Description

A heat exchange frame having a diffusion support and a vehicle heat exchanger including the same

The embodiment relates to a heat exchanger. Specifically, the heat exchanger of the embodiment may be for a vehicle oil cooler, but is not limited thereto.

A heat exchanger transfers heat from a high-temperature fluid to a low-temperature fluid through a heat transfer wall, and is used in heaters, coolers, evaporators, and condensers.

Such a heat exchanger reuses energy or adjusts the temperature of an incoming working fluid according to its purpose, is usually applied to an air conditioning system of a vehicle, a transmission oil cooler, etc., and is also installed in an engine room.

On the other hand, as a prior patent document of a heat exchanger applied to an engine for a vehicle and an automatic transmission, there is a prior patent document 1 (KR10-2012-0055830A, published on June 1, 2012) and 'Structure of a water-cooled oil cooler for a vehicle'.

According to the preceding patent document 1, the engine and the automatic transmission are mounted in the engine room in a coupled state, and engine oil and automatic transmission oil (AT oil) are respectively injected for proper lubrication of the engine piston and the torque converter.

In order to cool the engine oil and the automatic transmission oil, separate coolers are installed in the engine and the automatic transmission to prevent the temperature of the oil from rising. In the water cooling method, coolers through which oil flows for cooling and warming up are installed in the engine and automatic transmission, respectively, and the cooling is performed using heat exchange between the engine coolant and oil.

The water cooling method is a method in which the coolant circulating in the engine additionally exchanges heat with engine oil and automatic transmission oil. do.

Meanwhile, in the applicant's internal technology, an oil referred to as an automatic transmission fluid (ATF) is used for an automatic transmission (AT).

In general, engine oil is used in a high-temperature combustion environment called an engine accompanied by a high temperature.

On the other hand, automatic transmission oil is not used in a high-temperature combustion environment, but in the automatic transmission, in addition to the lubrication function, it must maintain the required frictional force when the clutch is engaged. It is an important oil that should also function as a motor, but automatic transmission oil is very sensitive to temperature.

1A is data of viscosity (V: Viscosity) according to temperature (T) of an automatic transmission oil.

Automatic transmission oil requires properties such as high viscosity, abrasion resistance, oxidation stability, appropriate friction properties, and corrosion resistance. In particular, maintaining 'high viscosity' is considered a key technical characteristic.

However, according to FIG. 1A , it can be seen that the viscosity (V) of the automatic transmission oil rapidly decreases as the temperature (T) increases. According to the 'low viscosity' of the automatic transmission oil, the oil film of the oil becomes thinner, and the wear resistance that prevents wear of gears, bearings, hydraulic pumps, etc. may deteriorate, and the fatigue life of metals may deteriorate.

In particular, due to the 'low viscosity' of the automatic transmission oil, it is difficult to operate the automatic transmission properly because it fails to maintain the 'appropriate friction characteristics' that reduce shift shock when the clutch is connected and prevent excessive slippage.

1B is heat distribution data of oil in an oil cooler of an automatic transmission (AT) for an electric vehicle in the applicant's internal technology, and the central arrow is the overall flow direction of the AFT.

The applicant has discovered through unpublished research that there is a problem in that the oil is not uniformly cooled in the oil cooler of an automatic transmission (AT).

In particular, because the amount of movement of the AFT on the outer periphery of the cooling frame or heat exchange frame of the oil cooler is relatively large, the ATF on the perimeter of the outer perimeter has a small contact area or contact time with the coolant, so it is discharged without being cooled properly and supplied to the automatic transmission. has been studied, and these problems are undisclosed technical problems, but have not been properly resolved.

Due to this problem, as the temperature of the designed AFT is supplied to the automatic transmission, the AFT in a 'high temperature and low viscosity state' is supplied to the automatic transmission, which deteriorates the wear resistance and reduces the fatigue life of the metal. The inventors of the applicant have derived a special technical problem in which it is difficult for the automatic transmission to operate properly due to the failure to maintain the friction characteristics.

Next, Figure 1c is a partial cross-sectional view of the automatic transmission oil cooler in the prior art.

According to the prior art, a plurality of baffles (B1, B2, B3, B4, B5, B6) is formed in a baffle structure (B) in which a cooling frame or a heat exchange frame is stacked, in which case a predetermined jig is formed after the plurality of baffles are stacked. (not shown), the process of being integrated through the compression process proceeds.

However, as shown in Figure 1c, when the baffles are pressed by a strong compression force through such a jig, the dimension (D2) is lower than the original design value (D1), or the distance between the baffles is different from the actual value (D1). D3, D4) may occur, and the cooling frame may be damaged because it cannot withstand the pressure (refer to B5).

On the other hand, when the jig pressure is applied low to prevent product damage, the baffles are not properly compressed, and thus the technical inconsistency of coolant or oil leakage or oil leakage occurs. derived.

Patent Document 1_Publication Number: KR10-2012-0055830A, Publication Date: 2012.06.01, Title of Invention: Structure of a vehicle water-cooled oil cooler

One of the technical challenges of the embodiment is that the AFT in a 'high temperature and low viscosity state' as the AFT is supplied to the automatic transmission in a state higher than the designed temperature in a state where it is not cooled properly on the periphery of the cooling frame of the oil cooler or the heat exchange frame. This is to solve the problem of poor wear resistance, deterioration of metal fatigue life, and inability to maintain proper friction characteristics in an automatic transmission, which makes it difficult to properly operate the automatic transmission.

In addition, one of the technical problems of the embodiment is that, when the oil cooler is pressed by a strong compression force in a stacked structure of a plurality of cooling frames or heat exchange frames, the dimensions may be lower than the design value, or product defects may occur, and the cooling may not withstand the pressure. There is a problem that the frame is damaged. To prevent damage to the product, if the pressing pressure is applied low, it is not compressed properly. This is to solve the technical contradiction in which coolant or oil leaks or leaks occur.

The technical problems of the embodiment are not limited to those described in this item, and include those that can be derived through the specification.

The heat exchanger for a vehicle according to an embodiment may include a heat exchange frame including any one of the diffusion supports.

According to the heat exchange frame having a diffusion support according to the embodiment and the vehicle heat exchanger including the same, the temperature of the AFT designed to be not properly cooled by riding on the periphery of the cooling frame of the oil cooler or the heat exchange frame is higher than that of the automatic transmission. As it is supplied, AFT in 'high temperature and low viscosity' is supplied to the automatic transmission, which deteriorates the wear resistance, reduces the fatigue life of metal, and in particular, the automatic transmission fails to maintain proper friction characteristics. can be solved
