Description
The present invention relates to a plate type heat exchanger of plate shell that comprises the heat transfer plate of permanent connection, between heat transfer plate, be formed for the passage of at least two kinds of heat-exchange fluids.Each heat transfer strip interface holes, its () forms interface channel by the plate shell with the corresponding interface hole of other heat transfer plate.Plate type heat exchanger also comprises at least one connector, and this connector is used for linking to each other with a conduit, and one of described heat-exchange fluid flows to by this conduit or flows out plate type heat exchanger.Connector is connected with an external heat transfer plate of plate shell or a permanent therewith end plate that is connected by the permanent engagement mode.Connector has a through hole, wherein is provided with internal thread.This hole is communicated with one of described interface channel by the plate shell.
The heat transfer plate of this plate type heat exchanger forever connects each other by welding or brazing usually.In the heat transfer plate plate type heat exchanger interconnective by brazing, heat exchanger mostly is with two end plates, and they are brazed into two respective external heat transfer plates in the plate shell than heat transfer thickness of slab.Usually, one of end plate is provided with and the relative hole, interface channel of passing through the plate shell, and another end plate also is provided with one or more holes relative with above-mentioned interface channel.Connector is secured at least one end plate with brazing by the respective aperture around these plates with the form of pipe box usually.Each end plate needn't be made a member, and can be made by two or more members.
The passage that is used for heat-exchange fluid between the heat transfer plate is connected to the interface channel usually by this way, and promptly a kind of heat-exchange fluid will flow through each second channel, and correspondingly, this second channel is included in first group of passage.Rest channels forms one second group of passage, and other heat-exchange fluid will flow through this second group of passage.When plate type heat exchanger was in running, first kind of heat-exchange fluid flowed into first interface channel through first pipe box, again through first group of passage to second interface channel, and flow out through second pipe box.Second kind of heat-exchange fluid flows into the 3rd interface channel through the 3rd pipe box, flows out again through second group of passage to the four interface channel, and through the 4th pipe box.
During this plate type heat exchanger was used in a lot of fields, a field was the cooling of hydraulic oil.In hydraulic system, a heat-exchangers of the plate type is typically connected to low-pressure side.Hydraulic oil conduit on the low-pressure side of hydraulic system has a big relatively diameter, to obtain the as far as possible little pressure loss.And special jockey is used to connect the conduit on the different assemblies that are included in hydraulic system.The standing external screw thread that is equipped with of these jockeys when a plate type heat exchanger constitutes parts of hydraulic system, must be screwed into this jockey in the connector of plate type heat exchanger with external screw thread.Therefore, the connector of plate type heat exchanger must be provided with tapped hole.
Being used for the problem that hydraulic pressure plate type heat exchanger oil cooled, that have the jockey of internal thread pipe box form runs into is: when jockey was screwed into pipe box, the connection between pipe box and the end plate can be broken.The partly cause of the generation of this problem is to adopt big conduit diameter, and it correspondingly requires to adopt big jockey.This makes the major diameter pipe box on the plate type heat exchanger necessitate again.When jockey was screwed in the pipe box, major diameter can make described joint suffer big moment of torsion.In the past,, two parallel planes were set, and when jockey is screwed into pipe box,, can keep this pipe box securely by these two parallel planes in the outside of each pipe box in order to address this problem.Even now, the connection between end plate and the pipe box is also often broken.
The objective of the invention is to propose a solution of the above problems, it is better than the scheme that is proposed so far.
According to the present invention, adopt following scheme to achieve the above object.Described connector is the form with a contiguous block, and has an other through hole at least, described contiguous block is connected with described external heat transfer plate or described end plate, the second described interface channel that makes described other through hole and pass the plate shell links to each other, described permanent syndeton is extended around two through holes at least, therefore forms the syndeton of an antitorque turning stress between contiguous block and external heat transfer plate or end plate.This contiguous block is more much bigger than pipe box with the contact area of external heat transfer plate or end plate, thereby can form area coverage than much bigger in the past above-mentioned syndeton.
Therefore, when a jockey was screwed into plate type heat exchanger, syndeton can be born the moment of torsion that is produced definitely.
The result of big conduit diameter often is that at least one hole in the contiguous block must have a diameter bigger than the interface holes of plate type heat exchanger.Owing to according to contiguous block of the present invention, just can have the hole bigger, because in the past, the material thickness of two adjacent pipe boxes is a limiting factor to the aperture than previously possible aperture.
In one embodiment of this invention, described contiguous block is provided with internal thread in described other through hole.Therefore, this embodiment of the present invention makes two jockeys be screwed into a shared connector becomes possibility.
In the plate type heat exchanger of the embodiment one of according to the present invention, each described heat transfer plate has a width less than its length, its thickness is in the scope of 0.05-1.5mm, described contiguous block has one and strides across the whole width of heat transfer plate basically but only stride across the extension (size) of the partial-length of heat transfer plate, in addition, described contiguous block also has a thickness more much bigger than heat transfer plate.Thereby contiguous block only must cover portion of external heat transfer plate or the part end plate in the zone of a pair of interface channel.But the scheme that covers whole external heat transfer plate or end plate with contiguous block is compared economical with materials.
Advantageously, contiguous block has two parallel side, and when the through hole that is screwed into an externally threaded jockey in the contiguous block, it is as the position of tool holding contiguous block.
By means of accompanying drawing the present invention will be described in more detail.
