Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The utility model provides a plate heat exchanger with high-efficient heat transfer slab of four V-arrangement ripples, heat exchanger include a plurality of middle slab that are stacked together upside down and be located terminal end plate, the utility model discloses a slab pile up the mode, the method of assembling into the heat exchanger all is the same with prior art, distinguishes and lies in: the middle plate and the end plate are all four V-shaped heat transfer plates.

As shown in fig. 1, the middle part of the four V-shaped heat transfer plate is a corrugated area 1, corner holes 6 are arranged at four corners of the four V-shaped heat transfer plate positioned on the middle plate, and the two corner holes at the same side on the left and right are an inlet and an outlet of the same medium; the two angle holes on the upper and lower same sides are heterogeneous angle holes. The four V-shaped heat transfer plates also comprise a flow guide area 3; the flow guide areas are symmetrically arranged on the upper side and the lower side of the corrugated area and are positioned on the same side with the homogeneous angle holes. The diversion area is used for guiding the medium flowing out of the corner hole into the diversion area. However, since the homogeneous and heterogeneous corner holes are located on the board surface, care is required to separate the heterogeneous corner holes from the homogeneous corner holes.

Be separated by between the heterogeneous angular hole and have the sealing strip, it is specific, the sealing strip is located heterogeneous angular hole's all around to and between heterogeneous angular hole and the diffluence district, so two-layer sealing strip can guarantee not to obscure between two kinds of media.

The flow guide channels on the corrugated area are in four parallel V shapes, and compared with the prior art, the four V-shaped heat transfer plates have higher heat exchange efficiency. Because the four V-shaped flow channels are more tortuous, the contact area of the medium is increased when the medium passes through the four V-shaped flow channels, the medium impacts on the flow channels, and large turbulence is caused to the medium, so that the heat exchange efficiency can be improved.

However, in order to avoid the increased resistance, the included angle of each V-shaped flow channel is set to be 40-60 degrees, when the medium impacts the flow channel wall, the medium can more easily descend along the flow channel wall, and therefore the resistance suffered by the medium in the flowing process is reduced.

The ripple district has the width, and in a general reason, the ripple district that is close to the angular hole preferentially receives the medium, because medium flow relies on gravity in the plate heat exchanger, consequently will cause the regional receipt far away from the angular hole few, can not receive the medium even to the medium is at the maldistribution in ripple district, causes the medium to obtain abundant heat transfer, makes heat exchange efficiency low.

Therefore, the upper and lower sides of the corrugated area are symmetrically provided with the shunting areas 2. The purpose of the diverter zone is to divert the media to ensure that the amount of media entering each portion of the corrugated region is even.

The flow distribution area is in a herringbone shape, the middle part of the herringbone shape is higher, and the side edge of the herringbone shape is longer, so that the medium can be uniformly distributed. The diversion runners on the diversion area are mutually crossed to form a net shape, each diversion runner is bent downwards, and the gradient of each diversion runner is gradually reduced from the middle part of the diversion area to the two sides in a extending way; when the medium passes through the flow channel with the large gradient, the medium can generate gravity acceleration compared with the flow channel with the small gradient, so that the medium can be promoted to flow farther, and the purpose that the medium can be received by the long-distance flow channel is realized.

In addition, in order to ensure that the medium can advance along the flow channel, a plurality of bumps 4 are arranged between two adjacent flow guide flow channels and extend along the flow channel direction, so that the flow channel is deepened.

As shown in fig. 3, the left and right sides of the four V-shaped heat transfer plates are provided with a plurality of grooves, a protrusion 5 is arranged between two adjacent grooves, and the grooves and the protrusions between two adjacent corrugated heat transfer plates are nested with each other. When a plurality of plates are stacked, the spaced grooves and the spaced protrusions can form a nested structure, so that the plurality of plates are combined more tightly, and the grooves and the protrusions are matched to form a locking structure, so that the plates can be aligned, and the problem of leakage caused by inclination of the plates in the assembling process is solved.

The above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples, and the technical personnel in the technical field are in the present invention, which can also belong to the protection scope of the present invention.
