    • A thermostat (1) includes a plate body (2), a heat insulator (3), and an electric heater (5). The plate body (2) defines a cavity (8) therewithin. The plate body (2) has on its bottom two openings (11) and (12), which communicate with the cavity (8) and function as a cooling medium inlet and a cooling medium outlet, respectively. The outer periphery of the plate body (2) is covered with the heat insulator (3). That prevents heat intrusion and/or dissipation from the outer periphery of the plate body (2) in transferring heat between the mounting face (7) and a heat transfer medium within the cavity (8). That reduces the thermal influence on the mounting face (7), thereby ensuring more uniform temperature distribution on the mounting face (7).
    • 恒温器(1)包括板体(2),绝热体(3)和电加热器(5)。 板体(2)在其中限定了空腔(8)。 板体(2)在其底部具有分别与空腔(8)连通并用作冷却介质入口和冷却介质出口的两个开口(11)和(12)。 板体(2)的外周被绝热体(3)覆盖。 这防止了在安装面(7)和空腔(8)内的传热介质之间传递热量的板体(2)的外周的热侵入和/或耗散。 这降低了对安装面(7)的热影响,从而确保安装面(7)上的更均匀的温度分布。
