板式换热器由于构造上的特殊性，其维修、清洗和部件更换等要求有较高的专门技术水平，否则不仅达不到预期效果，反而会发生设备漏水、变形甚至损坏等严重故障。因此大多数板式换热器的用户，都是请原设备厂家或专业公司进行维修和清洗的。
Plate heat exchanger due to the special structure, the maintenance, cleaning and replacement of parts such as high specialized technical level, otherwise not only fail to expected results, but will be leaking equipment, deformation and damage and other serious problems. Therefore most heat exchanger users are original equipment manufacturers or Professional Company please for maintenance and cleaning.
我们通过几年的实践摸索，逐渐掌握了板式换热器的维修、清洗和部件更换的方法。自行对冷却循环水用的板式热交换器进行清洗和维护，省去了昂贵的清洗费用，并取得了非常好的效果。另一方面，换热片结垢之后，其热阻明显增加，此时的冷媒（或热媒）流体不容易把冷量（或热量）传输到被交换的工作流体侧，此时，即使是通人换热器的冷媒（或热媒）流量不变，其换热效率将明显变差。
We grope through several years of practice, gradually mastered the method of maintenance, cleaning and replacement of the components of plate heat exchanger. The plate heat exchanger for cooling circulating water for cleaning and maintenance, saves the cleaning cost expensive, and achieved very good results. On the other hand, heat exchange fin fouling, the resistance was increased, at this time of the refrigerant (HTM) fluid is not easy to cold (or heat) transfer to the exchange is the working fluid side. At this time, even if is Walter heat exchanger cooling medium (HTM) constant flow and the heat transfer efficiency will be significantly worse.
In this situation, if the process is still required to maintain the original exchange efficiency unchanged, it is necessary to increase the inlet pressure at the same time increase the flow into the heat exchanger, which resulted in a double increase in energy consumption.
