Abstract
The invention relates to an asymmetrical flat tube for a heat exchanger passage. The asymmetrical flat tube for the heat exchanger passage comprises a flat tube body. Two hot fluid passage holes with the same size are arranged in the flat tube body. The two sides of the middle part of each hot fluid passage hole are in parallel with each other. The two ends of each hot fluid passage hole are semicircular. A direct connecting notch is arranged on one side of the flat tube body. An arc-shaped transitional connecting notch is arranged on the other side of the flat tube body. The lower surface of the flat tube body is a flat installation surface. A plurality of radiating ribs are evenly arranged at the upper surface of the flat tube body. The radiating ribs are regularly triangular. The distance of every two adjacent radiating ribs is equal to the length of sides of the radiating ribs. The asymmetrical flat tube for the heat exchanger passage provided by the invention has the beneficial effects that the direct connecting notch on one side is connected with one fixing piece, the arc-shaped transitional connecting notch on the other side is butted with another fixing piece, the radiating area is increased through the radiating ribs on the upper surface and the goal of accelerating heat transfer is achieved.
Description
Technical field
The present invention relates to a kind of heat exchanger passages and use asymmetric flat tube.
Background technology
The heat exchanger channels of existing heat exchanger in order to improve heat-transfer rate, adopts the material of good heat conductivity, but generally speaking, heat transfer efficiency promotes 20%, and the cost of manufacturing equipment will promote 100%.A lot of enterprises that use heat exchanger, in order to seek heat exchanger more efficiently, the procurement price of having to is the high-grade radiator of costliness very, but in fact the lifting of its radiating effect is not directly proportional with price.So how a kind of heat exchanger passages structure of good heat conductivity is provided is the technical problem that present heat exchanger field faces jointly.
Summary of the invention
The objective of the invention is to overcome above-mentioned prior art problems, provide a kind of heat exchanger passages to use asymmetric flat tube.
The objective of the invention is to realize through following technical scheme:
A kind of heat exchanger passages is used asymmetric flat tube, comprises the flat tube body, and the inside of flat tube body is provided with two zone of heat liberation holes that size is identical; The middle part in said zone of heat liberation hole is a parallel channels, and two ends are semi-circular channel, is provided with direct-connected breach in a side of said flat tube body; Opposite side is provided with arc-shaped transition and connects breach; The bottom of flat tube body is made as the Plane Installation face, and the flat tube upper part of body evenly is provided with several heat radiation fins, and said heat radiation fin is triangular in shape;
Further, said heat radiation fin is an equilateral triangle, and the distances of adjacent two heat radiations between the fins equal the to dispel the heat length of side of fin.
Heat exchanger passages of the present invention is used asymmetric flat tube; The direct-connected breach of one side is connected with fixture; The house type transition of opposite side connects breach docks with another fixture, and the heat radiation fin that has through upper face increases area of dissipation, and then reaches the purpose of accelerating heat transfer effect.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structure chart of heat exchanger passages according to the invention with asymmetric flat tube.
The specific embodiment
As shown in Figure 1, the described heat exchanger passages of the embodiment of the invention is used asymmetric flat tube, comprises flat tube body 1; The inside of flat tube body 1 is provided with two zone of heat liberation holes 2 that size is identical; The middle part in said zone of heat liberation hole 2 is a parallel channels, and two ends are semi-circular channel, is provided with direct-connected breach 3 in a side of said flat tube body 1; Opposite side is provided with arc-shaped transition and connects breach 4; The bottom of flat tube body 1 is made as the Plane Installation face, and the flat tube upper part of body evenly is provided with several heat radiation fins 5, and said heat radiation fin 5 is triangular in shape; Said heat radiation fin 5 is an equilateral triangle, and the distances of adjacent two heat radiations between the fins 5 equal the to dispel the heat length of side of fin 5.
Heat exchanger passages of the present invention is used asymmetric flat tube; The direct-connected breach of one side is connected with fixture; The house type transition of opposite side connects breach docks with another fixture, and the heat radiation fin that has through upper face increases area of dissipation, and then reaches the purpose of accelerating heat transfer effect.
