A folded, elongated tube (28) is provided for use in a heat exchanger (10, 11). The tube (28) has a flattened cross section with a minor dimension (d) and a major dimension (D). The tube (28) includes a pair of parallel tube runs (36), and a folded section (40) connecting the pair of tube runs (36). The major dimensions (D) of the tube runs (36) lie in a common plane. The folded section (40) includes a U-shaped bend (42), a first twist (44), and a second twist (46). The U-shaped bend (42) includes a straight section (48) extending between two curved sections (50, 52), and has its major dimension (D) extending substantially transverse to the major dimension (D) of the tube runs (36). The first twist (44) connects one of the tube runs (36) to the curved section (50), and the second twist (46) connects the other tube run (36) to the other curved section (52) of the U-shaped bend (42).

A heat exchanger includes a plurality of tubes, a pair of header pipes, partition walls, an inlet connector block and an outlet connector block. The plurality of tubes have one ends connected to one header pipe and other ends connected to the other header pipe. The header pipe internally has a pipe-inside flow-through bore. The partition wall is internally formed in each header pipe to divide the pipe-inside flow-through bore into two regions. Each header pipe has a block connector bore opening at an outer side wall opposing to an area to which the tubes are connected and opening to the pipe-inside flow-though bore by cutting out a portion of the partition wall. The inlet connector block is connected to the block connector bore of one header pipe to admit coolant to flow in. The outlet connector block is connected to the block connector bore of the other header pipe to permit coolant to flow out.
摘要:
An evaporator for conducting a heat exchanger between a refrigerant and ambient air including a plurality of refrigerant tubes, at least two header tanks in fluid communication with the plurality of refrigerant tubes and at least one of the heater tanks having a plurality of serrations through which refrigerant flows into each of the plurality of refrigerant tubes and a plurality of fins dispersed between each of the plurality of refrigerant tubes.
摘要:
A heat exchanger apparatus includes a first and second coolant tanks spaced apart from each other, a plurality of heat exchanging tubes extending between the tanks for enabling coolant to flow from the first coolant tank to the second coolant tank and to be cooled in said tubes, and a coolant supply/return tube for enabling coolant to flow from the second coolant tank to the first coolant tank. The supply/return tube has a substantially circular cross-section. The supply/return tube has opposite end portions inserted into complementary openings in the inlet coolant reservoir and the first tank. In order to provide the proper, predetermined orientation of the supply/return tube in the heat exchanger apparatus, the supply/return tube has opposite locating members each adjacent to the end portions of the supply/return tube, so that a small, predetermined length of the end portions of the supply/return tube protrudes inside the supply/return tube.
摘要:
Heat exchanger core comprising flat plate fluid U flows tubes stacked on one another and operatively connected to one another by discrete fluid supply and suction lines. These lines extending through side-by-side tank portions of the tubes to improve structural integrity of the core and respectively have fluid feed and exhaust openings communicating with the tanks and sized to provide even distribution of the heat exchanger fluid to the tubes. With the supply and suction lines, evenly distributing the heat exchanger fluid, tank size and capacity is optimized and the requirement for large capacity deep draw tanks of prior constructions is eliminated.
摘要:
An evaporator includes a plurality of laminated tubes, each of which is provided therein with a refrigerant passage, an inlet header chamber which is in communication with one end of the refrigerant passage, and an outlet header chamber which is in communication with the other end of the refrigerant passage. The inlet header chamber is located above the refrigerant passage. The inlet header chamber is partitioned by a partition wall into an inner header chamber and an outer header chamber which is disposed around the inner header chamber and which is in communication with the refrigerant passage. The inner header chambers of the adjacent tubes are in communication with each other. An assembly of the inner header chambers forms a header inlet tank chamber. The partition wall is provided with refrigerant holes located above a lowermost point a of the inner header chamber and at different levels.
摘要:
A header construction intended for use in a heat exchanger (36) employed in a relatively high pressure application includes an array of generally parallel tube runs (84) with fins (82) extending between adjacent ones of the tube runs. At least one relatively flat header plate (86) has a plurality of tube slots (88) for receiving ends (90) of the tubes (84) and a tank (94) is mounted to and sealed to the header plate (86). Peripheral flanges (112) are located about tube slots (86) in the headers and a header reinforcing plate (114) is bonded to the header plate (86) oppositely of the tank (94). Stiffening beads in the form of flanges (120) are located on the header reinforcing plate (114) between openings (118) therein through which the tubes (84) pass and extend away from the header plate (86).
摘要:
A heat exchanger for a CO2 refrigerant includes at least three rows of tube groups including a plurality of tubes having an independent refrigerant path, first and second header pipes including a header where a plurality of tube insertion holes into which the tubes are inserted are formed and a tank having partition walls formed along a direction of the flow of a refrigerant, wherein a plurality of return holes are formed in the partition walls, end caps sealing both end portions of the firs and second header pipes, a coupling reinforcement portion installed at least one of the first and second header pipes and reinforcing a coupling force of the header and the tank, a refrigerant inlet pipe connected to the first or second header pipe through which the refrigerant enters, and a refrigerant outlet pipe connected to the first or second header pipe through which the refrigerant is exhausted. The refrigerant entering through the refrigerant inlet pipe is made to flow in a direction adverse to a direction in which air flows.
