Embodiment Construction

[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0040] The distribution uniformity of wind speed (air volume) on the surface of the heat exchange device has a significant impact on the heat transfer performance of the heat exchange device. Traditionally, for a substantially inverted V-shaped heat exchange device, an air guiding component is provided inside the heat exchange device so that the wind speed is evenly distributed on the heat exchange device. However, the inventors of the present application found that due to the different heat transfer coefficients of the refrigera...

Abstract

A heat exchanging device comprises a first heat exchanger, a second exchanger and an air guide member. The upper end of the first heat exchanger is connected tot the upper end of the second exchanger, the lower end of the first heat exchanger is separated from the lower end of the second heat exchanger. The lower end of the first heat exchanger is provided with a refrigerant inlet, and the lower end of the second heat exchanger is provided with a refrigerant outlet. The first heat exchanger and the second heat exchanger are formed by single planar bent heat exchangers or two independent planar heat exchanger. The air guide member is located between the first heat exchanger and the second heat exchanger and is closer to the second heat exchanger as compared with the first heat exchanger. According to a large V-shaped heat exchanger of an embodiment, the air guide member is arranged between the first heat exchanger and the second heat exchanger, distribution of air quantity can be optimized through the air guide member, the distribution of the air quantity matches with changes of heat exchanging parameters of the refrigerant, and heat exchanging capacity is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a heat exchange device. Background technique [0002] Heat exchange devices are used in a wide variety of applications, for example in air conditioners. Traditional heat exchange devices are usually flat. However, in some applications, it is necessary to bend the heat exchange device so as to divide the heat exchange device into a first heat exchanger part and a second heat exchanger part (usually called an A-shaped heat exchanger, the first The space between the heat exchanger part and the second heat exchange part is usually called the cavity of the heat exchange device). In use, the heat exchange device is placed in the box, and the wind flows upward from the bottom of the heat exchange device, and exchanges heat with the refrigerant in the heat exchange tube when passing through the first and second heat exchangers. In order to improve the heat exchange performance, ...
