Description

Compound condenser of cooling air and water

The present invention relates to a combined condenser combined with air cooling and water cooling.

The heat exchanger is installed on a heat exchange medium flow path of a cooling and heating system, and the heat exchange medium flowing therein heats and heats the external air or heats its own heat to the outside to cool and heat a predetermined space.

Here, in the cooling system for cooling the room, the refrigerant in the gaseous state in the compressor is compressed into a gaseous state of high temperature and high pressure, which is liable to be liquefied, and is transferred to the condenser. Is transferred to the valve.

Subsequently, in the expansion valve, the refrigerant phase-changed into a liquid state is changed to a low-temperature, low-pressure wet saturation steam state by the throttling action, and is transferred to the evaporator. ), It evaporates itself, changes to gaseous state, and then repeatedly enters the compressor.

The condenser constituting the cooling system, a variety of air-cooled and water-cooled condensers of various types in order to increase the heat exchange efficiency, Japanese Patent Laid-Open No. 2008-180485, Korean Patent Publication No. 1998-0010245, Korean Patent Publication No. 1998-0073360, Korean Patent Publication No. 2000-0032401.

The Japanese Laid-Open Patent Publication No. 2008-180485 discloses a sub-radiator in a system in which cooling water cooled from a sub-radiator is sent to a water-cooled condenser and heat-exchanged with the high-temperature high-pressure refrigerant discharged from the compressor, and then these refrigerants are sent back to the air-cooled condenser. Although the water-cooled condenser and the air-cooled condenser are integrally formed, there is a problem in that the header of the sub-radiator and the header of the water-cooled and air-cooled condenser are different, and the assembly properties and weldability of the joint are inferior.

The Korean Laid-Open Patent Nos. 1998-0010245, 1998-0073360, and 2000-0032401 are all integrated condensers combined with air cooling and water cooling.

In addition, the vehicle is equipped with an oil cooler separately for cooling the oil used for lubrication and airtightness of the engine or transmission. However, as the oil cooler is composed of separate parts as described above, the production labor is increased, the productivity is lowered, the manufacturing cost is increased, and there is a problem in securing a space for installing the oil cooler.

In order to solve such a problem, the technology of integrating an oil cooler with a condenser is disclosed in Korean Laid-Open Patent No. 2004-0099997, Korean Laid-Open Patent No. 2006-0011204, Korean Laid-Open Patent No. 2006-0056260, and Korean Registered Patent No. 0644134, Japanese Patent Laid-Open No. 2005-140463 or the like.

The Korean Laid-Open Patent Publication No. 2004-0099997 has a heat blocking plate for blocking heat transfer between a condenser and an oil cooler, and a supporting means is provided inside each header pipe to insert or seat a heat blocking plate.

The Korean Laid-Open Patent Publication No. 2006-0011204 is a heat exchanger integrating a condenser, a transmission oil cooler and a power steering oil cooler, and the first, second, and third independent of the inner space of the left and right header pipes in the vertical direction. It is a structure provided with the partition means which partitions so that space part S1, S2, and S3 may be formed.

Korean Patent Laid-Open Publication No. 2006--0056260, wherein the first header pipe includes a cutout portion positioned between a pair of first baffles, and the cutout portion is formed by cutting the first header pipe laterally. .

The Korean Patent No. 0644134 discloses that a plurality of baffle plates are installed at predetermined boundaries at the boundary between the condenser and the oil cooler inside the first and second headers to minimize heat transfer from the oil cooler to the condenser. The heat transfer prevention grooves or holes are formed in the header pipe portion between the baffle plates.

The Japanese Laid-Open Patent Publication No. 2005-140463 has a configuration in which the header pipes of the condenser and the oil cooler, which are separately manufactured, are connected through a connecting member to be modularized or integrated.

However, the conventional air-cooled and water-cooled integrated condenser both have a problem of common use and standardization of parts, and the Korean Patent Publication No. 1998-0010245 is constrained by vehicle mounting due to widening of the condenser because the tubes are arranged in two rows. There is a problem, and Korean Patent Laid-Open Publication No. 1998-0073360 distinguishes a coolant and a coolant flow path in a tube cross-sectional flow path, but there is a problem that technical difficulties are followed in separating the coolant and the coolant from the header. The arc differs from the header of conventional condensers and suffers from a poor weldability of the joints between them.

In addition, in the conventional oil cooler integrated condenser, the installation position of the inlet / outlet pipe and the pipe connection block for the condenser are different depending on the position where the oil cooler is placed relative to the condenser, and also varies depending on the applied vehicle. There was a problem that the publicization and standardization of.

In addition, in the conventional oil cooler integrated condenser, the position where the oil cooler is placed on the upper or lower portion of the condenser is restricted. It is difficult to install efficiently and economically as in most cases, and nowadays, most vehicles have an external oil cooler installed in parallel at the desired position in front of the condenser. Therefore, in this case, the vehicle occupies a space before and after the vehicle, and the cooling efficiency of the refrigerant decreases at the condenser in which the oil cooler is located. There was a problem with being thrown.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to simplify the condenser by reducing the manufacturing cost and increase the cooling efficiency by making common use and standardization of parts, the oil cooler in the intermediate position of the condenser It is an object of the present invention to provide a combined condenser for both air-cooling and water-cooling that can be easily integrated with a condenser.

A plurality of baffle members are provided between the first passage and the second passage so as to divide directions and sections; The plurality of tubes forming the heat exchange core part may include a first tube configured to communicate a first passage of the first header with a first passage of the second header, a second passage of the first header, and a second header of the second header. Divided into a second tube communicating two passages; The heat exchange core part TC may include a second heat exchange part TC2 in which cooling water and air are exchanged with each other by the second tube, and a mixture of the first tube and the second tube so that the refrigerant, the cooling water, and the air are heat exchanged with each other. Oil is introduced into a mixed heat exchanger TC3, a first heat exchanger TC1 through which the refrigerant and air are exchanged with each other by the first tube, and a position between the second heat exchanger and the mixed heat exchanger.

Can reduce the manufacturing cost. In addition, by applying one kind of header, it is possible to easily share and standardize components, and conventionally, there is no problem in assembly property or weldability of joints generated between different headers.

In the heat exchange core part, since the coolant that is heat-exchanged with the refrigerant exchanges heat with the refrigerant while heat-exchanging with the refrigerant through the heat radiating fins, the cooling performance or the cooling efficiency can be increased. In addition, even if a problem occurs in the cooling water supply device, the refrigerant can be sufficiently cooled by air, so that the desired cooling performance can be easily obtained, and since the cooling efficiency is high, the condenser can be miniaturized.
