Problems solved by technology

At present, the fins of heat exchangers on the market are mostly rectangular, and the bottom surface is located on the same horizontal line. The condensed water is easy to accumulate at the bottom due to tension and is not easy to fall, thus affecting the heat exchange effect.
Moreover, water dripping will easily affect the working environment of the instrument. If there is a power supply nearby, it will easily cause danger.
Moreover, the top surface of the fins of the heat exchanger is a horizontal structure, which is easy to accumulate dust, which also affects the heat exchange effect

Embodiment Construction

[0011] Such as figure 1 The heat exchanger includes 10 vertically arranged fins 1, the upper end surface 2 of the fin 1 is in the shape of an upright right triangle, which can reduce dust accumulation, and the lower bottom surface 3 is in the shape of an inverted right triangle , can make the condensed water droplets flow along the part of the hypotenuse of the triangle to the bottom side in time, and the lower bottom surface 3 is provided with a water receiving tank 4 below the right-angled side of the inverted right-angled triangle shape, but the condensed water drips into the water receiving tank, effectively Prevent the condensed water from condensing at the bottom of the fins, which will not easily drip and affect the heat exchange effect. The condensed water will drip into the water receiving tank, which can ensure the sanitation and safety of the working environment and effectively avoid accidents.

[0012] The present invention has been described in detail above, but t...

Abstract

A heat exchanger comprises at least five vertically-arranged fins and is characterized in that the upper end surfaces of the fins are in the shape of upright triangle, the bottom surfaces of the fins are in the shape of inverted right triangle, and a water collecting tank is arranged under the right-angle side of the inverted right triangle of every bottom surface. The heat exchanger is safe and reliable in structure, high in heat transfer efficiency, easy to manufacture, install and operate and less in maintenance as well as reduces dust accumulation.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a commonly used heat exchanger in the chemical industry. Background technique [0002] A heat exchanger is a heat exchange device that transfers part of the heat of the hot fluid to the cold fluid so that the temperature of the fluid reaches the index specified in the process, also known as a heat exchanger. Most of the heat exchangers used as evaporators are equipped with multiple vertical heat exchanger fins. When the surface temperature of the fins is lower than the air temperature, the surface of the fins will condense into water. At this time, the fins placed vertically The fins are beneficial for water droplets to fall vertically along the fins under the action of gravity. At present, the fins of heat exchangers on the market are mostly rectangular, and the bottom surface is located on the same horizontal line. The condensed water is easy to accumulate at the bottom due to tension and i...
