  • Patent number: 10625564
    Abstract: The present invention relates to an outdoor heat exchanger, and more particularly, to a down flow type outdoor heat exchanger having channels of at least three paths in a heat pump system for vehicles, in which a flux distribution means protruded in a height direction is further formed in a lower tank in which the channel is changed from an upward direction to a downward direction or from a downward direction to an upward direction to block some area of a lower portion thereof so as to prevent a refrigerant from being non-uniformly distributed while a flux is concentrated toward a rear side of the channel due to a fluid inertia in an area in which the flow path is changed, thereby delaying frosting upon heating.

  • Patent number: 10520256
    Abstract: A heat exchanger includes a plurality of principal heat exchange sections and auxiliary heat exchange sections. Each of the auxiliary heat exchange sections is in series connection to a corresponding one of the principal heat exchange sections. Tube number ratios of the principal heat exchange sections are obtained by dividing the number of the flat tubes constituting each of the principal heat exchange sections to by the number of the flat tubes constituting a corresponding one of the auxiliary heat exchange sections. Of the principal heat exchange sections, the first principal heat exchange section, which is the lowermost one, has the smallest tube number ratio. Consequently, discharge of liquid refrigerant from a lower portion of the first principal heat exchange section is accelerated during defrosting, thereby shortening the time required for defrosting.

  • Patent number: 10473401
    Abstract: Problem to be Solved To provide a heat exchanger that can increase the performance by setting an optimal number of tube groups in a configuration where each of the tube groups is provided with headers. Solution The number of arrays of tube groups of a core section 2 is set to three rows. The number N of heating medium flow holes 21 per tube is set for each width dimension Tw of tubes 20, and the tubes 20 are formed such that the width dimension Tw of the tubes and a flow channel cross-sectional area S satisfy a relationship of S1?S?S2. Therefore, the number of arrays of the tube groups in the core section 2 can be set to an optimal number of arrays for improving the endothermic capacity and reducing the weight, and sufficient refrigerant flow rate and pressure resistance can be secured. As a result, even when there is a restriction on the size of the entire heat exchanger, a light high-performance heat exchanger can be configured.

  • Patent number: 10465955
    Abstract: A heat exchanger includes a plurality of flat tubes, a header part, and a guide part. An interior of the header part is partitioned into first and second spaces. One end of each of the tubes is connected to the first space. The guide part has a guide space positioned below the first space. The guide space communicates with the first space via an ascending opening. The first and second spaces communicate with each other via upper and lower communication ports provided within upper and lower sides of the header part, respectively. When the heat exchanger is viewed from above after installation, the tubes and the ascending opening have an area of overlap, and the ascending opening and a space where the lower communication port is extended do not overlap or have an area of overlap that is up to 50% of the ascending opening.
