Description

The utility model relates to the field of heat exchangers, namely to radiators of the cooling system of internal combustion engines.

A radiator for a cooling system of an internal combustion engine is known from the prior art, comprising left and right manifolds with inlet and outlet pipes and bottoms, in which the ends of the tubes are fixed in two vertical rows, fixed horizontally and parallel to each other in the lamellas by means of the burning of the tube cavities (see patent RU 148170, class F28D 1/053, publ. 11/27/2014). The known radiator is equipped with integral parallel nozzles, made at the same time with the collectors, which greatly complicates its installation.

A technical problem is the creation of a radiator of universal design, which will make it easy to install it in any type of cooling system.

In the proposed radiator of the cooling system of an internal combustion engine, comprising left and right manifolds with inlet and outlet pipes and bottoms, in which the ends of the tubes are fixed in two vertical rows, fixed horizontally and parallel to each other in the lamellas by means of the tube cavities, the nozzles are arranged orthogonally to each other friend, and one of them is equipped with a removable L-shaped tap.

The combination of the above features allows you to solve the above technical problem and get a technical result, which consists in simplifying the installation of the radiator.

In FIG. 1 shows a proposed radiator, front view;

in FIG. 2 - same, right view;

in FIG. 3 - the same, top view;

in FIG. 4 - node A of FIG. one;

in FIG. 5 - bottom of the collector, inside view.

The radiator of the cooling system of an internal combustion engine consists of a left collector 1, a right collector 2 and a heat exchange part 3, which provides heat removal from the coolant by a passing air stream. Part 3 includes aluminum tubes 4 fixed horizontally and parallel to each other in aluminum plates - lamellas 5 - by burning the cavities of the tubes 4 (the design is designed so that after the burning process the outer dimension of the tubes 4 becomes larger than the holes in the lamellas 5, thereby making the tubes 4 tight crimped by the lamella 5). Tubes 4 are arranged in two rows of 9 pieces. in each, the rows are oriented vertically (corridor arrangement). The ends of the tubes 4 are fixed in the bottoms 6 of the collectors 1, 2 by means of flaring and are tightly crimped by sealing rubber gaskets 7.

To improve heat transfer in the cavities of the tubes 4 are plastic turbulators (not shown in the drawings). To protect against aggressive environments and active coolant additives, bottom 6 is made of sheet steel with a corrosion-resistant coating. Sealing gaskets 7 are made of ethylene propylene rubber (EPDM) and provide stable operation of the radiator even with a significant difference in coolant temperatures.

Collectors 1, 2 are made of heat-resistant glass-filled polyamide grade PA66-GF30 (this material can withstand high pressure and temperature drops of the coolant) and are equipped with inlet 8 and outlet 9 nozzles, which can be installed on different or one (as in the drawings) of collectors 1, 2. Pipes 8, 9 are arranged orthogonally to each other, and one of them is equipped with a removable L-shaped branch 10. Branch 10 is preferably installed through a rubber gasket (not shown in the drawings). This design makes it easy to adapt the radiator to any configuration of the cooling system and greatly simplifies its installation in the car heater box.

The proposed radiator is collected as follows.

The tubes 4 are installed in the design position in the lamellas 5 and are fixed by means of a mandrel. After that, the bottom 6 is installed on the ends of the tubes 4 and fixed by flaring the ends of the tubes 4. On the bottom 6, the outer part of the collectors 1, 2 is installed and crimped along the perimeter with the teeth of the bottoms 6. In this case, the ribs of the outer parts of the collectors 1, 2 are tightly pressed against the rubber gasket 7, which provides reliable tightness of the product. The nozzles 8, 9 are integral with the collector / collectors 1, 2, and the outlet 10 is fixed with bolts 11.

Using the proposed device by simplifying the installation of the radiator can significantly reduce the installation time and allows you to adapt to any cooling system.
