Abstract
A thermally controlled cabinet such as a grow cabinet having an internal chamber for containing objects such as plants, with a temperature control system that accurately and precisely maintains the temperature inside of the chamber.
Claims20
A grow cabinet comprising:
- a housing;
- a grow chamber inside of the housing for containing a living object;
- a light source and/or nutrient supply for facilitating growth of the living object;
- and
- a thermoelectric temperature control system for controlling temperature inside the grow chamber, the thermoelectric temperature control system comprising:
- a work liquid circuit having a work heat exchanger in thermal communication with an environment inside of the grow chamber;
- an ambient liquid circuit having an ambient heat exchanger in thermal communication with an ambient environment outside of the grow chamber;
- and
- a thermoelectric heat exchanger assembly interposed between the work liquid circuit and the ambient liquid circuit, the thermoelectric heat exchanger assembly having:
- a work side having a work liquid flow passage fluidly connected to the work liquid circuit;
- an ambient side having an ambient liquid flow passage fluidly connected to the ambient liquid circuit;
- and
- a thermoelectric device interposed between the work liquid flow passage and the ambient liquid flow passage, the thermoelectric device having a first side in thermal communication with the work liquid flow passage, and having a second side that is in thermal communication with the ambient liquid flow passage;
- wherein the thermoelectric device is configured to transfer heat between the ambient liquid circuit and the work liquid circuit for achieving and/or maintaining a desired temperature of the grow chamber.

A temperature controlled cabinet such as a grow cabinet, comprising:
- a housing;
- a chamber inside of the housing for containing items;
- and
- a thermoelectric temperature control system for controlling temperature inside the chamber, the thermoelectric temperature control system comprising:
- a work liquid circuit having a work heat exchanger in thermal communication with an environment inside of the chamber;
- an ambient liquid circuit having an ambient heat exchanger in thermal communication with an ambient environment outside of the chamber;
- and
- a thermoelectric heat exchanger assembly interposed between the work liquid circuit and the ambient liquid circuit, the thermoelectric heat exchanger assembly having:
- a work side having a work waterblock that at least partially forms a work liquid flow passage that is fluidly connected to the work liquid circuit;
- an ambient side having an ambient waterblock that at least partially forms an ambient liquid flow passage that is fluidly connected to the ambient liquid circuit;
- and
- a thermoelectric device interposed between the work liquid flow passage and the ambient liquid flow passage, the thermoelectric device having a first side in thermal communication with the work liquid flow passage, and having a second side that is in thermal communication with the ambient liquid flow passage for transferring heat between the ambient liquid circuit and the work liquid circuit;
- wherein the ambient waterblock is made of a first material, and the work waterblock is made of a second material, the first material of the ambient waterblock having a greater thermal conductivity than the second material of the work waterblock, such that thermal transfer with an external environment on the ambient side is maximized, and thermal transfer with the external environment on the work side is minimized.
