The pillow cells are filled with a liquid coolant, providing greater heat capacity due to the operating temperature range from minus 65 ° C to plus 120 ° C. The cover along with the pillow is sewn with thread around the perimeter and is additionally glued along the seam. A useful model can be used in the manufacture of auto blankets for warming the engine compartment and the car engine.

Description

The utility model relates to devices that conserve accumulated thermal energy, and can be used in various fields of technology, in particular, to maintain the thermal regime of an internal combustion engine after it is stopped and to facilitate subsequent engine starting.

The utility model can be used in the manufacture of auto blankets for insulation of the engine compartment and the car engine.

Known automotive insulation "AUTO HEAT" [patent for utility model RU 117519 U1, publ. 06/27/2012 Bull. Number 18. IPC F02N 19/00, application No. 20111134237, 08/15/2011], consisting of materials having heat resistance, fire resistance and low heat conductivity. In the insulation, fabric was used as the two extreme layers, a non-woven bulk fiber was used as the middle layer, all materials were made with an operating temperature of at least 500 ° C, the layers were connected to each other by needle-piercing.

A disadvantage of the known design is the fragility due to the ingress of dirt, dust and foreign objects into the unprotected end parts of the insulation.

Closest to the claimed technical solution is "Auto blanket - insulation of internal combustion engines" [utility patent RU 120720 U1, publ. 09/27/2012 Bull. Number 27. IPC F02N 19/00, F02B 77/11, application No. 2012115004, 04/16/2012], containing a closed volumetric cover made of refractory fabric, in which a non-woven volumetric refractory fiber is located between the fabric layers.

A disadvantage of the known device is the instability of the device, low reliability and durability associated with the possibility of spontaneous movement of the insulation inside the cover during installation, as well as with vibration of the blanket during operation of the covered engine and the movement of the vehicle.

The technical result of the proposed utility model is to increase the stability and reliability of the internal combustion engine of the vehicle due to the effective conservation of thermal energy.

The technical result is achieved by the fact that the auto blanket (automobile engine compartment heater) contains a volumetric closed cover made of refractory foil fabric, between which fabric layers there is a cellular cushion made of silicone rubber. The pillow cells are filled with a liquid coolant, providing greater heat capacity due to the operating temperature range from minus 65 ° C to plus 120 ° C. The cover along with the pillow is sewn with thread around the perimeter of the auto blanket and is additionally glued along the seam.

The auto blanket can be made in the form of a rectangle with two or four rounded corners and is stitched with a circumferential thread around the perimeter and additionally glued along the seam. This embodiment is suitable for most passenger cars, the hood of which has rounded corners.

The cover can be made of mulitosilica fabric, fiberglass, silica fabric or foil fiberglass. Between the layers of fabric is a cellular pad of silicone rubber with a liquid coolant. The firmware is fiberglass, gluing - high-temperature silicone glue. These materials are sufficiently heat-resistant and have high thermal insulation properties.

The auto blanket has the dimensions of the engine compartment.

The utility model is shown in figure 1: inside the cover of refractory foil fabric 1 is predominantly rectangular in shape, there is a cellular cushion made of silicone rubber, the cells of which are filled with liquid coolant (cushion with coolant - position 2). Some corners can be rounded. Along the perimeter of the cover there is a bypass line of firmware with sizing 3. The blanket is installed in the engine compartment of the car.

Improving stability and reliability is achieved by the fact that a liquid heat carrier based on water effectively absorbs the heat released during the operation of the internal combustion engine (ICE), accumulates it and, when the ICE stops, allows it to retain the accumulated amount of heat for a long time, preventing premature cooling of the engine.

Claims (3)

1. An auto blanket containing a voluminous cover of refractory fabric sewn around the perimeter by a thread, characterized in that the refractory fabric is made of foil glued along the seam, while between the layers of the refractory foil fabric there is a cellular cushion of silicone rubber, the cells of which are filled with a heat transfer fluid. 2. Car blanket according to claim 1, characterized in that it is made in the form of a rectangle with two or four rounded corners. 3. Car blanket according to claim 1, characterized in that glass fiber is used as a bypass thread.
