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 Figure 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 expande...

Abstract

The invention discloses a heat exchanger, comprising: an inlet header, an outlet header arranged closely stacked between the inlet header and the outlet header, and an ellipse penetrating through the flap to connect the inlet header and the outlet header. A tube, and a support plate part is provided along the long axis of the ellipse inside the ellipse tube, and the support plate part is in clearance fit with the inner wall of the ellipse tube. The support plate part is in the shape of a rectangular plate, including three types of plates, that is, the first support plate formed by continuous vertical I-shaped support plates, the second support plate formed by longitudinal I-shaped support plates or the continuous horizontal I-shaped support plate the third board. The beneficial effects of the present invention are: the present invention supports the inner wall of the elliptical tube through the support plate to ensure that the long axis does not shrink, thereby preventing the elliptical tube from becoming a round tube. The cooling medium channel provided on the support plate plays the role of turbulence and enhances the heat exchange effect.

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...
