Transportable active cooling container
A transportable enclosure can include a housing, a power source, a container, an evaporator, a condenser, a compressor, and a controller. The container can be configured to receive a temperature sensitive item therein. The evaporator can be disposed at least partially around the container. The condenser can be positioned near a wall of the housing and can be configured to reject heat from the evaporator to an ambient environment through the wall of the housing.
1. A transportable enclosure for actively controlling a temperature of a temperature-sensitive item, the transportable enclosure comprising:
a housing including a lid;
a container positionable within the housing and configured to receive and retain the temperature sensitive item therein;
an evaporator extending at least partially around the container;
a condenser located near a wall of the housing and configured to reject heat from the evaporator to an ambient environment through an opening in the wall of the housing;
a power supply enclosure supporting a power supply;
a power supply heat spreader connected to the power supply enclosure and a heat spreader to exchange heat between the power supply, the evaporator, and a heater;
a compressor to circulate a refrigerant between the evaporator and the condenser; and
a controller configured to operate the compressor to maintain a temperature setpoint within the container.
2. The Transportable enclosure of claim 1 , further comprising:
the heater connected to the container to heat the container.
3. The transportable enclosure of claim 2 , wherein the controller is configured to operate the heater to maintain the temperature setpoint within the container.
4. The transportable enclosure of claim 1 , further comprising:
the heat spreader at least partially surrounding the container.
5. The transportable enclosure of claim 4 , further comprising:
the heater connected to the heat spreader and configured to heat the heat spreader.
6. The transportable enclosure of claim 5 , wherein the heat spreader is shaped complementary to the container.
7. The transportable enclosure of claim 5 , wherein the evaporator surrounds at least a portion of the heat spreader and at least a portion of the evaporator is directly connected to the heat spreader.
8. The transportable enclosure of claim 5 , further comprising:
a filter drier connected to a liquid line downstream of the condenser, the filter drier oriented to be thirty degrees from vertical with respect to the housing.
9. A transportable enclosure for actively controlling a temperature of a temperature-sensitive item, the transportable enclosure comprising:
a housing including a lid, the housing including:
a plurality of intake bores and a plurality of exhaust bores extending through a wall of the housing; and
a spacer fin extending outward from the wall of the housing, the spacer fin positioned between the intake bores and the exhaust bores;
a container positionable within the housing and configured to receive and retain the temperature sensitive item therein;
an evaporator extending at least partially around the container;
a condenser located near a wall of the housing and configured to reject heat from the evaporator to an ambient environment through an opening in the wall of the housing;
a compressor to circulate refrigerant between the evaporator and the condenser;
a condenser fan located within the housing to deliver ambient air to the condenser;
a heater connected to the container to heat the container; and
a controller configured to operate the compressor and the heater to maintain a temperature setpoint within the container.
10. The transportable enclosure of claim 9 , further comprising:
a plurality of vacuum insulated panels positioned within the housing and at least partially around the container, the evaporator, and the heater.
11. The transportable enclosure of claim 9 , wherein the exhaust bores extend through the wall of the housing such that the exhaust bores are configured to discharge exhaust air from the housing in a direction away from the intake bores.
12. The transportable enclosure of claim 11 , wherein the intake bores extend through the wall of the housing such that the intake bores are configured to intake the ambient air into the housing in a direction away from the exhaust bores.
13. The transportable enclosure of claim 9 , wherein the housing includes a spacer fin extending outward from the wall of the housing, the spacer fin positioned laterally outward of the intake bores and including a plurality of bores extending therethrough to allow the exhaust air to pass through the spacer fin.
14. A transportable enclosure for actively controlling a temperature of a temperature-sensitive item, the transportable enclosure comprising:
a housing including a lid;
a rechargeable power source secured to the housing;
a container positionable within the housing and configured to receive and retain the temperature sensitive item therein;
an evaporator extending at least partially around the container;
a condenser located near a wall of the housing and configured to reject heat from the evaporator to an ambient environment through an opening in the wall of the housing;
a shock absorber positioned between the housing and the container, the shock absorber including:
a first shock absorber having a geometric shape of a first gyroid; and
a second shock absorber having a geometric shape of a second gyroid that is different from the first gyroid;
a compressor powered by the power source to circulate a refrigerant between the evaporator and the condenser; and
a controller powered by the power source and configured to operate the compressor to maintain a temperature setpoint within the container.
