Embodiment Construction

[0029] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings. The embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0030] The plate heat exchanger of this embodiment includes an upper end plate 3, a lower end plate 4, and a series of heat exchange plates 2 neatly laminated between the upper and lower end plates, and a heat exchange flow layer is formed between adjacent heat exchange plates 2, which are relatively Adjacent heat exchange fluid layers do not interfere with each other, and the heat exchange fluid layers through which two heat exchange fluids flow are arranged alternately up and down, that is, all heat exchange fluid layers serving the same heat exchange fluid are arranged at intervals. Furthermore, each heat exchange plate 2 includes a flanging, a heat exchanging area and four corner holes 1, and through t...

Abstract

The invention relates to a long flow plate heat exchanger which comprises an upper end plate (3), a lower end plate (4) and serial heat exchange plates (2) laminated orderly. Each heat exchange plate(2) is provided with four corner holes, the same corner hole penetrates up and down to form a channel, and the four channels in pairs are matched with two heat exchange fluids and communicate to the matched heat exchange flow layers correspondingly. Two channels corresponding to the same heat exchange fluid are taken as a distributing channel (20) and a heat exchange channel (31), separately, wherein the distributing channel (20) is divided into a lower flow inlet cavity (20b) and an upper flow outlet cavity (20a), and correspondingly, the heat exchange flow layer communicating to the distributing channel (20) is divided into primary heat exchange flow layers (7, 8) and secondary heat exchange flow layers (9, 10), and the primary heat exchange flow layers (7, 8) and the secondary heat exchange flow layers (9, 10) are in turning communication through a flow exchange channel (31). According to the long flow plate heat exchanger, the same heat exchange fluid flows in and out of the same corner hole, and the structure of the plate heat exchanger is simplified in shape.

Description

technical field [0001] The invention relates to a plate heat exchanger, in particular to a long flow plate heat exchanger with simple appearance. Background technique [0002] In the field of engines, oil coolers in the form of plate heat exchangers are often used, such as Weichai automobile engine oil cooling, using cooling water to absorb the heat carried by the engine oil in two staggered and mutually isolated flow channels, and the second fluid engine case oil Refrigeration. As a part of the engine components, the engine oil cooler generally requires miniaturization, light weight, and high reliability to meet the requirements of effective heat exchange and convenient installation; while the ordinary brazed plate heat exchanger has 4 connecting pipes (respectively responsible for two The heat medium enters and exits the heat exchanger) and is distributed on the four corners, and the invalid space is large, which interferes with the piping of the engine. [0003] Simplif...
