An interesting find! We are developers and equipment manufacturers. Smarheat is one of our many partners and distributors for our products. In 2016, they received from us, as from manufacturers, the right to distribute our products for one year, until 2017, but then we stopped working with them. In the picture that you sent above this is the first version of the server, also we have 2nd and 3rd version. Also in partnership with smartheat, they made for us only case for the 3rd version of heater (2016), but we did all the R&D for first one (2013) and the second (2014).
In the branch with the history of Hotmine (https://bitcointalk.org/index.php?topic=5114987.msg49947111#msg49947111) there will be two more versions, have patience
