Description

The solution relates to cooling machines, in particular, to air cooling, and in particular, to devices for cooling charge air.

In an internal combustion engine, only a third of the fuel energy is converted into useful work. The effectiveness of this conversion largely depends on equipping the engine with a boost system and, in particular, on the charge air temperature. To date, the theoretical foundations for the design of radiators have been developed (see, for example, R. Bussien Automobile reference book, vol. 2, Mashgiz, M., 1959, pp. 156-163), which can be used in the calculation of devices for cooling charge-air air, while it is rational to use the known types and designs of radiators (see 163-166). Tubular radiators are widely known, containing reservoirs with caps interfaced with the manifolds, into which finned tubes are inserted, pressed to them through elastic gaskets with cuffs (see V.V. Burkov, Aluminum Radiators of Automotive Engines, Moscow-Leningrad, Mechanical Engineering, 1964, p. 55.56). The sealing of the ends of the tubes is made by pressing, and the lids of the tanks are fastened with clamping bars. A known cooling system of a turbo-piston engine of a vehicle, consisting of a fan, a pressurization unit with an air cooler, a water radiator (see the book Internal combustion engines under the general editorship of A.S. Orlin, M.G. Kruglova - M., Engineering, 1985 , p. 456). Due to irrevocable heat loss to the atmosphere, engine efficiency is low.

In a sectional radiator for a car according to SU 18088, sections of vertical tubes are used, arranged at least in two rows in the direction of the longitudinal axis of the car, and in a sectional radiator according to SU 8861 the sections are removable. In the radiator of the engine cooling system according to SU 357841, containing the upper and lower tanks and a core located between them, consisting of tubes and corrugated ribbons in height and depth, the ribbons are placed obliquely relative to the horizontal plane.

To increase the efficiency of operation and reduce the consumption of non-ferrous metal in the radiator section for heat exchange between liquid and gas according to SU 276634, fins are made in the form of wire meshes, for example, with a diameter of 0.1 mm s

bent ends attached to the tubes, for example, sintering. In order to intensify heat transfer in a sectional radiator according to SU 1245853, the large sides of each section in the finning zone are led outside the section on both its sides.

A known internal combustion engine according to US 1958156, equipped with a traditional liquid cooling system containing numerous nozzles. The engine cooling system according to US 1980811 is even more complex, and the system according to US 2498001 is multi-sectional.

The radiator according to FR 1225180 has a developed set of corrugations, the cooler according to FR 1211660 has tubes, and the converter according to FR 1238450 has tubes and corrugations. Particular attention in the automobile radiator according to FR 1291617 is given to the design of the tanks, in the radiator according to FR 1309629 - to the placement and execution of the corrugation, and in the section of the tubular-plate radiator according to SU 1636572 - to the transverse linear dimensions of the tubes. In the radiator according to RU 2162155 the channels for cooling air in the core are made of porous metal. In the radiator of a liquid cooling system of an internal combustion engine according to RU 38843, the tanks are made of variable cross-section, while the pipes are placed in places of larger cross-section. To increase the specific heat flux in the radiator according to SU 616518, the ends of the pipes in the compensation zone are combined by a common chamber, and the condensation and evaporation zones are separated by a partition.

The cooling efficiency in the deflectors according to DE 1476402 and UK 1326328 and 1334816 largely depends on the location of the fan. In addition, it was proposed to reduce cooling costs in the system according to SU 1495461 by making cooling plates and placing them. A great influence can be exerted on the efficiency of the radiators, both the dimensions of their main elements, as is the case in radiators according to SU 1604635 and 1813891, and their ratio (see, for example, systems according to SU 714030 and 727866).

To reduce vibration loads in the radiator mounting support according to SU 1009821, its support is made as a curved plate with different shelves, stiffeners and an oval hole. Through mounting holes are provided in the device for supporting the radiator according to JP 6041249. The cooling module according to DE 19731999 is supported on two pillars mounted on a vehicle. The radiator assembly of the ICE cooling system according to RU 21624 is equipped with damping gaskets, and each base plate has a second fastening means.

Despite the numerous designs of radiators, their components and parts, the use of the mentioned technical solutions will not allow to obtain an effectively functioning design of the charge air cooler of an internal combustion engine.

In engines according to US 2195082, 2235588, 2306277, 2518062, cooling of the charge air by a finned radiator is provided.

Coolers are provided in the power systems of turbo-charged internal combustion engines (see, for example, US 2355759, 2896598, 2388350, 2540916, 2474203, 2477668, 2500234, 2464548, 2491372, 2433326, 2518660, 2544973, 2474018, 2487049, 2627370, 2627370, 2727707 2952958, 3102381, 3103780, 3141293, 3096615, 3173242, 3143849, 3232042, 3303348 and 3355877; DE 859237, 953129, 1003505, 1113116, 1124765, 1220199, 1212778). In none of the above cases there is a description of the design of the cooler, which is important, despite the fact that the cases considered are those in which the regulatory body responds to several parameters of the working medium or engine operation, in particular, the parameter of the gaseous working medium of the engine. It should be noted that when describing the turbocharging method according to US 3336911, an indicator diagram of the engine is shown and the influence of the cooler is disclosed, as well as in the system according to US 3257797.

Gas turbine coolers according to US 2354698 and installations according to DE 834466 are complex in design and manufacture.

The device for cooling charge air according to SU 297787 contains a heat exchanger made in the fan housing with a developed cooling surface. The device for cooling a diesel engine according to SU 498915 contains heat exchangers, while the accuracy of regulating the temperature of the charge air is ensured by the installation of a thermostat and a throttle. The performance of both the cooling system according to SU 714030 and the cooling device according to SU 798335 depends on the choice of parameters of the fan, mixing chamber and channels. The cooling system of a supercharged internal combustion engine according to SU 1333796 is equipped with an additional fan, an air supply control unit is provided in the internal combustion engine according to SU 1483069 and in a diesel engine according to SU 1815360, and an additional heat exchanger is installed in the internal combustion engine according to SU 1539353. The cooler sections are united by a common prefabricated manifold and have separate distributing manifolds for a V-shaped turbocharged engine according to RU 2083855.

Such systems are complex and expensive to manufacture. The cooling system according to FR 2260690 is somewhat simpler, but control of the charge air temperature is difficult. Improved system performance

In systems according to US 2045816, 2362493, 2417363, 2508311, 2773348, 2983265, 3091228, coolers are made with a developed cooling area. Tubular coolers are made in devices according to US 2375006, 2579643, 24523008; DE 953201. Cross-movement of the cooling and working media is provided in devices according to US 2491380, 2544852, 2562890, 2702482, 2918787, 3142957.

A known cylindrical cooler coaxially mounted to a turbocharger, and equipped with spirally placed plates (see, for example, US 3257069). This design of the cooler is difficult, and placement is most often impossible. Rationally placed cooler in the engine according to US 3027706, while it is a tubular design with plates.

The cooler body has a flange mount to the engine crankcase. The cooler tanks are made in a molded case with multiple bolting to the core and are connected to the cooling system, while one of the frames has a separate mount to the adapter. Such a constructive implementation is difficult, while high costs are inevitable when operating the cooler. In essence, the use of a cooler as applied to another engine, as well as a change in the relative position of the cooler and engine, is excluded. It should be noted that a liquid medium was used in these coolers, which is not always rational.

Although the mentioned designs of coolers, their units and parts are not so diverse, their use will not allow to obtain an efficiently functioning design of the charge air cooler of an internal combustion engine.
