The specific embodiment
As depicted in figs. 1 and 2, liquid cooling machine, main by housing 1, form at the bobbin carriage 2 of housing 1 both sides, the tube sheet 3 between bobbin carriage and housing and the heat exchanger tube 4 being placed in housing.Saddle is set below housing, for liquid cooling machine being fixed on to ground or other equipment.It is cylindrical that housing is generally.
At the housing outer wall near housing one end margin, shell-side fluid import 11 is set, at the housing outer wall near housing other end edge, shell-side fluid outlet 12 is set, cooling fluid enters in housing from shell-side fluid import, and the shell-side fluid of flowing through from heat exchanger tube gap outlet is flowed out.
The bobbin carriage that is positioned at shell-side fluid import one end is provided with tube side fluid import 21, and another bobbin carriage is provided with tube side fluid outlet 22; Described heat exchanger tube is strip pipe, its two ends are separately fixed on tube sheet, the both ends open of heat exchanger tube lays respectively in bobbin carriage, and as shown in Figure 3, in described housing, from shell-side fluid import to shell-side fluid, the direction interval of outlet arranges many group cambered plates 5 and circular slab 6; As shown in Figure 4, cambered plate center is provided with centre bore for coolant flow, as shown in Figure 5, is provided with a circle discharge orifice for coolant flow along circular slab edge.
Need cooling liquid enter bobbin carriage from tube side fluid import 21, then flow into and be fixed on the heat exchanger tube 4 on tube sheet, flow through and be positioned at after the heat exchanger tube supervisor of housing, flow into the bobbin carriage that is positioned at housing opposite side, then from tube side fluid outlet 22 out.Cooling fluid flows in housings from shell-side fluid import 11, flows to the circular slab of next stage from cambered plate centre bore, then the discharge orifice through circular slab edge flows to the cambered plate of next stage, until flow out from shell-side fluid outlet 12.Cooling fluid in mobile process, flows through from the gap of heat exchanger tube in housing, takes away the heat on heat exchanger tube surface.Due to cambered plate and the setting of circular slab gap, force cooling fluid from the centre bore of cambered plate flows through changed course from the marginal flow mistake of circular slab, thereby it is cooling fully that heat exchanger tube is obtained, avoid cooling fluid from housing one end the linear other end that flows to, for the phenomenon of the concentrated cooling deficiency in center of heat exchanger tube.
What housing two ends and tube sheet were adjacent is cambered plate, force cooling fluid to flow to centre bore or to force cooling fluid to flow to shell-side fluid outlet from centre bore from shell-side fluid import, extend the flow process of cooling fluid, thereby can better take away the heat on heat exchanger tube surface.
Described shell-side fluid import 11 is on the housing wall between tube sheet and first cambered plate; Described shell-side fluid outlet 12 is on the housing wall between tube sheet and first cambered plate.
Described cooling fluid is water or oil.
Described Selection of Tubes in Heat Exchangers metal tube, is provided with fin or projection at heat exchanger tube outer wall, to expand the contact area with cooling fluid, so that heat radiation better.Its cross section be shaped as circle or ellipse, be preferably ellipse, the area that heat exchanger tube surface is contacted with cooling fluid is larger, and the inside needs the thickness of the liquid that dispels the heat moderate, thereby heat is easily absorbed by heat exchanger tube the liquid that is cooled, takes away.
Described cambered plate and circular slab are welded on inner walls.
Described tube sheet, cambered plate and circular slab are parallel to each other.
Centre bore area on a cambered plate equals the area sum of small-sized discharge orifice all on a circular slab, contributes to force cooling fluid to flow through more equably various piece in housing.
The centre bore of described heat exchanger tube on cambered plate around disperses to arrange.
Between any two heat exchanger tubes, all leave space, be convenient to cooling fluid from flowing through the heat of taking away heat exchanger tube surface between pipe, help liquid cools in heat exchanger tube.
Above-described embodiment is only for interpretation purposes of the present utility model; and be not to restriction of the present utility model, those skilled in the art, in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
