Problems solved by technology
However, under the current technical conditions, due to the large area of the cover plate, no reinforcing ribs can be added to the air outlet of the cover plate and the heat exchange core, so under the elastic force of the sealing strip, the air outlet of the cover plate often appears convex Deformation and gaps are formed, so that air leakage occurs in the middle of the cover plate, and the air from the air outlet enters the inner circulation cavity from the gap and then enters the heat exchange core, thus affecting the working efficiency of the heat exchange unit
Moreover, in rainy days, rainwater can enter the external circulation cavity of the unit from the air inlet of the external circulation. Under the action of the external circulation fan, the rainwater may be blown into the internal modules of the cabinet through the gap formed by the protruding cover plate. For equipment, this is absolutely not allowed, and does not meet the requirements for high reliability of the heat exchange unit
At the same time, the raised air outlet also affects the appearance

The invention relates to the field of heat exchange units, and provides a heat exchange unit with an anti-deformation cover plate, including a box body, an internal circulation fan, an electric heater, a heat exchange core, an external circulation fan, a cover plate, a controller, a transformer and an AC unit. In the DC converter, the space surrounding the internal circulation fan composed of the box body, the cover plate and the heat exchange core is called the internal circulation cavity, and the space surrounding the external circulation fan is called the external circulation cavity. The rectangular air outlet of the cover plate The two long sides are turned inward respectively. The invention effectively solves the sealing problem of the air outlet of the heat exchange unit by designing the long side of the air outlet into a flanging structure, improves the working efficiency of the heat exchange unit, and makes the heat exchange unit more beautiful.
Description
technical field [0001] The invention relates to the field of heat exchange units, in particular to a heat exchange unit with a deformation-resistant cover plate. Background technique [0002] With the development of communication technology, communication cabinets for signal transmission and reception have spread all over the world. The calorific value of the communication cabinet is usually in the range of 500W to 4500W. In order to protect the temperature-sensitive components in the cabinet, reduce thermal stress, improve the effective life, and ensure that the electronic equipment works in the best performance state, it is usually necessary to control the temperature in the cabinet. Adjustment, within this range of cooling capacity, the cost of using air conditioners is high and the reliability is low, while the use of heat exchangers is low in cost, high in reliability, and environmentally friendly and energy-saving. There are many communication cabinet sites, and most ...
