The invention relates to soil heat exchanger for soft soil, like and or clay, comprising a first long leg (1, 2) and in parallel with that leg a second long leg (5), which legs contain flow ways for a heat transferring liquid. The soil heat exchanger is designed to be pushed down into the soil with the bottom end foremost. To enable this with a soil heat exchanger, which fulfils high demands on thermal efficiency and which must not get damaged during the pushing down into the sand or clay, the soild heat exchanger according to the invention is designed with the first leg containing at least one heat-insulated pipe (1, 2) in a cover (31, 34) and with the second leg containing numerous narrow flow ways (6) in at least one wide, thin plate (5) that extends along the cover (31, 34) and is attached to it. |
