Installation structure and ventilation system of heat exchange core

Abstract

The invention discloses an installing structure for a heat exchanger core. The installing structure comprises a first structural piece used for installing the heat exchange core and a second structural piece fixed relative to the heat exchanger core. The first structural piece comprises a T-shaped groove, and the second structural piece comprises a T-shaped piece. The T-shaped piece is arranged in the T-shaped groove in a sliding fit manner. In the installing structure for the heat exchanger core, at least one pair of matching faces closely attached can be formed between the T-shaped piece and the T-shaped groove so that airflow can be prevented from reaching the other side of the T-shaped piece from one side of the T-shaped piece, accordingly, a good sealing effect can be achieved, and mutual playing and mixing of fresh air and indoor exhaust air are prevented. The invention further discloses a ventilation system.

Description

technical field [0001] The invention relates to the technical field of air conditioning devices, in particular to a heat exchange core installation structure. The invention also relates to a ventilation system. Background technique [0002] In various ventilation systems (such as fresh air system or air conditioning system with fresh air function), the sealing installation of the heat exchange core and the installation of the filter cannot be ignored. In particular, if the heat exchange core is installed with insufficient sealing, it will cause the outdoor fresh air and the indoor exhaust air to cross each other, thereby affecting the ventilation effect. [0003] To solve this problem, the patent document CN201003839Y discloses an air conditioning device with a flexible sealing structure, the main structure of which is as follows: figure 1 shown. The four side edges of the rectangular parallelepiped plate heat exchanger 1 are fixed on the casing of the ventilation system ...

AI Technical Summary

Problems solved by technology

[0004] However, since the structure disclosed in this patent document relies on the compression of the sealing strip to achieve the effect of flexible sealing adjustment, in actual installation, due to problems such as installation errors and the deformation of the matching material due to gravity, the sealing strip cannot be guaranteed to be evenly compressed. force and are in the best compression state, it can not fit tightly, so can not guarantee a reliable sealing effect
