(54) HEATER FOR VEHICLE

- „I

This invention relates to fc devices for heating cabins and salons of tpaHcnoptHbix products.

A heater is known for a vehicle cabin in which the heating of air entering the cabin is carried out with the help of a chamber where the toppive mixture T is burned.

Such a heater has a complicated co-structure due to the re-passage of the bridge to regulate the process of combustion of the fuel mixture.

The closest technical solution to the invention is a heater for a vehicle containing coaxially arranged pipes for circulating primary and secondary coolants, connected respectively to the heat source and the vehicle body, heat pipes installed perpendicular to the pipes and having evaporating and condensation parts, located in the specified pipe 2.

However, this heater does not have high operational performance due to the possibility of burning through heat pipes placed directly in the exhaust pipelines.

systems and having KOHtaKt with aggressive exhaust gases. In addition, the known design is inconvenient in maintenance and repair ...

The purpose of the invention is to increase the operational reliability of the heater.

This is achieved by the fact that the heater is equipped with a chamber having openings for heat pipes, installed between said pipes, and communicating with the atmosphere, and sleeves that are opened in the circulation pipe of the main heat carrier, while the evaporation parts of the heat pipes are installed in said sleeves.

FIG. I depicts the proposed heater, a longitudinal section; in fig. 2 is the same cross section.

The heater consists of a pipe 1 for circulating a hot-water heating medium, in the cavity of a pipe there are ribbed ends of heat pipes 2 passing through the chamber 3 into a pipe 4 for circulating the main heat carrier. Chamber 3 via openings 5 communicates with the atmosphere. In the wall of the pipe 4, which separates it from the chamber 3, the sleeves 6 are rigidly fixed, which can be ribbed. The pipe 4 is a section of the exhaust path 7. When heated exhaust gas is supplied to the pipe 4, the lower ends of the heat pipes 2 are heated. 1 through pipes 2, heat energy is used to heat the additional coolant — air in the vehicle cabin. In the case of burnout of the liner or the wall of the nozzle 4, the exhaust gases do not penetrate into the cabin, and through the openings of the chamber 3 they escape to the atmosphere. To replace the heat pipes, it is enough to remove the pipe 1, and the exhaust gas path with the chamber 4 remains in the assembled state. The use of exhaust gas heat significantly increases the engine's efficiency and service life, especially under the conditions of the Far North and, moreover, the cabin is heated much faster due to an increase in exhaust gas temperature immediately after the engine start.
