Embodiment 1

[0030] The heat exchange core structure disclosed in Embodiment 1 of the present invention is as follows image 3 As shown, it includes corrugated heat exchange channels arranged in the same direction with multiple layers of heat exchange channels. Assume that the heat exchange channels of odd-numbered layers are fresh air heat exchange channels 31, and the heat exchange channels of even-numbered layers are exhaust air heat exchange channels 32.

[0031] The heat exchange diagram is as Figure 4 As shown, the dotted arrow represents the direction of fresh air, and the solid arrow represents the direction of exhaust air. It can be seen that the fresh air enters through the fresh air heat exchange channel and flows along the channel. The exhaust air entering from the exhaust air heat exchange channel and the fresh air flow horizontally and countercurrently. The two fully conduct full countercurrent heat exchange during the flow process, which improves the heat exchange efficiency. ...

Embodiment 2

[0033] The heat exchange core structure disclosed in Embodiment 2 of the present invention is as follows Figure 5 As shown, it can be seen from the figure that the heat exchanger in this embodiment includes multiple layers of heat exchange channels placed in the same direction. The heat exchange channels of adjacent layers are staggered along the channel direction by a certain distance. The heat exchange channel is the fresh air heat exchange channel 51, and the heat exchange channel of the even-numbered layer is the exhaust air heat exchange channel 52. The exhaust air inlet channel 53 and the fresh air inlet channel 54 are respectively formed at both ends of the channel, so that the gas can be easily moved along. The intake channel enters the heat exchange channel, which speeds up the heat exchange efficiency of the heat exchanger.

[0034] In this embodiment, the distance that the heat exchange channels of adjacent layers are staggered along the channel direction can be set ac...

Embodiment 3

[0036] The heat exchange core structure disclosed in Embodiment 3 of the present invention is as follows Image 6 As shown, it includes a fresh air heat exchange passage 61, an exhaust air heat exchange passage 62, an exhaust air intake passage 63, a fresh air intake passage 64 and a sealing guide block 65. The sealing guide block 65 is connected to the edges of the adjacent heat exchange passages of each inlet passage, and seals the inlet passage into an inlet passage cavity, so that the gas can only enter the inlet passage cavity in a direction perpendicular to the passage. Then flow into the heat exchange channel.

[0037] The structure of the sealing guide block in this embodiment is as Figure 7 As shown, the outer side is a rectangular plane, and the inner side is a double-sided arc. When the gas enters along the cavity of the inlet channel, it enters the heat exchange channel uniformly and quickly under the guidance of the arc, so that the gas can exchange heat evenly and q...

Abstract

The invention discloses a heat exchanging core body, and odd-level and even-level heat exchange passages of the heat exchanging core body are distributed in the same direction. The invention discloses an air-to-air total heat exchanger with the heat exchanging core body at the same time. The heat exchanging core body ensures that the air exchanges heat in a heat exchanger passage in a horizontal refluent mode by distributing the odd-level and even-level heat exchange passages in the same direction, so that fresh air and exhausted air can countercurrent exchange heat fully and the heat exchanging rate of the exchanger is improved. Air inlet passages of the heat exchanging passages in each level are formed by staggering the directions of the odd-level and the even-level heat exchange passages from the preset position, a seal baffle of a double cambered surface shape is used for sealing the air inlet passages into air inlet passage cavities, so that the air can evenly flow into the heat exchanging passage, then even countercurrent exchange heat of the fresh air and the exhausted air is realized and the heat exchanging efficiency is further improved.

Description

Technical field [0001] The invention relates to the technical field of air conditioning equipment, and in particular to a heat exchange core and a total heat exchanger with the heat exchange core. Background technique [0002] The total heat exchanger is an energy-saving equipment used for energy recovery of air conditioning exhaust. The main components are the shell and the heat exchange core set in the shell. In order to prevent the air supply and exhaust from mixing together, the air flow paths of the air supply and exhaust in the heat exchange core are completely separated by the partition. [0003] The traditional full heat exchanger adopts a cross-type heat exchange method, and its heat exchange core structure is as follows figure 1 As shown, the odd-numbered heat exchange channels and the even-numbered heat exchange channels adopt the method of vertical arrangement of the channels. The fresh air and exhaust air that need heat recovery and exchange enter the vertical directi...
