Abstract

The invention discloses a grid-plate-type V-shaped heat exchange device. The grid-plate-type V-shaped heat exchange device comprises a V-shaped heat exchange box, an air exhaust device arranged on the top part of the V-shaped heat exchange box and grid plates arranged in the V-shaped heat exchange box; the grid plates are arranged below the air exhaust device; and the grid plates are fixedly arranged on the top of the V-shaped heat exchange box. The grid plates are arranged, and the flow blocking effect of the grid plates is exerted, so that the convection speed on the top of the heat exchange device is properly lowered, and the convection speed at the bottom is increased. Furthermore, negative pressure formed under the effect of the exhaust device is uniformly distributed on the V-shaped heat exchange box; and the working efficiency at the bottom end of the V-shaped heat exchange box is improved, so that the uniformity of the convection wind speed is realized, and further the heat exchange efficiency at each part of the V-shaped heat exchange box is uniform.

Description

technical field [0001] The invention relates to the technical field of central air conditioning, in particular to a grid plate type V-shaped heat exchange device. Background technique [0002] Air-conditioning and refrigeration technology plays an indispensable role in people's daily life and commercial applications. With the consumption and shortage of energy, energy conservation and emission reduction has become an important aspect in the process of my country's economic development. Air-conditioning refrigeration technology is mainly used for room cooling in summer in daily life, and some food processing enterprises also need cold storage for food preservation. my country's air conditioners consume a lot of energy. By improving the cooling efficiency of air conditioners, the energy shortage can be effectively alleviated and the goal of energy saving and emission reduction can be achieved. The V-shaped heat exchanger of the central air conditioner is an important part of...
