Liquid constant temperature bath used as heat source

Abstract

A liquid thermostatic bath which can also be used as a heat source is characterized in that: the liquid thermostatic bath is divided into a work area and a temperature regulation area, the middle is separated by a metal partition plate with a hole; the interior of the temperature regulation area is provided with an auxiliary heater and a main heater; a diversion barrel is arranged in the work area, the diversion barrel can be welded with a support to be fixed on the metal partition plate with the hole; a stirrer is provided with stirring paddles in both the temperature regulation area and the work area, stirring on the horizontal direction is implemented in the temperature regulation area, stirring on the vertical direction is implemented in the work area, the liquid thereof forms a great annular flow on the vertical direction between the metal partition plate with the hole and the top part of the thermostatic bath; the side wall of the work area is provided with a hole and is welded with a liquid circulating pipeline and a thermostatic liquid output pipeline, the liquid circulating pipeline is connected with a pipeline pump in series and then is connected with a liquid injection pipeline, the liquid injection pipeline extends into the temperature regulation area; the thermostatic liquid output pipeline is further connected with a liquid extraction pump, the liquid extraction pump extracts the thermostatic liquid by the thermostatic liquid output pipeline for external usage, and then the liquid is returned to the liquid injection pipeline after using.

Description

(1) Technical field: [0001] The invention relates to a liquid constant temperature bath which can also be used as a heat source, in particular to a constant temperature bath which can not only perform sensor temperature calibration, but also can be used as a heat source to precisely control the temperature of external objects. Belongs to liquid constant temperature tank. (2) Background technology: [0002] In the analysis of fluid thermophysical properties, it is sometimes necessary to continuously supply a large flow of constant temperature liquid, and the liquid can be refluxed after use. This requires a constant temperature bath with high power, high precision and strong anti-interference ability. The front-stage thermostat of the multi-stage precision temperature control thermostat also needs a thermostat that supplies a large flow of thermostatic liquid. [0003] At present, the liquid constant temperature baths produced and used in foreign countries and our country such as ...

AI Technical Summary

Problems solved by technology

[0006] 1. The bottom of the working area enters the liquid, and the upper end exits the liquid. In principle, there is a temperature difference in the vertical direction;

[0007] 2. There is no stirring in the horizontal direction, so the uniformity of the temperature field in the horizontal direction needs to be improved;

[0008] 3. The speed distribution in the working area is uneven, which is not conducive to the formation of a uniform temperature field;

[0012] 1. Both the cold and heat source and the working area are in the same tank, and the source is seriously affected, resulting in uneven temperature;

[0013] 2. The stirring in the working area is weak, and there is no division of vertical stirring and horizontal stirring;

[0014] 3. The heated liquid is directly mixed with the liquid in the working area, resulting in uneven temperature field;

[0015] 4. After the cold source enters the main constant temperature tank, although the heat is exchanged through the heat exchange bottom plate, there is no further mixing and stirring measures
