恒温箱在医学方面的用途很广,但又常失灵,故有必要对恒温箱的构造原理、保养、修理等,作一说明,供大家参考。恒温箱的构造与原理常见的电力恒温箱有热空气式、隔水式及恒温水浴等。热空气式是以电热丝直接使箱内空气加温;隔水式是箱的四周除了门的一面外都是夹層的水槽,以电热丝热水槽中的水以保持箱内的温度;恒温水浴是以电热丝热水槽中的水以保持温度。恒温箱的种类及型式虽多,但其主要部分不外乎保温、加热及温度控制三部分。保温部分亦就是温箱的外壳,保温層的好坏,对耗电量的关系很大。保温好,耗电量就少。常用的保温材料有软木板,甘蔗板,刨花板及木板等。温度较高的用石棉板,石棉粉或玻璃绒等。一般温箱门部的保温程度没有其他各面好。加热部分除了一部分孵箱及初生婴儿保温箱
Thermostat in the medical use is very wide, but often fails, it is necessary on the thermostat structure principle, maintenance, repair, etc., for a description for your reference. The structure and principle of incubators Common electric incubators are hot air, water and constant temperature water bath. Hot air type is the heating wire directly to the air inside the box; water is the box around the door in addition to the sandwich side of the water tank to the electric wire hot water tank to maintain the water tank temperature; constant temperature Water bath is based on electric wire hot water tank to maintain the temperature of water. There are many types and types of incubators, but the main part is nothing more than heat preservation, heating and temperature control of three parts. Insulation part is also the temperature box shell, insulation is good or bad, a great relationship between power consumption. Good insulation, less power consumption. Commonly used insulation materials are cork board, sugarcane board, particleboard and wood. Temperatures with asbestos board, asbestos powder or glass wool and so on. General thermostat door insulation level no other good. In addition to heating part of the incubator and newborn incubator
