Definitions
- the present invention relates to a heating apparatus, particularly to a heating apparatus for heating liquid.
- a heating resistor is encapsulated with an insulator and then embedded in cast aluminum having higher thermal conductivity, and a stainless tube is curved to form a continuous liquid passageway and embedded in the cast aluminum.
- Heat generated by the heating resistor cannot directly enter the liquid inside the stainless tube but heats the cast aluminum to a given temperature beforehand. Then, heat exchange undertakes between the cast aluminum and the liquid through the stainless tube. Because aluminum has a higher thermal inertia, the following problems may take place: 1. A longer period of time (about 15-305 seconds) is spent in preheating the cast aluminum to the required temperature while starting up the device. 2. If the rate that the heating resistor generates heat is lower than the rate that the liquid absorbs heat in the case requiring continuous liquid supply, the temperature of the cast aluminum is decreased; if the temperature of the output liquid is not allowed to be lowered, more time would be spent in preheating. 3.
- the heating device using cast aluminum with high thermal inertia needs preheating to supply liquid of a constant temperature; if the heating device is required to supply liquid continuously, the temperature of the output liquid is hard to keep constant; further, because of high thermal inertia of cast aluminum, it is unlikely to realize continuous variation of liquid temperature; besides, cast aluminum is heavy and bulky, and the fabrication technology is very complicated.
- a plastic runner is arranged inside a thick-film stainless tube to avoid the influence of thermal inertia.
- Plastic material has a given hardness.
- the outer diameter of the plastic runner must be reduced and is not fully fit to the inner diameter of the stainless outer tube.
- sealing between the plastic and metal can only be realized by sealing rings, it is unlikely to achieve the requirement of keeping a pressure of 8-10 Bar. Even at ambient pressure, the sealing rings, which are deteriorated by long-term usage at high temperature, may lead to liquid leakage.
- the traditional water purification machine normally has only a filtration section and a temperature modification section. In usage, water is filtered, next chilled or heated, and then supplied to users.
- the traditional water purification machine still has the following problems: the input water has different temperatures in different environments, and thus the output water also has different temperatures; for example, even though water is heated/chilled for an identical period of time, the output water has different temperatures in winter and summer because the input water has different temperatures in winter and summer. Therefore, some water purification machines have a function of adjusting the time of heating or chilling water to solve the problems of different input water temperatures.
- the measure can satisfy the users in the output water temperature, it also brings about some inconveniences.
