  • Patent number: 10914527
    Abstract: A tube bundle heat exchanger has tubes which are held at each side in tube plates or oval-tube collecting-tube plates and are connected to these in each case by means of a weld seam. The connection of the tubes to the inlet-side tube plate or oval-tube collecting-tube plate is formed in each case by means of a conical and/or trumpet-shaped transition piece. The cross section of the transition piece reduces as viewed in the gas flow direction in such a way that the inlet-side end, as viewed in the gas flow direction, of the transition piece is connected in a buttjoint to the tube plate or oval-tube collecting-tube plate. The inner and outer contours of the transition piece and of the welded connection region are formed without gaps and comers to the tube plate or oval tube collecting-tube plate and so as to be straight and/or with a radius, measured from the outer contour, of at least 5 mm.

  • Patent number: 10890382
    Abstract: A heat dissipation device includes two titanium metal sheets, which are subjected to a heat treatment before undergoing mechanical processing, plastic working and surface modification. With these arrangements, the titanium metal sheets can be freely plastically deformed and possess a capillary force, and can therefore be used in place of the conventional copper material to serve as a material for making heat dissipation devices, and the heat dissipation devices so produced can have largely reduced weight and largely improved heat dissipation performance.

  • Patent number: 10864802
    Abstract: A flow channel located downstream of a temperature regulating device branches off into a first flow channel and a second flow channel. In the first flow channel, a windshield's-side flow channel connecting to a windshield's-side air outlet port and an adsorbent's-side flow channel connecting to an adsorbent inflow section are formed. At the time of regeneration treatment of an adsorbent, by interrupting communication between the first flow channel and the second flow channel, interrupting communication between a temperature regulating device outflow section and the windshield's-side air outlet port, and making the temperature regulating device outflow section and the adsorbent inflow section communicate with each other, the air warmed by the temperature regulating device is preferentially guided to the adsorbent.
