Abstract

A heat exchanging module comprises a casing, a plurality of first air guiding elements and a plurality of first separation elements. The first air guiding elements are disposed in the casing. Each of the first air guiding elements comprises a plurality of first structures and a plurality of second structures, the first structures are disposed parallelly, and the second structures are disposed between the first structures and connected with the first structures to form a plurality of first channels. Each of the first separation elements is disposed between the two adjacent first air guiding elements to form a second channel. An airflow direction of the first channels is different from that of the second channels. The present invention further provides an electronic device using the same.

First claim

What is claimed is:

1. A heat exchanging module, comprising:
a casing;
a plurality of first air guiding elements disposed in the casing, wherein each of the first air guiding elements comprises a plurality of first structures and a plurality of second structures, the first structures are disposed parallelly, and the second structures are disposed between the first structures and connected with the first structures to form a plurality of first channels;
a plurality of first separation elements, wherein each of the first separation elements is disposed between the two adjacent first air guiding elements; and
a plurality of second separation elements, wherein each of the second separation elements are disposed between the adjacent two first air guiding elements, and the first separation elements and the second separation elements are respectively disposed along two opposite edges of the corresponding two first air guiding elements to form a plurality of second channels, and an airflow direction of the first channels is different from that of the second channels,
wherein the airflow direction of the first channels is toward a constant direction, and the airflow direction of the first channels and the airflow direction of the second channels form an included angle of 90° in a projection direction.

2. The heat exchanging module as recited in claim 1 , wherein the first channels have identical airflow direction, and the second channels have identical airflow direction.

3. The heat exchanging module as recited in claim 1 , wherein the first channels and the second channels are inward circulating channels and outward circulating channels respectively or outward circulating channels and inward circulating channels respectively, and
the inward circulating channels and the outward circulating channels are disposed alternately and separately.

4. An electronic device, comprising:
an electronic device body, wherein a heat exchanging module is disposed to the electronic device body and comprises:
a casing;
a plurality of first air guiding elements disposed in the casing, wherein each of the first air guiding elements comprises a plurality of first structures and a plurality of second structures, the first structures are disposed parallelly, and the second structures are disposed between the first structures and connected with the first structures to form a plurality of first channels;
a plurality of first separation elements, wherein each of the first separation elements is disposed between the two adjacent first air guiding elements; and
a plurality of second separation elements, wherein each of the second separation elements are disposed between the adjacent two first air guiding elements, and the first separation elements and the second separation elements are respectively disposed along two opposite edges of the corresponding two first air guiding elements to form a plurality of second channels, and an airflow direction of the first channels is different from that of the second channels,
wherein the airflow direction of the first channels is toward a constant direction, and the airflow direction of the first channels and the airflow direction of the second channels form an included angle of 90° in a projection direction.

5. The electronic device as recited in claim 4 , wherein the first channels have identical airflow direction, and the second channels have identical airflow direction.

6. The electronic device as recited in claim 4 , wherein the first channels and the second channels are inward circulating channels and outward circulating channels respectively or outward circulating channels and inward circulating channels respectively, and
the inward circulating channels and the outward circulating channels are disposed alternately and separately.
