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 [F02N 17/00].

There are various devices and materials that store the accumulated thermal energy. For example, according to the certificate for utility model RU 34565U, a heater made in the form of a roll of mineral wool is known.

A disadvantage of the known insulation is that the mineral wool roll is not sheathed with fabric, which makes it impossible to use it for warming the car engine, since the cotton threads would touch over protruding parts and engine parts when installing and removing the insulation, which would quickly disable it . In addition, this will complicate the manipulation of staff when installing insulation on the engine.

Known automotive insulation according to patent RU 2148182, which is used for warming a car engine. Automotive insulation contains at least four layers of material: on the side adjacent to the engine parts there is a layer of material that is resistant to high temperatures, then a layer of insulation itself is placed, on the outside there is a protective material, a shield layer is placed between the insulation and the protection layer, reflective heat. Automotive insulation made for the engine of the ZAZ-1102 automobile consists of: the first layer is fiberglass, the second layer is batting, the third layer is a polyethylene film with metallization. The thickness of the second layer is 8 mm.

The disadvantages of the known automobile insulation are:

- the complexity of the design due to the use of four or more different materials in it, which makes it difficult to complete the production of materials;

- the unresolved issue of choosing a brand of fiberglass adjacent to engine parts;

- low heat resistance of batting, plastic film and synthetic leather, which reduces the durability of the shirt.

The closest solution is a car insulation (patent RU 64293U) containing a layer of fiberglass connected to a non-woven bulk fiber, characterized in that it contains the outermost layers made of fiberglass KT-11, between the layers of fiberglass is a non-woven volumetric fiber made of mineral mullite-siliceous cotton wool grade MKRP130, the insulation is stitched with a fiberglass thread.

Despite the elimination of the disadvantages of the above solutions in this device, the disadvantage is the presence of gaps in the engine compartment when using a heater. Those. heater prototype does not completely block the exit of warm air from under the hood. Insulation does not provide effective sound insulation of the engine also due to the presence of gaps. Also, the uniform distribution of the insulation under vibration throughout the entire life cycle is not ensured. In certain places, the insulation carries an additional vibration load.

The purpose of the utility model is to eliminate the disadvantages inherent in the prototype.

The technical result of the claimed utility model is a complete and uniform distribution of the insulation under vibration throughout the life of the unit. complete overlap of slots in the engine compartment and the exit of warm air from under the hood is completely blocked; Enhanced sound insulation of the engine.

The specified technical result is achieved due to the fact that the car insulation containing a layer of fiberglass brand EZ-200 with a density of at least 240 grams / meter, and between the layers of fiberglass is a non-woven bulk fiber made of mineral mullite-siliceous wool brand MKPP130, characterized in that it consists of from a protective cover, inside which two insulation mats are placed - wide and narrow, joined to each other in the fringe zone by the joint method and stitched through the cover, and the cover, wide and narrow mats stitched together with parallel seams of nylon threads and at least three along the perimeter.

Brief Description of the Drawings

Figure 1 shows the principle of the insulation assembly, where 1 is a cover, 2 is a narrow mat, 3 is a wide mat.

Figure 2 shows the insulation in the assembled state, where 4 - parallel seams of nylon threads, 5 - seam of the thread along the perimeter.

Figure 3 shows the method of docking mats with each other in the fringe zone by the joint method (a - docking method, 6 - firmware method).

Utility Model Implementation

Insulation materials (2, 3) are cut out on the basis of a protective cover (1) and a pattern. Insulators are placed inside the cover, they are joined in a special way and then stitched with nylon threads. The insulation is made on the basis of two mats - wide (3) and narrow (2).

These mats are joined to each other in the fringe zone by the joint method and are stitched through the cover. Thus, reinforcement occurs in this place in terms of strength and screed. The wide, narrow mats and the cover are stitched together with seams of nylon threads (4) and at least one seam (5) along the perimeter.

Insulation for the engine is a heat insulator of the engine compartment of the car, designed for use in the winter.

The use of insulation reduces the warm-up time of the engine and attachments to operating temperature. Thus, fuel consumption is reduced by accelerating heating, reducing the number of warm-ups and reducing the energy aimed at maintaining the operating temperature during driving. The stove effectively warms up the interior. Unwanted freezing of the car is prevented. This helps to avoid the costs associated with hiring a tow truck or express heating specialists. The likelihood of damage and failure of attachments during the freezing process is prevented.

To comply with all of the above qualities, the insulation must have a number of properties.

The heater is operated in conditions of sharp temperature drops from -50 (overboard) to +200 (in the area of the collector). Accordingly, the used threads, fabric and insulation must withstand this temperature range in order to avoid fire.

Insulation interacts directly with metals with very high heat transfer. Therefore, it is very important that it has the lowest possible thermal conductivity, as well as electrical insulating qualities to prevent short circuits.

The heater is used in chemically aggressive environments. In particular, it is in contact with fuel, process fluids.

The insulation is used in conditions of engine vibration, which should not affect its quality during the entire period of operation.

Work with a heater implies direct contact when installed in the engine compartment. In this aspect, it is important that the use of insulation does not imply the need for protective equipment.

The insulation is located in the engine compartment, which also has an air intake through which air from the street enters the car interior. This implies the need for non-toxic materials in the composition of the insulation. Moreover, it is necessary to avoid getting insulation in the air intake, in order to protect the lungs of the driver and passengers. The outer fabric should be sufficiently dense and not have any scoring.

In accordance with its purpose, the insulation must block the exit of warm air from under the hood. Ineffective use of insulation that does not match the dimensions of your engine compartment. Any slots will negate the entire usefulness of the insulation.

To ensure these properties, the claimed insulation is made of fiberglass grade EZ-200 high density, which has low thermal conductivity, has excellent electrical insulation properties. This fiberglass is designed for long-term use in temperatures up to 600 ° C and more, which allows you to use it even in direct contact with the collector. EZ-200 (240 g / m) provides the best thermal insulation at high temperatures. Importantly, these fabrics are completely safe for human health. EZ-200 (240 g / m) has a high density, which excludes the release of insulation into the engine compartment and, as a result, getting into the car interior. Due to the high density of the fabric, the need to use personal protective equipment when in contact with it also disappears.

As insulation, kaolin wool (mineral mullite-siliceous wool brand MKRP-130) is used. The fibers of this insulation are resistant to acids and alkalis, have good electrical insulating and refractory properties. This material also gives off elasticity, resistance to vibrations and deformations. Moreover, kaolin wool provides additional sound insulation of the engine compartment and, of course, is completely non-toxic. From it there are no extraneous odors in the cabin.

Due to the presence of transverse parallel seams, uniform distribution of the insulation under vibration conditions is ensured over the entire service life. Threads used for firmware - 4 mm nylon thread (Euronite, EURON). The engine compartment of a car in 95% of cases is as follows. The main place is occupied by the engine area of 60-70 centimeters, then there are voids and a radiator behind them. During the operation of the car and vibration from the engine, the heater displaces inside the auto blanket in the void zone, since the auto blanket in this zone literally “hangs”, the insulation often breaks in the case, or it spills, or the heater accumulates in one area of the auto blanket to the detriment of other zones , which creates a heat release area. The utility model allows not only to keep the insulation inside in the right place, but thanks to a special docking, it does not allow tearing and crumbling. The vibration load is transferred not to the entire area of the insulation, but to a specific area, which is reinforced by the stitched joint of two mats. Thus, the breakdown of the insulation inside the auto blanket into two mats, assembled according to the claimed utility model, can withstand the load from vibrations, maintain the integrity of the insulation, and prevent it from crumbling. One mat is sized for the engine and the second according to the dimensions of the voids and radiator.
