Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1 to Figure 3, according to the intercooler of a kind of marine engine of the specific embodiment of the invention, comprise intercooler body 3, air guide sleeve 5 and heat pipe 11, wherein the inside of intercooler body 3 has heat exchange chamber.Air guide sleeve 5 is arranged on the sidewall of intercooler body 3, one end of air guide sleeve 5 is provided with fan 6, heat pipe 11 is arranged in the heat exchange chamber of intercooler body 3, and one end of heat pipe 11 is stretched in air guide sleeve 5 (see Fig. 2), fan 6 operates and blows, and cools the heat pipe 11 in air guide sleeve 5.
According to heat transfer theory, phase-change heat transfer has larger convective heat transfer coefficient, namely heat pipe is the heat-exchanger rig that this principle of application is made, usually the lower liquid substance of boiling point is placed with in heat pipe, inner vacuum state, the present embodiment application heat pipe principle and structural feature make the internal-combustion engine intercooler of heat pipe cooling, high temperature air inlet after supercharging of internal combustion engine flows into intercooler body 3, when flowing through heat pipe 11, opposite heat tube 11 is heated, ebullition, gasification after the liquid coolant that boiling point in heat pipe 11 is lower is heated, air inlet heat after supercharging is taken away, therefore intake temperature after supercharging also reduces, air inlet after supercharging enters in the suction tude of internal-combustion engine thereupon.Simultaneously, after the gasification of heat pipe 11 inner refrigerant, to be risen rapidly in the inside along heat pipe 11 cooled after entering air guide sleeve 5, cooling liquefaction, the refrigerant return of post liquefaction to heat pipe 11, the inlet air heating after being again pressurized, so move in circles, reach the effect reducing intake temperature.
As a kind of preferred embodiment, intercooler body 3 is rectangular case, and air guide sleeve 5 is square sleeve section, and this square sleeve sections is fixed on the upper side wall of rectangular case.Particularly, intercooler body 3 can be shaping like this, namely rectangular case is enclosed by the thermal baffle 4 of base 15, front end-plate 14, end plate 16, air inlet end cap 2, give vent to anger end cap 8 and upside and forms, in the present embodiment, thermal baffle 4 forms a part for the sidewall of square sleeve section, namely square sleeve section and thermal baffle 4 one-body molded.Heat pipe 11 stretches into the inner chamber of air guide sleeve 5 through thermal baffle 4, particularly, thermal baffle 4 is provided with some mounting holes, inserting heat pipe 11, adopting gapless assembly structure, guarantee to seal intact ne-leakage between the mounting hole of heat pipe 11 and thermal baffle 4 for installing.
In such scheme, air inlet end cap 2 is integrated with suction port 1, end cap 8 of giving vent to anger is integrated with air outlet 9, as a kind of preferred embodiment, the outwardly formation funnel shape of outer wall of air inlet end cap 2, suction port 1 is located at funnel shaped reducing place (see Fig. 3).Give vent to anger the outwardly formation spine 81 of outer wall of end cap 8, spine 81 extends to side, and air outlet 9 is located at the extended spot (see Fig. 7) of spine 81.
In addition, the outer wall of front end-plate 14 and end plate 16 is provided with rib.
In such scheme, one end of air guide sleeve 5 is fixed with support 7, support 7 is fixed with frequency control motor 13, and frequency control motor 13 drives fan 6 to rotate, and the other end of air guide sleeve 5 is air guide sleeve air outlet 10 (see Fig. 2).As a kind of preferred embodiment, one end of square sleeve section has circular necking segment 51, frequency control motor 13 is fixed on the opening of circular necking segment 51 by support 7, in the rotating shaft that fan 6 is arranged on frequency control motor 13 and fan 6 is in the inside of circular necking segment 51.
In the present embodiment, according to well-known structural feature, lower boiling cooling medium is placed with in heat pipe 11, in the present embodiment, cooling medium is the liquid that boiling point is lower, and is evacuated by heat pipe 11, like this, the cooling medium ebullition, gasification of heat pipe 11 inside, temperature will reduce further, be conducive to heat conduction and the circulating reflux of heat pipe 11.
The specific works situation of the intercooler of the marine engine of the present embodiment is as follows: after the high temperature air inlet after supercharging enters intercooler body 3 by the suction port 1 of air inlet end cap 2, opposite heat tube 11 heats, i.e. ebullition, gasification after the low boiling cooling medium of heat pipe 11 inside is heated, and take away amount of heat, the steam carrying amount of heat rises rapidly in heat pipe 11, after steam flows through thermal baffle 4, namely (inside of air guide sleeve 5 has gas-entered passageway 12 to enter the region that cools of air guide sleeve 5, see Fig. 2), liquefy rapidly after steam cooling, and the bottom of heat pipe 11 is back to along the inwall of heat pipe 11, high temperature inlet air heating after being again pressurized, circulation like this is continuous, repeat such process of absorb heat-gasify-cool-liquefy-absorbing heat again, reach the object that air inlet after supercharging is cooled.
In addition, owing to have employed frequency control motor 13, the rotating speed of fan 6 can adjust accordingly according to the operating mode operation demand of internal-combustion engine, with cold rear intake temperature demand under satisfied different operating mode, when internal combustion engine start warming-up, frequency control motor 13 can be controlled and be in halted state, fan 6 does not work, then the air inlet after supercharging directly enters cylinder, the particularly winter low temperature time without cooling, when ambient air temperature is lower, significantly can shorten warm-up period.And when intake temperature is too high, can control frequency control of motor speed fan 13 improves rotating speed, add the air output of big fan 6, make intake temperature remain on perfect condition.
To sum up, the intercooler of the marine engine of the present embodiment by arranging air guide sleeve 5 and heat pipe 11 on intercooler body 3, and adopt heat pipe principle and structural feature, make the cooling effectiveness of intercooler high, cooling rate is fast.Owing to adopting heat-pipe technology, this intercooler does not affect by seawater corrosion, and the tubing of low cost can be adopted to manufacture, and economic benefit significantly improves.And in cold after intake temperature can according to engine operating condition change carry out corresponding adjustment, in the internal combustion engine start idling stage, intercooler is not to inlet air heating after supercharging, warm-up times shortens, make internal-combustion engine can enter load operating condition fast, response is faster, can reduce the discharge amount of the long noxious emission caused of warm-up times simultaneously.Whole apparatus structure is compact, installs simple, highly versatile.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
