Background

The probe is generally used in an environment box with a light intensity test, and can be widely applied to the fields of photovoltaic industry, automobile industry, new material development and the like. The probe in the existing environment box is short in service life due to long-term exposure under strong light, and the acquired light intensity value is changed due to the change of the ambient temperature, so that the external mode of the probe is adopted, and the electric push rod is used for periodically acquiring light intensity data. However, the electric push rod is complex in processing and assembling process, high in precision requirement, high in cost and prone to failure after being frequently used. And the ambient temperature of the probe can not be in a constant temperature state, and the acquired light intensity value changes along with the change of the ambient temperature. The periodic data collection cannot feed back the actual light intensity value in real time.

Preferably, a temperature indicator is arranged in the heat-preservation and heat-insulation bin.

Compared with the prior art, the utility model discloses the beneficial effect that can reach is:

1. the service life is long: when the probe body is in a normal-temperature environment, the aging period of the internal material is long;

2. the precision is high: the light intensity value acquired by the probe is reduced along with the rise of the temperature of the probe, and when the temperature of the probe is kept in a normal-temperature environment, the accuracy of the detected light intensity value is high, and measurement deviation is not generated due to temperature rise;

3. the failure rate is low: the probe in the traditional mode uses an electric push rod, and a frequently used transmission device is easy to damage, and has the defects of air leakage and the like. The water-cooling probe has no transmission device and no movement mechanism, and the problem is stably and completely avoided.

4. The detection value is more accurate: the water-cooled probe can be placed in the test box, and the light intensity value is monitored in real time and the total light intensity value of the test sample is accumulated. Compared with the periodic monitoring analog calculation value of the probe in the traditional mode, the method is more accurate;

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the invention easy to understand, the invention is further explained below with reference to the specific embodiments, but the following embodiments are only the preferred embodiments of the invention, not all. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

The probe body 1 comprises a probe base and a probe head, and the probe head is arranged outside the heat-preservation and heat-insulation bin 3. The water cooling coil 2 is of a spiral tubular structure. The water cooling coil 2 is tightly attached to the probe base and is bonded by heat-conducting silica gel, so that the heat conductivity is increased. The water cooling coil 2 is connected with an external circulating water pump assembly, the external circulating water pump assembly comprises a water tank 5, a water pump 4 and a condenser 6, the water tank 5, the water pump 4 and the condenser 6 are sequentially connected, and the water inlet and the water outlet of the water cooling coil 2 are connected. The condenser 6 is an air-cooled condenser or a water-cooled condenser. Except the probe part which receives the light intensity, the rest parts of the probe body 1 and the water cooling coil 2 are arranged in the heat preservation and insulation bin 3, so that the radiant heat of lamplight and the heat convection of hot air in the box are effectively separated. When the probe part is positioned in the test box to collect the light intensity value, the heat is absorbed in a heat radiation and heat convection mode. The external circulating water pump assembly takes away the heat absorbed by the probe body 1 through the heat conduction mode with the water circulation in the water tank 5. The heat is finally taken away through the air-cooled condenser or the water-cooled condenser, the water temperature is ensured to be normal temperature for a long time, and when the heat absorbed by the probe body 1 and the heat taken away by circulating water reach a balance state, the effect of keeping the temperature of the probe part constant is achieved.
