板式换热器结构图.jpg

The plate heat exchanger is formed by pressing a number of pressed corrugated metal plates at a certain interval, sealed around by gaskets, and compressed by a frame and tightening bolt groups. The four corner holes of the plates and gaskets form a fluid separation. The piping and the collection pipe can also reasonably freely conduct cold diversion and distribution of hot and cold fluids, and perform heat transfer through the plates to achieve the purpose of heat exchange. The basic components of the plate heat exchanger (see figure), where the plate is a heat transfer element, which determines the heat rate, resistance loss, bearing capacity, applicable fluid and applicable life of the plate heat exchanger; the gasket determines the plate heat exchanger Capacity, applicable fluids, and maintenance intervals.

Features:

It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, and long service life. 3-5 倍,占地面积为 管式换热器的三分之一,热回收率可高达 90% 以上。 Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube-type heat exchanger , the floor area is one-third that of the tube-type heat exchanger, and the heat recovery rate can be as high as 90% or more.

RF 系列) Asymmetric series ( RF series)

Characteristics of asymmetric flow channel plate heat exchanger

NTU )或热长度( θ )是不相同的。 Generally, the number of heat transfer units ( NTU ) or heat length ( θ ) of the two fluids for heat exchange are different. 或( θ )值取决于流体的热容量,(即流量与定压比热容之积或温差)同一流体取决于流量大小。 The NTU or ( θ ) value depends on the heat capacity of the fluid, (ie, the product or temperature difference between the flow rate and the constant pressure specific heat capacity). The same fluid depends on the flow rate. NTU 或( θ )值应与相应流体“匹配”。 In order to achieve economical and effective heat transfer without causing the heat exchanger to be too large, the NTU or ( θ ) value of the hot and cold flow channels on both sides should "match" the corresponding fluid.

The characteristics of the flow channels on the cold and hot sides of a conventional plate heat exchanger are exactly the same (symmetric flow channels), and it is difficult to achieve "precise matching" even with the "hot mixing" design technology. 0.7-1.4 ,往往总有一侧的压力降无法充分利用,导致换热器传热性能较差,换热面积无畏浪费。 The range of flow ratio of the two fluids passing through the plate heat exchanger is only 0.7-1.4 . Often, the pressure drop on one side cannot be fully utilized, resulting in poor heat transfer performance of the heat exchanger and fearless waste of heat exchange area.

RF 系列产品,采用同一板片组成不同几何尺寸和形状的流道(非对称流道)较完美的解决了“精准匹配”的问题。 The RF series products developed by our company use the same plate to form flow channels (asymmetric flow channels) of different geometric sizes and shapes, which perfectly solves the problem of "precise matching". Or liquid and gas containing solid particles can guarantee operation.

RF 系列产品具有以下特点: Compared with conventional plate heat exchangers, the RF series products have the following characteristics:

1.          The applicable two fluid ratio (or heat capacity ratio, temperature difference ratio) has a wide range. 1.5-3.0 ,设计压力可达 2.5MPa 以上。 It can reach 1.5-3.0 , and the design pressure can reach more than 2.5MPa .

2.          30% 以上。 Under the full use of the allowable pressure drop on both sides, the heat transfer coefficient can be increased, and the heat transfer area can be saved by more than 30% .

3.          50% 左右。 Under the conditions of meeting the same thermal load, the pressure drop can be reduced by about 50% .

4.          Normally, the single plate process can be used to deal with the multi-process conditions of the conventional plate heat exchanger, so that the connection pipe is located on the side of the fixed clamping plate, which is convenient to install and maintain.

5.          The cross-sectional area of one side of the flow channel is twice that of the other side, which is suitable for the treatment of fluids that are refrigerated or have small size particles, fibers and other impurities.
