A weatherproof cabinet with multiple-compartment cooling includes a housing and a door attached to the housing. The door includes a heat exchanger core, a first duct located at least partially between the heat exchanger door and an exterior of the door, and a second duct located at least partially between the heat exchanger door and an electronics compartment. The door also includes an inlet vent and an outlet vent that are pneumatically interconnected with the first duct. A fan is located at least partially within the first duct and is operative to draw external air into the first duct via the inlet vent, direct at least the first portion of the external air across the heat exchanger core, and then direct the first portion of the external air out of the first duct via the outlet vent. A partition is located within the first duct and separates the inlet vent from the outlet vent so that external air is not drawn into the first duct via the outlet vent during operation of the fan.

A cooling device includes: a partition plate for partitioning an interior of a case into a first fluid passage through which first fluid having a high temperature flows and a second fluid passage through which second fluid having a low temperature flows; a heat receiving portion disposed in the first fluid passage; a heat radiating portion disposed in the second fluid passage; and a connection pipe for communicating the heat receiving portion and the heat radiating portion. The heat radiating portion is disposed at an upper side of the heat receiving portion in such a manner that the second fluid from a front side of the heat radiating portion flows into a rear side of the heat radiating portion through a pipe space between the heat radiating portion and the heat receiving portion, and further passes through the heat radiating portion from the rear side toward the front side of the heat radiating portion. Thus, the cooling device has a small size while improving the cooling capacity of the cooling device.

A method and system are disclosed for cooling a heat generating object. A coolant is passed through a heat exchanger so that heated air passing through the heat exchanger is cooled. A fan unit is selectively positioned adjacent to a first side of the heat exchanger. When activated, the fan unit draws the cooled air through the heat exchanger and directs the cooled air towards the heat generating object. The fan unit may be repositioned along a second side of the heat exchanger so as to redefine the flow of air drawn from and directed towards the heat generating object.

This invention provides a closed-loop cycling type heat-dissipation apparatus, including at least one metal conduit and plural heat-dissipation fins. Hot air in a housing of a screen module is channeled into the metal conduit through an upper exit of the housing. Heat-dissipation fins attached onto the metal conduit then make heat exchange with atmosphere. The heat of the hot air is dissipated to atmosphere by thermal convection or thermal radiation of surfaces of the heat-dissipation fins. The hot air is cooled down and then channeled into the housing of the screen module through a lower entrance thereof. A closed-loop heat-dissipation cycle is formed. Inner temperature of the housing and temperature difference between inner part and outer part of the housing are effectively lowered. The present apparatus can provide a capability sufficient for heat-dissipation while without the aid of other baggage. The heat-dissipation is relied on nature heat-dissipation cycle in a system and without thermal convection between air in the system and atmosphere.

A remote and portable, passively cooled and heated building that has a power system and telecommunications and other electrical equipment.

An outdoor equipment cabinet includes a housing with a first door for accessing an equipment compartment within the housing. A battery compartment is located proximate a bottom of the housing. First and second air vents are located in an upper half of the cabinet. At least one fan moves air from the first vent, down to the battery compartment and then up and out of the second vent. In some embodiments, the first door includes the second vent, and a dual wall construction leading to a heat exchanger mounted to the first door. Air passes through the dual wall construction of the first door and through the heat exchanger to regulate an air temperature within the equipment compartment, and then passes out the second vent. The first vent may be provided in a second door which also includes a dual wall construction to guide incoming air to the battery compartment.
