Embodiment 1

[0031] Embodiment 1: as image 3 As shown, the support plate part 2 is a first support plate 3 formed by a continuous vertical I-shape, and a convex portion 31 and a concave portion 32 are formed on both sides of the first support plate 3, and the convex portion 31 is as long as the oval tube length The shapes of the inner walls on both sides of the shaft are matched, and the refrigerant medium can circulate up and down in the oval tube 1 through the concave portion 32 . The support plate is in a continuous longitudinal I-shape, which is partially in contact with the inner wall of the oval tube. Multiple gaps are formed on the support plate, and the cold medium can flow up and down in the gaps. The I-shaped support plate plays the role of support and turbulence. Allow the flowing refrigerant to stay for a long time to enhance heat exchange. The thickness of the edge of the convex part is greater than the thickness of the support plate. When the elliptical tube is heated and e...

Embodiment 2

[0032] Embodiment 2: as Figure 4 , Figure 5 As shown, the support plate part 2 is a second support plate 4 formed by a longitudinal I-shaped support plate, and the second support plate 4 is formed by a support plate body and two long side portions 41 on both sides. The long sides 41 are adapted to the shapes of the inner walls on both sides of the long axis of the elliptical tube, preventing the elliptical tube from deforming. The thickness of the long side part 41 is greater than the thickness of the longitudinal I-shaped support plate 4, which matches the shape of the elliptical tube. When the elliptical tube is heated and expanded, the contact area is increased and the supporting effect is improved. In addition, the upper and / or lower parts of the second support plate 4 are provided with serrations 42 to further enhance the supporting effect and prevent the oval tube from deforming.

Embodiment 3

[0033] Embodiment 3: as Image 6 , Figure 7 As shown, the support plate part 2 is a third support plate 5 formed by a continuous horizontal I-shape, and the third support plate 5 is sequentially arranged on the two side frame parts 52 by a plurality of single pillars 51, and the two side frame parts 52 are adapted to the shapes of the inner walls on both sides of the long axis of the elliptical tube respectively, and the refrigerant medium can circulate up and down in the elliptical tube 1 through the gap between the pillars. The frame part is in full contact with the elliptical tube wall, and the supporting effect remains unchanged. Refrigerant can flow up and down through the gap between the pillars, and the I-shaped support plate plays the role of turbulence and enhances heat exchange. The thickness of the frame part 52 is greater than the thickness of a single support 51, which conforms to the shape of the elliptical tube. When the elliptical tube is heated and expanded...

Abstract

The invention discloses a heat exchanger which comprises an inlet header, an outlet header, fins arranged between the inlet header and the outlet header in a densely stacked mode and an oval pipe penetrating through the fins and enabling the inlet header to be communicated with the outlet header. A supporting board component is arranged in the oval pipe in the long axis direction of an oval and is in clearance fit with the inner wall of the oval pipe. The supporting board component is of a rectangular board shape and can be formed in three shapes, namely a first supporting board formed by continuous longitudinal I shapes or a second supporting board formed by longitudinal I-shaped supporting board bodies or a third supporting board formed by continuous transverse I shapes. The heat exchanger has the advantages that the inner wall of the oval pipe is supported by the supporting board component, so that the long axis is not shrunk and the oval pipe is prevented from changing to a circular pipe. A cold medium flow channel is formed in the supporting board component, so that the function of turbulent flow is achieved and the heat exchanging effect is enhanced.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a heat exchanger in refrigeration and air conditioning. Background technique [0002] Generally speaking, in refrigeration equipment such as air conditioners, compressors, condensers, expansion valves, and evaporators form a refrigeration cycle system, and heat exchange devices such as condensers and evaporators are collectively referred to as heat exchangers. In the heat exchanger, the refrigerant changes from liquid to gas or from gas to liquid to exchange heat with the surrounding air, that is, to absorb heat or release heat, so as to achieve the cooling effect. The heat dissipation effect of the heat exchange device will directly affect the refrigeration energy efficiency of the entire refrigeration equipment. [0003] The traditional heat exchange device uses coiled tubes and heat dissipation fins set on the coils to exchange the heat of the medium in the tube with the outsi...
