges of the outer side of the core body. Since the four sides of the core body are two air inlet surfaces and two air outlet surfaces, the side sealing strips on the four edges of the outer side of the core body can separate the four sides on the outer periphery to avoid air leakage, thereby ensuring the sealing performance when installing on the side and at the bottom.

[0011] As a further improvement of the above technical solution, the four outer sides of the core body are all provided with a cut-angle structure, and the four outer sides of the core body are all provided with a side mounting groove, the side sealing strip is installed in the side mounting groove, and the two handle buckles on each handle assembly are respectively on both sides of the side mounting groove.

[0012] The two handle buckles in this solution do not affect the sealing effect of the side sealing strip, and the side sealing strip is installed on the side installation groove, which can improve the firmness of the installation of the side sealing strip and avoid displacement.

[0013] As a further improvement of the above technical solution, two end surface sealing strips are arranged on the outer surface of the reinforcement panel, the two end surface sealing strips are arranged crosswise, and the two end surface sealing strips are respectively extended along two diagonal lines of the reinforcement panel.

[0014] In addition, the present solution also arranges end face sealing strips on the outer surfaces of the two reinforcement panels, and there are two end face sealing strips, which extend and cross along the two diagonal lines of the reinforcement panels respectively. The purpose of such arrangement is to separate the four sides of the reinforcement panel, that is, to separate the four wind surface sealing strips at the two ends, thereby further improving the sealing of the full heat exchange core installation.

[0015] As a further improvement of the above technical solution, two end surface installation grooves are provided on the upper surface of the reinforcement panel, and two end surface sealing strips are installed on the two end surface installation grooves in a one-to-one correspondence. The end surface installation grooves can improve the firmness of the installation of the end surface sealing strips.

[0016] As a further improvement of the above technical solution, the end of the side sealing strip is butted against the end of the end face sealing strip, and both the side sealing strip and the end face sealing strip are sponge strips.

[0017] In addition, the present invention provides a fresh air fan, which includes the above-mentioned full heat exchange core and also includes a body, the body is provided with a full heat exchange chamber, the full heat exchange chamber is provided with a side mounting port arranged on the side of the body, the full heat exchange core is laterally installed in the full heat exchange chamber from the side mounting port, and the side mounting port cover is provided with a side cover plate.

[0018] The full heat exchange core in this solution is installed from the side, that is, a side installation port that passes through the full heat exchange chamber is provided on the side of the body, and the full heat exchange core is installed laterally in the full heat exchange chamber from the side installation port, and then the side installation port is blocked by a side cover plate. During installation, one of the corners of the full heat exchange core faces the outside of the side installation port, so that the maintenance personnel only needs to pull the handle assembly on the corner.

[0019] The present invention also provides a fresh air fan, which includes the above-mentioned full heat exchange core and also includes a body, the body is provided with a full heat exchange chamber, the full heat exchange chamber is provided with a top surface mounting port arranged on the top surface of the body, the full heat exchange core is installed in the full heat exchange chamber from the top surface mounting port downward, and the top surface mounting port cover is provided with a top cover plate.
