Problems solved by technology

[0005] However, in some specific application environments, the space for placing the heat exchanger is limited, especially the space in the length direction is often limited, and the aspect ratio is difficult to meet the requirements greater than 2, such as in automotive applications, so the heat exchanger cannot be designed too long , but this will affect the realization of the target heat transfer efficiency

Embodiment Construction

[0033] Such as figure 2 The plate of the plate heat exchanger shown, the plate includes two plate planes located on the front and back sides of the plate: the first plate plane 101 (such as figure 2 shown) and the second board plane 102 (as image 3 shown). The plate includes an isolation segment that separates the plate into at least 2 regions. The isolation segment includes a first isolation segment 211, a second isolation segment 212, and a third isolation segment. The third isolation segment includes two sections of the same length adjacent to each other. The grooves that are set and recessed in opposite directions relative to the plates: the first groove 201 and the second groove 202, the first isolation section 211 and the second isolation section 212 are located at both ends of the third isolation section; the first The isolation section 211 is an extension of the first groove 201 on the plate, and the second isolation section 212 is an extension of the second groov...

Abstract

The invention relates to a sheet bar of a plate heat exchanger. The sheet bar comprises a first plate plane and a second plate plane which are located on positive and negative surfaces of the sheet bar, and separation sections which can divide the sheet bar into at least two regions; the separation sections comprise a first separation section, a second separation section and a third separation section; the third separation section comprises two slots with the same length, the slots are adjacently arranged side by side and are respectively hollowed towardsopposite directionsrelative to the sheet bar, the slots include a first slot and a second slot, and the first separation section and the third separation section are respectively located at the two ends of the second separation section; the first separation section is an extending section of the first slot on the sheet bar, and the second separation section is an extending section of the second slot on the sheet bar; and on the first sheet plane of the sheet bar, the first separation section and the first slot are hollowed, and the second separation section and the second slot are protruded; and on the second sheet plane of the sheet bar, the first separation section and the first slot are protruded, and the second separation section and the second slot are hollowed.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a plate heat exchanger and its plates. Background technique [0002] Plate heat exchanger is a compact and high-efficiency heat exchanger. It is an indispensable equipment in industrial processes. It is widely used in power, chemical, food, air conditioning, heating, machinery and other industries. It is also a new energy such as waste heat The key equipment in utilization, solar energy utilization, seawater utilization and geothermal utilization. [0003] The plate heat exchanger is stacked by a plurality of stamped and formed thin plates, which are fixed by bolts or welding. Two adjacent plates form a fluid heat exchange channel, and cold and hot fluids alternately pass through the fluid heat exchange channel for heat exchange. Only one fluid flows in one fluid heat exchange channel. The heat exchanger is provided with inlet and outlet at both ends. The material of the plate is...
