Description

Technical Field

[0001] The utility model relates to the technical field of spiral plate heat exchangers, in particular to a spiral plate heat exchanger with a novel channel blocking device. Background Art

[0002] The spiral plate heat exchanger is a new type of heat exchanger, which is generally made of two metal plates. The inner spiral ends of the two spaced spiral heat exchange plates are connected by a central partition. The central partition divides the gap between the two spiral heat exchange plates into two uniform spiral channels. The upper and lower ends of the spiral channels are blocked, and the two heat transfer media can flow in full countercurrent, which greatly enhances the heat exchange effect. Even if there are two small temperature difference media, they can achieve the ideal heat exchange effect, with good heat transfer efficiency and high operating stability. Multiple units can work together. For example, patent No. 202122256741.4 discloses a spiral plate heat exchanger with a new channel plugging device. By changing the original round steel plugging plate to a V-shaped strip or a flat strip, it is more suitable for a spiral channel with a larger width. There is a gap between the V-shaped strip itself and the spiral plate, which can make the welding more firm. It is more cost-effective and saves heat exchange space compared to round steel plugging, while the flat strip can further save heat exchange space and improve heat exchange efficiency.

[0003] However, the above structure cannot effectively filter and adjust the feed pipe and the discharge pipe when in use, so that it cannot effectively adjust the flow and block, which reduces its use efficiency and blocking efficiency. Therefore, we propose a spiral plate heat exchanger with a new channel blocking device. Utility Model Content
