Problems solved by technology

If the spacing between the supporting ribs is too small, the supporting ribs will occupy too many airflow channels, increase the resistance, and reduce the heat exchange efficiency; if the spacing between the supporting ribs is too large, the support for the heat conduction fins will become weaker. Due to the negative pressure formed inside the heat exchanger during use, the heat conduction fins will be significantly deformed, which will also affect the resistance and heat exchange efficiency

Embodiment Construction

[0054] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements. In addition, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a comprehensive understanding of the embodiments of the present disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in diagrammatic form to simplify the drawings.

[0055]The applicant found that when the corrugated support plate is used in a hexagonal prism total heat exchanger, since the wall thickness of the corrugated support plate can be very thin, there can be more support ribs under the same size condition , can effectively support the heat conduction sheet, and reduce the deformation of...

Abstract

The invention provides a total heat exchanger (100) with a corrugated structure. The total heat exchanger comprises an outer wrapping frame; and a heat exchange core (12), the total heat exchanger (100) being substantially prism-shaped; the outer wrapping frame comprises angle beads (11); the heat exchange core body (12) comprises a plurality of heat conduction pieces (15) made of total heat exchange materials and a plurality of corrugated supporting plates (16), the heat conduction pieces (15) and the corrugated supporting plates (16) are stacked in the heat exchange core body (12) in a staggered mode, so that each corrugated supporting plate (16) and the adjacent heat conduction pieces (15) form a branch airflow channel set (17), and each branch airflow channel set (17) comprises a plurality of branch airflow channels. The angle beads (11) are parallel to the overlapped extension direction; orthogonal projections of the plurality of heat conduction sheets (15) and / or the plurality of corrugated support plates (16) in a cross section perpendicular to the angle bead (11) are polygonal, and the number of edges is larger than or equal to six. The total heat exchanger with the corrugated structure is small in airflow resistance and high in heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of total heat exchangers, in particular to a method and device for reducing air duct resistance and improving heat exchange efficiency in a total heat exchanger with a corrugated structure inside a fresh air system. Full heat exchanger with corrugated structure. Background technique [0002] For most heat exchanger manufacturers, in the hexagonal full heat exchanger, the structural support frame basically adopts injection molding frame; due to the limitation of injection molding conditions, the thickness of the support rib cannot be made thin. If the spacing between the supporting ribs is too small, the supporting ribs will occupy too many airflow channels, increase the resistance, and reduce the heat exchange efficiency; if the spacing between the supporting ribs is too large, the support for the heat conduction fins will become weaker. Due to the negative pressure formed inside the heat exchanger during u...
