Embodiment
Refer to shown in Fig. 1, Fig. 2, a kind of marine tidal-current energy generator group cooling device of the present invention, comprises shell 3 and inner casing 4, and shell 3 and inner casing 4 surround annular heat exchanging chamber, and the rear and front end of described annular heat exchanging chamber is sealed respectively by front end-plate 1 and end plate 2; Described inner casing 4 is provided with the cooling liquid inlet 6 and cooling liquid outlet 7 that are communicated with annular heat exchanging chamber, described cooling liquid inlet 6 is separated by the demarcation strip 9 be arranged in annular heat exchanging chamber with cooling liquid outlet 7, and described shell 3 is the cabin shell of described marine tidal-current energy generator group.
Preferably, described shell 3 is one section of cabin shell on the housing of cabin, and the shell section of engine room inside main equipment weight and performance load is not preferably born in its position.Thus, shown in Fig. 3, cabin housing is divided to be gone out to be positioned at the cabin leading portion 12 before described front end-plate 1 and is positioned at described end plate 2 cabin back segment 13 below.Front end-plate 1 is connected with cabin leading portion 12, and end plate 2 is connected with cabin back segment 13.
The operation principle of cooling device of the present invention is, absorb the high temperature coolant after main heat-producing device heat and enter annular heat exchanging chamber inside from cooling liquid inlet 6, cooling fluid flows in annular heat exchanging chamber, pass through cabin shell by heat and external sea water coke slurry simultaneously, cooling fluid after cooling flows out from cooling liquid outlet 7, get back to main heat-producing device, form loop.Namely cooling device of the present invention combines as a joint in cabin with part cabin shell, and this joint cabin shell carries out heat exchange as thermal component and seawater, thus realizes cooling the medium in annular heat exchanging chamber.
Shown in Fig. 2, for preventing heat from conducting to engine room inside, be provided with thermal insulation layer 5 inside inner casing 4, thermal insulation layer 5 can directly be bonded on inner casing 4.Thermal insulation layer 5 also can be arranged on as required outside inner casing or in interior outside and arrange simultaneously.Further, in order to more fully heat insulation, thermal insulation layer 5 can extend covering front end-plate 1 and end plate 2 further.
