Abstract
An indirect evaporative cooling apparatus includes a housing, a heat exchanger core, a bypass valve, a filter, an indoor fan, and an outdoor fan. The heat exchanger core is in the housing. A first space, a second space, a third space, and a fourth space are formed by the heat exchanger core and the housing, and a first air vent, a second air vent, a third air vent, and a fourth air vent are disposed in the housing. The first space and the second space are connected by using the heat exchanger core to constitute an indoor circulation air duct, the third space and the fourth space are connected by using the heat exchanger core to constitute an outdoor circulation air duct.
Claims20
An indirect evaporative cooling apparatus, comprising:
- a housing;
- a heat exchanger core disposed in the housing, wherein the heat exchanger core and the housing form a first space, a second space, a third space, and a fourth space, wherein the first space and the second space are connected by using the heat exchanger core to constitute an indoor circulation air duct, and wherein the third space and the fourth space are connected by using the heat exchanger core to constitute an outdoor circulation air duct;
- a first air vent disposed in the housing and connecting the first space and the outside of the housing;
- a second air vent disposed in the housing and connecting the second space and the outside of the housing;
- a third air vent disposed in the housing and connecting the third space and the outside of the housing;
- a fourth air vent disposed in the housing and connecting the fourth space and the outside of the housing;
- an indoor fan disposed in the indoor circulation air duct and configured to direct air from the first space towards the second space;
- an outdoor fan disposed in the outdoor circulation air duct and configured to direct air from the third space towards the fourth space;
- a filter disposed at the third air vent;
- and
- a bypass valve disposed between the first space and the third space and configured to allow air to pass from the indoor circulation air duct, through the bypass valve, to the third space, towards the filter and through the third air vent.
A cooling system, comprising:
- an indirect evaporative cooling apparatus comprising:
- a housing;
