Description

[0001] HEAT EXCHANGER ASSEMBLY [0002]

The present invention relates to a plate type heat exchanger assembly, and more particularly, to a plate type heat exchanger assembly having a plate type heat exchanger having a recessed portion to enhance durability, to smoothly flow the heat exchange medium, To a plate heat exchanger assembly which is stably attached.

In recent years, interest in the environment and energy has been increasing worldwide in the automobile industry, and studies for improving fuel efficiency have been made. Research and development for lightening, miniaturization and high performance are continuously carried out in order to satisfy the needs of various consumers.

Particularly, in a vehicle air conditioning system, it is difficult to secure a sufficient space in the engine room. Therefore, the structure of the heat exchanger constituting the automotive air conditioning system is required to be compact and capable of improving efficiency.

1 is a view showing a conventional plate heat exchanger. The plate heat exchanger shown in FIG. 1 includes a first inlet pipe 10 through which a first heat exchange medium flows and a first outlet pipe (not shown) through which the first heat exchange medium is introduced; A second inlet pipe 30 through which the second heat exchange medium is introduced and a second outlet pipe through which the second heat exchange medium is introduced (not shown); And a plate (50) which forms a first fluid flow portion (51) and a second fluid flow portion (52) in which a plurality of first fluid exchange media and a second heat exchange medium flow alternately, respectively; .

1 shows an example in which the inner fin 60 is provided to increase the durability of the overall plate heat exchanger, and the two kinds of heat exchange media of the first heat exchange medium and the second heat exchange medium heat exchange with each other.

In the meantime, since the plate type heat exchanger is formed by stacking a plurality of plates and joining them, the first flow portion and the second flow portion are alternately formed in the stacking direction, so that when the stacking order is changed and stacked, the inner first heat exchange medium and the second heat exchange The flow of the medium may be formed differently, which makes it difficult to manufacture.

Particularly, such a problem is not immediately confirmed, and the heat exchange performance after the entire plate heat exchanger is manufactured, or the first heat exchanging medium and the second heat exchanging medium are mixed, and the total defect ratio is inevitably increased, This leads to deterioration of the composition.

In order to solve such a problem, JP-A-1997-089484 (name of the invention: plate heat exchanger) in which a marking portion is formed at the same position of the outer edge of the plate has been proposed.

Japanese Patent Application Laid-Open No. 1997-089484 discloses that although the left and right sides of a plate of the same type can be distinguished, it is necessary to identify and assemble markers formed on a plate of a thin material thickness one by one.

Meanwhile, when the heat exchanger is installed in the engine room, the heat insulating material is attached to the first heat exchanging medium and the second heat exchanging medium so that heat exchange can be smoothly performed without external influences without vibration or noise due to movement of the vehicle .

However, when the heat insulating material is attached to various types of heat exchangers for increasing the size and efficiency, there is a problem that a region of the heat exchanger not forming a plane forms a gap easily after the heat insulating material is attached.

The gaps move the condensed water generated on the surface of the heat exchanger (which is generated when the temperature of the heat exchanger is lowered), and the moving condensed water also lowers the adhesive force of the remaining adhered area.

When the heat insulating material is completely detached from the heat exchanger and contacts the other high temperature parts, a subject may be generated, which may be an obstacle to safety.

Accordingly, there is a demand for development of a plate heat exchanger assembly capable of improving the heat exchange performance by smoothly flowing the heat exchange medium, preventing the reverse assembly, and stably adhering the heat insulator.

A first inlet pipe 110 through which the first heat exchange medium is introduced and a first outlet pipe 120 through which the first heat exchange medium flows, a second inlet pipe 210 through which the second heat exchange medium flows, and a second outlet pipe 220 through which the second heat exchange medium flows, A first communication hole 301 and a second communication hole 302 which are respectively hollowed to be communicated with the first inlet pipe 110 and the first outlet pipe 120, A first fluid passage 410 in which a plurality of fluid passages are stacked and a first heat exchanging medium flows, respectively, and a third communication hole 303 and a fourth communication hole 304, And a second flow portion 420 through which the second heat exchange medium flows are alternately formed and the plate 300 having concave portions 310 and 320 formed therein inwardly concave such that both central portions thereof have a predetermined radius of curvature R310 and R320 A plate-type heat exchanger 1000 including the heat exchanger 1000;
A heat insulating material 2000 attached to surround the laminated plate 300 of the plate heat exchanger 1000;
And a tightening member (3000) tightly fixed to the heat insulating material (2000)
The plate-type heat exchanger 1000 has the plate 300 connected to the first communication hole 301, the second communication hole 302, the third communication hole 303, and the fourth communication hole 304, It is a curved curved surface shape,
Wherein the recesses (310, 320) on both sides of the plate heat exchanger (1000) have curvature radii (R310, R320) of different sizes.
delete The method according to claim 6,
The plate 300 is formed with first bonding portions 331 and 341 protruding upward or downward in the circumferences of the first communication hole 301 and the second communication hole 302, 303 and the fourth communication hole 304 are formed with second bonding portions 332 and 342 protruding in a direction opposite to the protruding direction of the first bonding portions 331 and 341,
A first plate 330 in which the first joint 331 is formed in a downward direction and the second joint 332 is formed in an upward direction,
Wherein the second plate (340) is formed by alternately stacking the first joint (341) in an upward direction and the second joint (342) in a downward direction.
