Description

 Separable Radiator

The present invention relates to a detachable radiator. More particularly, the present invention relates to a detachable radiator in which a plurality of plate portions, in which a tank and a tube are integrally formed, are assembled into a sub-block through a welding process,

Generally, in a vehicle equipped with an internal combustion engine, heat generated during operation of the engine is transmitted to a cylinder head, a piston, a bail or the like. As a result, if the temperature of these components excessively increases, the strength of the component decreases due to thermal expansion or deterioration. The life span is shortened and the combustion state is worse, knocking or early ignition occurs, and the output of the engine is also lowered.

In addition, when the cooling of the engine is incomplete, the lubricating function of the oil film on the inner circumferential surface of the cylinder is lowered. In addition, the engine oil is deformed to cause abnormal wear of the cylinder and the piston is fused to the wall surface of the cylinder .

In order to prevent the engine from overheating and maintain the proper temperature, a water-cooled cooling device is used in which the engine is cooled by circulating water through a cooling water passage surrounding the cylinder and the combustion chamber.

The water-cooled type cooling device lowers the temperature of the cooling water circulating through the cylinder block and the cylinder head by a water pump, and includes a radiator, a cooling fan, and a water temperature controller for radiating the cooling water.

The water-cooled type cooling apparatus includes a water jacket surrounding the cylinder and the combustion chamber; A water pump that pumps and circulates water into the cylinder, a radiator that cools the heat of the coolant with high temperature to the outside air, a fan that helps ventilate the radiator, and a thermostat to raise the coolant to the proper temperature immediately after startup have.

The radiator is a kind of heat exchanger that cools the overheated engine. The heat exchanger is a typical example of a condenser used in an air conditioning system, a vaporizer, and a radiator used for engine cooling.

Among these heat exchangers, the condenser and the evaporator heat the refrigerant required for the air conditioner to heat exchange with the latent heat in the high-temperature and high-pressure state or the low-temperature and low-pressure state to liquefy the refrigerant or generate the cold air due to evaporation. In the case of the radiator, The cooling water that has been heated to a high temperature is converted into a low-temperature state by heat exchange with surrounding latent heat.

1 is a perspective view showing a radiator according to a conventional technique.

As shown in FIG. 1, the radiator 1 according to the related art includes upper and lower tanks 2 (4) horizontally installed so as to be spaced up and down; Upper and lower headers 3 and 5 which are joined to the open surfaces of the upper and lower tanks 2 and 4 to form a closed cooling water flow space; A plurality of tubes (6) arranged vertically between the upper and lower headers (3, 5); And a radiating fin (7) interposed between the tubes.

However, since the conventional radiator uses a synthetic resin material as the material of the tank, the lower tank of the radiator, which is relatively influenced by calcium chloride and foreign matter, is corroded due to the introduction of the calcium chloride used for the snow removal into the engine room of the vehicle. There is a problem that breakage frequently occurs at the joint portion with the tube portion and breakage occurs at the tank itself.

And a process for joining the injected plastic tank with the header is added, resulting in lower productivity and higher cost.

In recent years, an aluminum material tank made of a brassiere method has been used to overcome such disadvantages. Such a tank is easy to recycle, has strength and requires no additional process. However, the attachment of the tank, that is, Parts such as pipe, pressure cap neck, body support pin, fan shroud bracket, etc., must be assembled separately, so that not only the cost is increased by the attachment, but also the advantages of the aluminum tank can not be fully utilized There is a problem.

The present invention has been conceived to solve the problems of the prior art described above, and it is an object of the present invention to provide a sub-block in which a plurality of plate portions are welded to manufacture a radiator, And to provide a separate type radiator that secures the radiator.

Another object of the present invention is to provide a detachable radiator that can replace only a damaged part when the radiating fin or the tube is damaged, thereby reducing the repair cost of the customer.

The separable radiator according to the present invention comprises a plate provided with a rod inside and vertically spaced up and down by an upper tank and a lower tank, a plate part integrally formed with tubes arranged vertically between the upper and lower tanks, A cooling water flow passage in which a plurality of the plate portions are welded to each other to form a sealed space in which cooling water flows between the upper and lower tanks and the tube, And a sub-block formed by welding a plurality of plate portions formed with the cooling water flow path as necessary according to the size of the radiator.

And the heat dissipation fins are separated from each other without being welded to facilitate disassembly and attachment of the plurality of subfloors.

 And the radiating fins are uneven pitch-shaped.

The inside of the tank is in the form of a corrugated tube in order to increase the overall strength of the radiator and to prevent thermal deformation.

Further comprising a flow guide portion disposed inside the tank to prevent flow resistance that may occur due to the shape of the corrugated tube and induce laminar flow inside the tank.

The connection between the sub-block and the fan includes a mounting clip that is fitted to the tank and is provided to be movable according to the size of the radiator.

The mounting clip includes a flow preventing groove having a groove formed in the inside of the mounting clip to facilitate flow prevention and detachment.

Both ends of the upper and lower tanks include a rod nut which is fastened to both ends of the rod for disassembly and coupling of the sub-blocks.

And an O-ring portion disposed on one side of the upper and lower tanks of the sub-block to prevent cooling water from leaking on the connection portion of the upper and lower tanks between the sub-blocks by a force compressed by the rod.

The plate portions disposed at both ends of the sub-block are different in outer shape of the upper and lower tanks so that the cooling water inflow pipe and the cooling water discharge pipe are disposed, and the rest are the same shape.

        [0001] The present invention relates to a detachable radiator, and more particularly, to a detachable radiator, which comprises a tank provided with a rod therein and vertically spaced vertically by an upper tank and a lower tank, a plate portion integrally formed with tubes vertically disposed between the upper tank and the lower tank, A cooling water channel in which the plate portions are overlapped in a left-right direction and a space in which the cooling water flows between the upper and lower tanks and the tube by welding a portion where a plurality of the plate portions are in contact with each other, And a sub-block formed by welding a plurality of the plate portions formed with the cooling water flow path as needed according to the size of the radiator, thereby significantly reducing the number of complicated processes and parts in manufacturing the radiator, securing the quality stability of the product, When the tube is damaged, It is possible to replace blocks only, which saves customers repair costs.

Also, in developing a new car, it is required to develop a new radiator according to the package. By connecting the sub-blocks to only the required number of sub-blocks, it is advantageous to increase the degree of freedom of design.

In addition, there is an advantage that the range of the common use is wide so that the vehicle can be used from a small-sized vehicle to a medium- and large-sized vehicle.

In addition, when the heat radiating fins or the tube are damaged, if the sub-block is replaced, the remainder can be reused.

In addition, there is an advantage that it is convenient to recycle and exchange parts by using only a single piece of aluminum.
