    • The invention relates to designing cases for hearing apparatuses more cost-effectively and ensuring an improved degree of hygiene. A box has an outer shell made out of a first plastic and an interior lining made out of a second plastic that is softer than the first plastic. The interior lining is attached to the inner wall of the outer shell. The interior lining is injected onto the outer shell. One or a number of hold-down devices formed in one piece with the interior lining protrude into the internal space of the interior lining in order to hold the hearing apparatus there. A jointless compound forms with the outer shell so that the soft interior lining is injected onto the hard outer shell. Water is thus unable to permeate into possible joints during cleaning and the case can be cleaned in a dishwasher for instance in respect of improved hygiene.
    • 本发明涉及更具成本效益地设计听觉设备的案例,并确保提高卫生程度。 盒子具有由第一塑料制成的外壳和由比第一塑料软的第二塑料制成的内衬。 内衬附着在外壳的内壁上。 将内衬注射到外壳上。 与内衬一体形成的一个或多个压紧装置突出到内衬的内部空间中,以将听力装置保持在那里。 与外壳形成无接缝化合物,使得软内衬被注射到硬外壳上。 因此,在清洁期间,水不能渗透到可能的接头中,并且例如可以在洗碗机中清洁外壳,例如在改进卫生方面。

    • A plate heat exchanger comprising a plurality of plates (12,13) which are stacked against each other and which are of a first and second type in order to form flow channels for a first and second medium. The plates form a heat exchanger block (2) with an upper side and a lower side and with two opposite side surfaces (10) and front faces (9). The first flow channels are peripherally sealed for the first medium and are fluidically connected to distributor and collector channels which are arranged in a vertical position with respect to the plate plane and which lead into inlet and outlet connection pieces (6,7) which are respectively arranged on the upper side and/or lower side (3,11). The second flow channels are open at the front surfaces (9) thereof and are sealed at the side surfaces (10) thereof. The open sides (9) form an inlet and outlet plane for the second medium.
    • 一种板式热交换器,包括彼此堆叠并且是第一和第二类型的多个板(12,13),以形成用于第一和第二介质的流动通道。 板形成具有上侧和下侧以及两个相对的侧表面(10)和前表面(9)的热交换器块(2)。 第一流动通道对于第一介质进行外围密封,并且流体连接到分配器和收集器通道,分配器和收集器通道相对于板平面布置在垂直位置,并且分别引入入口和出口连接件(6,7) 布置在上侧和/或下侧(3,11)上。 第二流动通道在其前表面(9)处敞开,并在其侧表面(10)处密封。 开口侧(9)形成用于第二介质的入口和出口平面。
