Claims

The invention relates to mechanical engineering, in particular to designs of water heaters with a water jacket surrounding the combustion chamber, intended for pre-launch preparation of internal combustion engines of transport vehicles under conditions of low ambient temperatures. Known devices for preheating the cooling of the internal combustion engine include a boiler located in a thermally insulated housing and connected to the engine cooling system, furnace and pump placed on the wall of the boiler and connected to a sub collector with distributor valves Dl However, known installations are not sufficiently efficient. for heat losses in the communications connected to the pump installed outside, and due to the loss of heat carrier, it is not possible to drain the last of the two and gattel to the boiler, as well as the impossibility of draining the coolant from the pump and manifolds after the engine has been heated. The purpose of the invention is to increase the heating efficiency. The goal is achieved by the fact that the firebox is equipped with an additional casing adjacent to it, and the pump and supply manifold are placed inside a thermally insulated housing. FIG. 1 shows a device for heating a coolant, a longitudinal section; in fig. 2 shows section A-A in FIG. 1. A device for preheating the coolant of an internal combustion engine contains a boiler 1 placed in a thermally insulated housing 2 installed on a skid x 3 and connected by means of connecting: sleeves 4 to the engine cooling system, with 1 heating 5 equipped with an additional adjoining liquid casing 6, and the pump 7, placed on the wall 8 of the boiler 1, connected to the supply manifold 9 with dispensing valves 10. The device works as follows. Before starting the engine cooling system of the trans-machines with the help of connecting sleeves 4, they are connected to the installation, the dispensing valves 10 are turned off, the pump 7 is turned on and the heat carrier preheated in the boiler I using the furnace 5 is circulated through the boiler-engines system .... At the end of the engine warm-up, the drain valves and dispensing valves 10 are closed, and the pyjKaBa 4 are disconnected from the engine. Upon completion of the transport vehicles, their engines are connected to the installation, the drain valves of the engines are opened and the liquid is drained by gravity into the boiler 1.
