[0001] The utility model belongs to the technical field of heat exchange chip equipment, and in particular relates to a heat exchange chip and a heat exchange core structure. Background Art

[0002] A heat exchanger is an air purification device that can filter and exhaust indoor air, and filter and input outdoor air into the room to achieve indoor air replacement. During operation, the heat exchanger can exchange heat between the air to be exhausted in the casing and the air to be input through the heat exchange core, which can play a role in heat preservation in hot summer or cold winter. It can be seen that the heat exchange core is the core component of the heat exchanger, which will directly affect the performance of the heat exchanger.

[0003] Currently, the existing heat exchange core is usually composed of multiple chip body monomers stacked together, and adjacent chip bodies are mostly connected by diagonal bonding. However, with the long-term use of the heat exchange core, the wind speed in the existing air duct is too high and will affect the adhesion effect between adjacent chip bodies, resulting in loose connections between adjacent chip bodies and affecting the heat exchange effect.

The bending portion can facilitate the fixed connection between the inclined portion and the transverse rib, and the inclined portion, the bending portion and the transverse rib are an integrated structural design, which can ensure the service life of the bending rib.

[0012] In the above-mentioned heat exchange chip, each side of the chip body connected to the bending rib has two side strips that are staggered up and down, and one end of the inclined portion is inserted and fixed between the two side strips. The inclined portion can be fixed in the side strip through the side strip to ensure the stability of the air duct and the heat exchange efficiency.

[0013] In the above-mentioned heat exchange chip, the inclined guide structure includes guide slopes arranged on the outside of two side edges of each side of the chip body that are not connected to the bending ribs and the longitudinal ribs, and the guide slope is formed on one side of the outer edge of the side edge and is inclined toward the other side.
