(First embodiment)
Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a plan view of the suction module 2A according to the first embodiment of the present invention without a cover 5A, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 3 is a schematic enlarged view of a portion III in FIG. 2, FIG. 4 is an enlarged view of a portion IV in FIG. 2, and FIG. 5 is a drawing of the adsorption module 2A with the lid 5A assembled in FIG. It is sectional drawing in the II-II cross section.

  The adsorption module 2A according to the present embodiment utilizes the fact that an adsorbent 42 described later adsorbs a vapor-phase adsorbed medium, evaporates the adsorbed adsorbed medium, and exhibits the refrigerating capacity by the latent heat of vaporization. Is. Therefore, for example, an adsorption heat exchanger, which will be described later, is configured by an adsorption module and used in an adsorption refrigeration apparatus, and is suitable for application to an air conditioner for a vehicle.

  In this embodiment, water vapor is used as the adsorbed medium. Hereinafter, the adsorbed medium is referred to as water vapor, but is not limited to water vapor. The adsorption module 2A (2) includes a metal container 3A (3), an adsorbent packed layer 4A (4) that is pressurized and filled in the container 3A, and an adsorption filled in the container 3A. And a metal lid 5A (5) covering the agent filling layer 4A.

  The container 3A of the present embodiment has a quadrangular shape in which a thin depression is formed by press molding a copper plate, and the outer surface of the container 3A is a heat transfer surface. The outer shape of the container 3A (that is, the adsorption module 2A) is not limited to a square. In addition, the heat transfer surface is not necessarily a flat surface, and may be, for example, a wavy uneven surface, or may have a slight inclination.

  A predetermined amount of mixed powder (sintered powder) in which the metal powder 41b and the adsorbent 42 are mixed is filled in the recess of the container 3A, and the upper part is heated with a pressure jig (not shown) (the heat transfer surface of the container 3A). To the adsorbent packed layer 4A before sintering. This pressurization increases the number of contact points between the metal powders 41b and the contact points between the inner surface of the container 3A and the metal powder 41b.

  A grid-like convex portion is formed on the pressing surface of the pressurizing jig, and the convex portion is transferred to the surface of the adsorbent-filled layer 4A formed by pressurization. As shown in FIG. On the surface of the packed bed 4A, lattice-shaped water vapor flow grooves (adsorbed medium flow grooves) 43 are formed. The adsorbed medium flow grooves 43 are not limited to the lattice arrangement, and may be a radial arrangement from the center of the adsorbent packed layer 4A toward the peripheral portion.

  Further, as shown in FIG. 4, the steam circulation groove 43 is provided with a draft so that the pressurizing jig can be easily detached. The water vapor flow groove 43 communicates with a water vapor flow port (adsorbed medium flow port) 21 opened in the lid 5A described below. Then, the water vapor supplied from the water vapor circulation port 21 passes through the water vapor circulation groove 43 and is quickly supplied to and penetrates the entire adsorbent packed bed 4A, and the adsorbent 42 is adsorbed. In addition, when the heat transfer surface is heated by a heat exchange medium (for example, hot water), the adsorbent 42 desorbs the adsorbed water vapor, and the desorbed water vapor passes through the water vapor circulation groove 43 quickly. It will be collected at the distribution port 21.

  As shown in FIG. 5, the lid 5 </ b> A has a quadrangular shape formed by press-molding a copper plate and projecting outwardly a water vapor circulation port 21 through which water vapor flows. The lid 5A is overlaid on the container 3A after the adsorbent-filled layer 4A is formed under pressure.

  Although the adsorbent 42 itself is in contact with the metal powder 41b and the container 3A and is not sintered, the adsorbent 42 is held by the porous sintered fins 41 formed by sintering the metal powder 41b. For this reason, the adsorbent 42 can be fixed without being scattered even if the flow of water vapor during adsorption / desorption or the flow of air due to evacuation in the mixed powder occurs.

For this reason, the number of contact points between the metal powders 41b and the number of contact points between the inner surface of the container 3A and the metal powder 41b are surely increased, and the bondability between the container 3A and the metal powder 41b is improved. The thermal resistance at the interface with the powder 41b can be reduced. A part of the pressure surface of the adsorbent packed layer 4A is in contact with the inner surface of the lid 5A. According to this, when the adsorption module is operated, the inside of the container 3A is substantially evacuated, and pressure is applied to the container 3A from the outside, but the adsorbent filling layer 4A itself becomes a pressure-resistant structure. Can also withstand external pressure. Further, the heat transfer area with the adsorbent packed bed 4A can be increased.
