The present invention relates to a heat exchanger having a temperature difference, that is, a fruit having a temperature higher or lower than the atmosphere, through a predetermined flow path and heat-exchanging the atmosphere by endotherm or radiation by forced convection. The present invention relates to a laminated heat exchanger capable of improving the composition.

BACKGROUND ART A multilayer heat exchanger is commonly used mainly in an air conditioner of an automobile, and such a multilayer heat exchanger has been developed and used in various ways.

The laminated heat exchanger is formed by stacking the unit members of the tank and joining the unit members in a brazing manner with the sides adjacent to each other, and interposing the heat transfer fins between the unit members, and defining the fruit inside these. The unit member is manufactured by a suitable pressurization process using aluminum or a suitable material having excellent thermal conductivity.

More specifically, the unit member is composed of a pair of plates, the plate is a body having a rectangular plate shape, having at least one passage portion, they are arranged in parallel in the same plane along the longitudinal direction of the plate.

The passage portion serves as a first passage portion, a second passage portion and a third passage portion along the direction of the flow path of the fruit, wherein each passage portion is separated by an adjacent side and a separation wall.

In addition, the right and left ends of each passage portion have a through hole through which the body of the plate is pushed down to pass or pass the fruit.

The through hole is provided only in the passage or is jointly installed in the adjacent passage portion, and a protrusion is provided in the passage portion to obtain the heat transfer and simultaneous turbulence effect of the fruit.

The plate thus constructed is joined to the mating plate with each other by fusion bonding to form one unit member, and the unit members are stacked in a stacked manner to be coupled to the unit members on the adjacent side as described above.

At this time, a space is provided between each unit member, and a heat transfer fin is interposed in the provided space, and heat exchange is performed with the fruit while forcibly blowing air into them.

However, the performance of the heat exchanger is determined by the flow of fruit, that is, the heat transfer time or flow path of the fruit, and the flow of fruit is very important in the heat exchanger.

The fruit flow is overcome by the plate of the unit member, and the position of the passage portion or the through hole provided in the plate is changed to provide the fruit flow path.

Various proposals have been made regarding the method of returning such fruit.

However, the fruit flow is not effectively achieved, and heat exchangeability is poor. In other words, the flow path of the fruit is not effective, for example, the flow length is short and heat loss occurs because the flow length is short or does not form a path suitable for the blowing direction. Rather, the difference in the time that fruit is circulated from the inlet side to the outlet side is large because the heating zone applied to the heat exchanger does not have a uniform heat transfer temperature zone in the area of the heat exchanger facing the blowing direction. Therefore, there is a problem in that there is a large temperature difference on the inlet / outlet side thereof, and the heat transfer value or a large difference of the blowing air passing through these drops the heat exchange, thus affecting the air-conditioning.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a laminated heat exchanger having an effective heat flow path for maintaining an entire heat transfer temperature band equal to the entire area of a heat exchanger.

Another object of the present invention is to provide a laminated heat exchanger having a plurality of flow paths in a cross direction opposite to blowing.

Another object of the present invention is to provide a laminated heat exchanger having two stages of fruit flow path by dividing the body of the heat exchanger into upper and lower parts.

The object of the present invention is achieved by providing a heat exchange mechanism for achieving a heat exchange, that is, using a unit member having a fruit flow path, which heat exchange mechanism has a unit member in which a water tank is laminated by welding, Has a pair of plates that are welded with at least one passage in parallel, and the passage also has apertures in the upper and lower tanks at its front and rear ends, the apertures of either of which are adjacent to each other. It is provided with a common hole used to communicate with each other through the passage of the passage.

The plates are symmetrically abutted to form one unit member, and the unit members are hydrothermally laminated to form a heat exchanger.

At this time, the heat exchanger is divided into the upper and lower parts with the center of the body height direction as the center so that the installation direction of the unit member is installed in the direction opposite to each other in the longitudinal direction of the body, and thus the area of the heat exchanger facing the fruit in the blowing direction. The flow path that flows in two stages on the plane of the buoy has a sequence of water in the direction of blowing.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In addition, the passage part 211 performs the first passage, the second passage and the third passage along the flow direction of the fruit.

More specifically, the sequence is determined from the inflow direction of the fruit, the passage portion 211 is also in direct contact with the fruit flowing therein the projection 213 to promote the endotherm or radiation of the fruit at water tank equal intervals Arrange the fruit flow as well as heat exchange.

In addition, each passage portion 211 is provided with a through hole 214 for the entry and exit or passage of the fruit in the passage portion of the passage portion, the through hole in the upper and lower tanks (200a) at both ends of the passage portion ( 200b).

Such a through hole 214 is provided only in the passage portion 211, or constitutes a common hole 215 used to communicate with each other through the through hole of the adjacent passage portion of any one of those through holes.

The through hole 214 is pushed down the plate 210 is installed slightly lower than the passage portion 211.

This plate 210 may be manufactured through a suitable pressurization process using a suitable material having excellent aluminum or thermal conductivity.

After the plates 210 are configured to be symmetrically butted to contact each other, one unit member 200 is configured by fusion-bonding suitable heat.

Then, the unit members 200 configured as described above are stacked and bonded to adjacent unit members. At this time, a space for passing heat exchange between the unit members 200 is provided to the heat exchange, the heat transfer member 300 is provided in the space and the direction of the air flow progress.

The heat transfer member 300 is composed of a thin plate having the same width as the width of the plate, the heat transfer member is installed in the space between the plates in the shape of a wave within the width of the space and passed into the atmosphere or heat transfer member The heat is radiated or endothermic.

Except for the closing portion 216, the through hole is used as the inlet and outlet of the fruit is used in these directions are symmetrical with each other on the upper and lower sides of the heat exchanger.

In addition, the plate 210 of the unit member 200 which is opposed to each other at the center portion of the heat exchanger 100, that is, the separating portion divided into upper and lower groups, is also the same as the above through hole 214 and common hole 215 of the The through hole 214 and the common hole 215 are constituted by the turn part 217.

At this time, they are installed in positions opposite each other.

Next, the operation of the inventive heat exchanger 100 will be described in detail with reference to FIGS. 5 and 6.

When the fruit is introduced through the passage 214 provided as an inlet portion on the heat exchanger 100 (see arrows in FIG. 5), the through hole is provided in the passage portion 211 having no common hole 215.

And the passages are installed in the same vertical line to the lower portion of the through hole 214, the fruit flows in the flow path in the horizontal direction in the passage portion 211 on one side of the unit member 210 of the upper group as shown in FIG. .

The flow of fruit will be described as forward or backward for convenience.

And the fruit passing through the upper unit member 210 is a through hole 214 provided in the lower unit member 210, the through hole is located outward of the passage portion 211 having a common hole 215 The passage portion is provided.

Thus, as in the above of the fruit supplied from the upper group, the lower unit member 210 temporarily flows in the horizontal direction, and the flow direction thereof is reverse to the upper group.

So far, the description has passed through the first passage.

In addition, when the fruit flows forward from the rear unit member 210, the unit member 210 is provided with a common hole 215 will flow the fruit to the second passage.
