Description
Technical field
The present invention relates to a kind of temprature control method, in particular to multiple solid metallic materials or canister are protected simultaneously
The method for holding different temperatures.
Background technique
The control method of temperature is particularly important in the processing, heat treatment and its performance study of metal material, while food
Industry etc. is to the attention of processing temperature so that liquid thermostatic bath, thermostatic tank etc. are increasingly promoted in engineer application.
The method of control temperature can only keep the same temperature of metal or liquid at present.One of the most common method needs
The temperature of metal material or canister is realized by constant temperature oven.Distinguish if necessary to multiple metal materials or canister
Different temperature is kept just must individually to be operated to each article.Therefore operating process is many and diverse, and runing time is very long
With it is expensive.
The methods of liquid thermostatic bath and liquid immersion also belong to temprature control method single in this way.Base is used there are also some
The method that the realizations such as plate, fixture keep temperature inherently belongs to above-mentioned single temprature control method.And current method
The high-precision for realizing temperature is put forth effort in the control of more concern temperature, so that technical costs increases, and is extended and is reached balance
Time.Current method is difficult to realize simultaneity and needs multiple same equipment and operator if to realize by force,
It therefore is impossible in engineering reality.
Therefore, it can accomplish that the method for keeping different temperatures simultaneously for a kind of article can save a large amount of time and operation
Cost can also avoid many and diverse operating process.
Summary of the invention
It is an object of the invention to overcome the above-mentioned prior art insufficient, a kind of temprature control method is proposed.
The technical solution adopted by the present invention the following steps are included:
A kind of temprature control method, the method are specific as follows:
1) cold fluid and hot fluid continuously flow through partition both side surface respectively, and partition includes metal and insulation branch
Frame is embedded in the metal both ends inside heat insulated supporter and contacts respectively at cold fluid and hot fluid, and heat insulated supporter is completely isolated each
A metal；
2) cold fluid flows in the cold fluid pass close to partition one side, and hot fluid is close to partition another side
It is flowed in zone of heat liberation, cold fluid and hot fluid carry out heat convection in flow process, and heat is passed by metal from hot fluid
It is delivered to cold fluid；
3) meeting after operation 45-60 minutes under conditions of cold fluid and hot fluid inlet temperature and constant flow
Reach heat exchange equilibrium state, that is, reach each metal temperature is constant and the temperature of each metal is all different.
The metal is solid metallic materials or canister, and the canister can store other substances.
The partition, cold fluid pass and zone of heat liberation can be several.
The temprature control method can be realized with the pipe of isolation cold fluid and hot fluid.
The cold fluid pass and zone of heat liberation is not variable cross-section or variable cross-section straight channel or bending channel.
Compared with the prior art, advantages of the present invention is embodied in:
The present invention discloses a kind of temprature control method, can be realized multiple metal materials or canister while keeping different
Temperature.Current temperature maintenance methods are generally single temperature controlled methods, realize that effect of the invention must be to metal
Material or canister are operated one by one, therefore operating process is many and diverse, and runing time is very long and expensive.Of the invention
The advantages of temprature control method saves a large amount of time when completing above-mentioned function and reduces operating cost is obvious.And
And for analysis ware different temperatures bring changing rule, temprature control method of the present invention is in addition to temperature
Other conditions are all the same and do not have time difference and misoperation bring error, therefore have real-time and more acurrate analyte
The advantages of product temperature characterisitic.
