The heat exchanger core is a key component of the full heat exchanger in the fresh air system, capable of simultaneously exchanging temperature and humidity. A search revealed prior art (Announcement No.: CN201820286520.7) describing a full heat exchanger core with high thermal conductivity. The document states, "The present invention utilizes a plastic fiber retaining frame at the edge of the core plate. A plug-in rod is hinged to the outer edge of the retaining frame via a block. During use, the core, secured by the retaining frame, is inserted into a stainless steel reinforcement frame via the plug-in rod, thereby securing the core within the reinforcement frame. When the core needs to be replaced, it can be directly removed and replaced. The stainless steel reinforcement frame can be reused, achieving cost savings and effectively protecting the core." However, the excitation force generated by the high-speed fluid flow in the prior art can easily cause vibration in the plate-type core or reinforcement frame. Utility Model Content

[0003] In order to overcome the defects of the prior art, a vibration-resistant heat exchanger core is provided to solve the problem in the prior art that the excitation force generated by the high-speed flow of fluid easily causes the plate core or the reinforcement frame to vibrate.

The corner buffer blocks are clamped with the corners of the aluminum foil sheet through the rubber surface layer.

[0006] Furthermore, the corrugated plate is located at the interval between two adjacent groups of aluminum foil plates, and an upper frame plate and a lower frame plate are distributed on the upper and lower end surfaces of the full heat exchanger core.

[0007] Furthermore, the upper surface of the upper frame plate and the lower surface of the lower frame plate are bonded with shock-isolating pads, and the frame risers are connected and fixed to the upper frame plate and the lower frame plate via fixing studs.

[0008] Furthermore, the inner side surfaces of the upper frame plate and the lower frame plate are bonded to the aluminum foil sheet of the full heat exchanger core through rubber cushioning plates.

[0009] Furthermore, a snap-in groove is provided on the side of the corner buffer block, and the snap-in groove is L-shaped and snap-fitted at the four groups of corners of the aluminum foil sheet.

[0010] Furthermore, the reinforcing protrusion is a rounded rectangular block made of stainless steel; and is inserted at the edge of the distance between the upper and lower sets of aluminum foil plates.

[0011] Furthermore, the frame vertical plates, reinforcement protrusions and corner buffer blocks constitute the plate anti-seismic structure of the full heat exchanger core.
