Definitions

  • the present disclosure generally relates to a heat exchanger according to the preamble of claim 1, more particularly, to a heat exchanger having a substantially inverted V-shape.
  • Such a heat exchanger is known from US 2005/0241812 A1 .
  • the heat exchanger is widely used in various fields, such as air conditioners.
  • a conventional heat exchanger generally has a flat rectangular shape of so called parallel flow type.
  • the heat exchanger should be bent into a substantially inverted V-shape, thus the heat exchanger is divided into first and second heat exchanger portions which are located at two sides (i.e., the refrigerant inflow side and the refrigerant outflow side) of the bending portion respectively.
  • each fin is divided into a first fin portion in the first heat exchanger portion and a second fin portion in the second heat exchanger portion, and the first and second fin portions have identical structure and design.
  • the inlet air flows upward from a lower side of the heat exchanger, exchanges heat with the refrigerant in the tubes when passing through the heat exchanger, and then flows out from an upper side of the heat exchanger as the outlet air.
  • the temperature of the refrigerant is changed along the flow direction in the heat exchanger. For example, if the heat exchanger is used as an evaporator, the temperature of the refrigerant increases along the flow direction. Since the structure of the first and second fin portions at two sides of the bending portion are identical and the temperatures of the refrigerant at two sides of the bending portion are different, the temperatures of the outlet air at two sides of the bending portion are different.
  • the capacity on the refrigerant inflow side is higher than that on the refrigerant outflow side, so that the temperature of the outlet air on the refrigerant outflow side is higher than that of the outlet air on the refrigerant inflow side.
  • the difference of the temperature of the outlet air at two sides of the bending portion may affect the heat exchange performance.
  • the difference of the temperature of the outlet air on the two sides of the bending portion may affect the comfortableness.
  • the heat exchanger is used as a condenser
  • the temperatures of the outlet air at two sides of the bending portion are also different, thus affecting the heat exchange performance.
  • WO 2005/075918 A1 shows a partially structured heat exchanger laminae.
  • the heat exchanger has a second header connected to an outlet line and a plurality of tubes spaced apart from each other and each connected to the second header in further communication therewith. Furthermore, a plurality of fins are disclosed each disposed between adjacent tubes.
  • the laminae have a first portion in which they are not smooth, preferably corrugated, and a portion, in which they are smooth. However, there is nothing disclosed about a bent portion between these two portions of the laminae. As far as can be seen in the drawing and in the description, the bent portions of the tubes are located within either the corrugated portion of the laminae or the smooth portions of the laminae.
  • US 2004/0168456 A1 discloses an evaporator for medium temperature refrigerated merchandiser having a tube which is guided in a serpentine-like form. Fins are disposed in contact with the tubes. The density of the fin in an air entry side of the heat exchanger is larger than the density at an air outlet side. This is achieved by arranging additional short fins at the entry side.
  • the present disclosure is directed to a heat exchanger bent into a substantially inverted V-shape, in which the capacities at two sides of a bending portion are substantially identical, thus improving the heat exchange performance.
  • the capacity of the second heat exchanger portion may be substantially identical with that of the first heat exchanger portion, so that the temperature of the outlet air passing through the second heat exchanger portion may be substantially identical with that of the outlet air passing through the first heat exchanger portion, thus improving the heat exchange performance.
  • the heat exchanger is used in the air conditioner, the comfortableness is improved.
  • each fin is divided into a first fin portion in the first heat exchanger portion and a second fin portion in the second heat exchanger portion, and a heat transfer coefficient of the second fin portions is greater than that of the first fin portions.
  • each of the first and second fin portions is formed with louvers, in which a louver angle of the louvers in each second fin portion is greater than that of the louvers in each first fin portion and/or.
  • each of the first and second fin portions is formed with louvers, in which a louver length of the louvers in each second fin portion is greater than that of the louvers in each first fin portion.
  • each of the first and second fin portions has a substantially corrugated shape, and a fin pitch of each second fin portion is smaller than that of each first fin portion.
  • the heat transfer coefficient of the first fin portion may be smaller than that of the second fin portion, so that the temperature of the outlet air passing through the second heat exchanger portion may be substantially identical with that of the outlet air passing through the first heat exchanger portion, thus improving the heat exchange performance and decreasing the cost.
  • the heat exchanger further comprises a third header and a fourth header, wherein the first header and the third header are connected and communicated via the first tube portions, and the second header and the fourth header are connected and communicated via the second tube portions; in which the third header and the fourth header are connected and communicated via a connection pipe; and in which the bent portion is formed by bending the connection pipe.
  • the heat exchanger is formed by bending a single heat exchanger of parallel flow type.
  • no fins are disposed in the bent portion.
  • the heat exchanger is bent into an invented V-shape
  • the bent heat exchanger may be formed by bending a single complete parallel flow type heat exchanger such as a flat plate heat exchanger in which both tubes and fins are bent. Further, in a middle portion of the flat plate heat exchanger, no fins are disposed in the middle portion to be bent, that is, only tubes are bent. Therefore, the heat exchanger is easy to bend and the bending of the heat exchanger will not disadvantageously affect the heat exchange performance.
  • the bent heat exchanger may be formed by two separate flat plate heat exchangers, in which the two flat plate heat exchanger are connected in series for example by a connection pipe communicating the outlet header of one flat plate heat exchanger with the inlet header of the other flat plate heat exchanger, and the two flat plate heat exchanger form an angle larger than zero and less than 180 degree for example by bending the connection pipe. Therefore, the bent heat exchanger is easier to manufacture and high in applicability.
  • phraseology and terminology used herein with reference to device or element orientation are only used to simplify description of the present invention, and do not alone indicate or imply that the device or element referred to must have or operated in a particular orientation.
  • terms such as “first” and “second” are used herein for purposes of description and are not intended to indicate or imply relative importance or significance.
  • connection and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings.
  • the heat exchanger is used as an evaporator in an air conditioner. It will be appreciated that the heat exchanger according to embodiments of the present disclosure is not limited to this, for example, the heat exchanger may be also used as a condenser, and may be also used in other equipments such as a refrigerator.
  • the heat exchanger comprises a first header 1, a second header 2, a plurality of tubes 3 such as flat tubes, and a plurality of fins 4.
  • the tubes 3 are arranged and spaced apart from each other in a direction parallel to the axial direction of the first and second headers 1 and 2. Two ends of each tube 3 are connected to the first header 1 and second header 2 respectively in fluid communication with the first header 1 and second header 2.
  • the plurality of fins 4 are each disposed between adjacent tubes 3, and the fins 4 and the tubes 3 form the core of the heat exchanger.
  • the heat exchanger may be used as the evaporator in an air conditioner, for example, the first header 1 is used as an inlet header, the second header 2 is used as an outlet header, the refrigerant flows from the first header 1 to the second header 2 in the tubes 3, and the temperature of the refrigerant is increased from the first header 1 to the second header 2 in the tubes 3.
  • the heat exchanger is formed by bending a single heat exchanger of parallel flow type between the inlet header 1 and the outlet header 2 into a substantially inverted V-shape.
  • the heat exchanger has a bent portion between the first header 1 and second header 2.
  • the refrigerant flows from the first header 1 to the second header 2, the temperature of the refrigerant increases from the first header 1 to the second header 2 in the tubes 3, and a length direction of a folding line of the bent portion is consistent with a width direction (the direction perpendicular to the paper in Fig.1 ) of the core of the heat exchanger.
  • the heat exchanger is divided by the bent portion into first heat exchanger portion 100 and second heat exchanger portion 200 which are located at the right side and the left side in Fig. 1 (a refrigerant inflow side and a refrigerant outflow side, i.e.,) of the bent portion respectively.
  • each fin 4 is divided into a first fin portion 4a in the first heat exchanger portion 100 and a second fin portion 4b in the second heat exchanger portion 200
  • each tube 3 is divided into a first tube portion 3a in the first heat exchanger portion 100 and a second tube portion 3b in the second heat exchanger portion 200.
  • the second fin portion 4b is disposed between adjacent second tube portions 3b and the first fin portion 4a is disposed between adjacent first tube portions 3a.
  • a heat transfer coefficient of the second heat exchanger portion 200 is greater than that of the first heat exchanger portion 100. Therefore, the capacity of the second heat exchanger portion 200 is substantially identical with that of the first heat exchanger portion 100, so that the temperature t2 of the outlet air A2 at the left side in Fig. 1 may be substantially identical with the temperature t1 of the outlet air A1 at the right side in Fig 1 , thus improving the heat exchange performance, and thereby, for example, improving the comfortableness of an air conditioner.
  • the inlet air A having a temperature of t flows upward from a lower side of the heat exchanger, exchanges heat with the refrigerants in the first tube portion 3a and the second tube portion 3b respectively when passing through the first heat exchanger portion 100 and the second heat exchanger portion 200, and then flows out from the upper sides of the first heat exchanger portion 100 and the second heat exchanger portion 200, in which the outlet air A1 flowing out from the upper side of the first heat exchanger portion 100 has a temperature of t1 and the outlet air A2 flowing out from the upper side of the second heat exchanger portion 200 has a temperature of t2.
  • the temperature t2 of the outlet air A2 may be substantially identical with the temperature t1 of the right outlet air A1 if Q1 is equal to Q2.
  • the temperature of the refrigerant increases from the right side of the heat exchanger to the left side thereof, as shown in Fig. 1 , the refrigerant flows in a direction denoted by an arrow B1 in the first heat exchanger portion 100 and flows in a direction denoted by an arrow B2 in the second heat exchanger portion 200. Therefore, if the structure and the design of the first fin portion 4a are identical with those of the second fin portion 4b, Q1 will be greater than Q2.
  • the heat transfer coefficient of the second heat exchanger portion 200 is increased, thus increasing the capacity of the second heat exchanger portion 200, so that Q1 may be substantially equal to Q2. Therefore, the temperature t2 of the outlet air A2 may be identical with the temperature t1 of the outlet air A1, thus improving the heat exchange performance.
