What is a borehole heat exchanger?

Borehole Heat Exchangers (BHE) are being increasingly utilized for heat purposes in public as well as communal infrastructure at depths ranging from 100 to 400 m. BHE technology allows for heat exchange between an underground rock mass and heat carrier, circulating in the closed-loop system between the surface and the reservoir.

Do you offer heat exchangers for heavy-duty mining equipment?

In fact, many of our heat exchangers come standard on some of the most relied-upon heavy-duty mining equipment in use today. We provide custom-built heat exchangers, radiators, and coolers for heavy-duty equipment manufacturers such as: Mesabi® heat exchangers are spec’d with a wide range of equipment used in mining operations today.

What is a downhole heat exchanger?

Furled tube in the foreground on the left. A downhole heat exchanger, (DHE) also called a borehole heat exchanger, (BHE) is a heat exchanger installed inside a vertical or inclined borehole. It is used to capture or dissipate heat to or from the ground. DHT's are used for geothermal heating, sometimes with the help of a geothermal heat pump.

How do heat exchangers work?

In northern Europe, DHE are already widely deployed. The heat exchanger usually consists of one or two u-tubes through which the carrier fluid, usually water, circulates. The space around the u-tubes is filled with groundwater or backfilled with thermally conductive grout. Another design uses a single open pipe to flow water downward.

What is a downhole heat exchanger (DHT)?

DHT's are used for geothermal heating, sometimes with the help of a geothermal heat pump. Downhole heat exchangers, like other use of geothermal energy, have the potential to significantly contribute to the reduction of CO 2 emissions. In northern Europe, DHE are already widely deployed.
