A heat exchanger 100 according to an embodiment of the present invention is described with reference to fig. 1 to 5, and the heat exchanger 100 may be used in a heating apparatus such as a water heater, for example, a heat pump water heater, and the heat exchanger 100 is described below with a specific example.
Referring to fig. 1 and 2, a heat exchanger 100 according to an embodiment of the present invention includes a flow dividing pipe 110, a flow dividing pipe 120, and a plurality of heat exchanging pipes 130, wherein the flow dividing pipe 110 and the flow dividing pipe 120 are spaced apart from each other, one end of each heat exchanging pipe 130 is connected to the flow dividing pipe 110, the other end of each heat exchanging pipe 130 is connected to the flow dividing pipe 120, and the plurality of heat exchanging pipes 130 are spaced apart from each other and disposed between the flow dividing pipe 110 and the flow dividing pipe 120, so that the heat exchanging pipes 130 communicate the flow dividing pipe 110 and the flow dividing pipe 120.
The flow dividing pipe 110 is provided with an inlet 111, the collecting pipe 120 is provided with an outlet 121, and when the heat exchanger works, compressed high-temperature and high-pressure refrigerant enters the flow dividing pipe 110 through the inlet 111, then flows into each heat exchange pipe 130 in a flow dividing manner, enters the collecting pipe 120 after heat exchange in the heat exchange pipe 130, and then flows out of the outlet 121; the heat exchange tube 130 can be in direct contact with the heated body, and the carried heat can be transferred to the heated body through the heat exchange tube 130 due to the higher temperature of the refrigerant, so that the heating effect is achieved. Taking the heat pump water heater as an example, the heat exchange tube 130 is tightly attached to the water tank liner 300 of the heat pump water heater, so that the heat generated by the heat exchange tube 130 can heat the water in the water tank liner 300, thereby realizing the heat exchange process of the refrigerant to the water.
Referring to fig. 1, the dividing pipe 110 and the collecting pipe 120 extend in a vertical direction, the inlet 111 is disposed at the bottom end of the dividing pipe 110, the outlet 121 is disposed at the bottom end of the collecting pipe 120, the plurality of heat exchange pipes 130 are arranged at intervals in the vertical direction and are arranged in parallel, and a certain gap 140 is formed between adjacent heat exchange pipes 130 to form a parallel flow heat exchanger.
Referring to fig. 1, the heat exchange tube 130 of the embodiment has a flat tube structure, the width of the heat exchange tube 130 is greater than the thickness of the heat exchange tube 130, as shown in fig. 1, the length of the heat exchange tube 130 is a dimension in a horizontal direction, the width of the heat exchange tube 130 is a dimension in a vertical direction, and the thickness of the heat exchange tube 130 is a dimension perpendicular to the horizontal and vertical directions.
The heat exchange tubes 130 have two side surfaces along the thickness direction, the two side surfaces are respectively a first heat exchange surface 132 and a second heat exchange surface 133, the first heat exchange surfaces 132 of all the heat exchange tubes 130 face to the same side, the first heat exchange surfaces 132 are used for being attached to the water tank liner 300, and heat of a refrigerant can be transferred to the water tank liner 300 through the first heat exchange surfaces 132, so that a heating effect is achieved.
It can be understood that the larger the contact area of the heat exchange pipe 130 with the tank liner 300, the more efficient the heat transfer. As shown in fig. 1, the heat exchange tube 130 is flat, and the areas of the first heat exchange surface 132 and the second heat exchange surface 133 are both larger than the area of the side surface of the heat exchange tube 130 along the width direction, so that the contact area between the heat exchange tube 130 and the water tank liner 300 is larger, which is beneficial to improving the heat exchange efficiency.
Because the gap 140 is formed between the adjacent heat exchange tubes 130, and the heat exchange tubes 130 are not in contact with the tank liner 300 at the position of the gap 140, in the embodiment, the heat conducting member 200 is added to the heat exchanger 100, and the heat conducting member 200 is made of a high heat conducting material, such as stainless steel, copper, aluminum alloy, and the like, so that the heat conducting member 200 has a better heat transfer performance, the heat of the heat exchange tubes 130 can be transferred to the position of the gap 140 through the heat conducting member 200, the heat generated by the heat exchanger 100 can be fully utilized, and the heat exchange efficiency is further improved.
Specifically, referring to fig. 1 and 2, the heat conductive member 200 is coupled to the heat exchange pipe 130, and the heat conductive member 200 covers the gap 140.

That is to say, when first heat transfer surface 132 and water tank inner bag 300 outer wall are closely laminated, first heat conduction surface 211 can laminate simultaneously on water tank inner bag 300's outer wall, the heat of heat exchange tube 130 transmits to water tank inner bag 300 through first heat transfer surface 132, still can transmit the heat to heat-conducting piece 200, locate to transmit the heat to water tank inner bag 300 through first heat conduction surface 211 in clearance 140, first heat transfer surface 132 and first heat conduction surface 211 all play the effect of transmission heat, thereby increase the area of heat exchange tube 130 and water tank inner bag 300 contact, heat exchange efficiency is higher, it is more efficient to heat.

Because the heat of the heat exchange tube 130 can be transferred outwards through the first heat exchange surface 132 and the second heat exchange surface 133, and the second heat conduction surface 221 is in contact with the second heat exchange surface 133, the heat generated by the second heat exchange surface 133 can be transferred to the first heat conduction surface 211 through the second heat conduction surface 221, so that the effective heat transfer effect is achieved, and the heat exchange efficiency is improved.
It should be noted that the first heat conduction surface 211 and the second heat conduction surface 221 can be understood as two surfaces at different positions on the heat conduction member 200, as shown in fig. 2, the first heat conduction surface 211 and the first heat exchange surface 132 face to the same side and are located on the same plane, and the second heat conduction surface 221 covers the second heat exchange surface 133, so that the second heat conduction surface 221 and the second heat exchange surface 133 can be tightly attached to each other, which is beneficial to improving the heat conductivity.
