Embodiment

[0019] Such as image 3 , Figure 4 As shown, the dry and wet bulb thermometers of the present invention that prevent heat radiation from motors include a test box 1, and a centrifugal fan 5 is installed at the outlet of the test box 1, and the centrifugal fan 5 is connected to the outlet of the test box through an S-shaped elbow 7. The test box 1 is a dry and wet bulb thermometer test box.

[0020] The S-shaped elbow 7 is an S-shaped pipe formed by two 180-degree semicircular elbows.

[0021] The centrifugal fan 5 is not on the same axis as the outlet of the test box 1 .

[0022] figure 1 , figure 2 It is a dry and wet bulb thermometer of the prior art, and as can be seen by comparing with the present invention, we have changed the way that the previous centrifugal fan 5 is directly connected to the outlet of the test box 1, but the outlet of the test box 1 passes through a S Shape elbow 7, then communicate with centrifugal blower 5 again. The structure of the S-shaped...

Abstract

The invention discloses a dry bulb thermometer and a wet bulb thermometer capable of preventing the heat radiation of a motor, comprising a test box. The outlet of the test box is provided with a centrifugal blower which is connected with the outlet of the test box through an S-shaped elbow; the S-shaped elbow is an S-shaped pipeline comprising two semicircular elbows at 180 degrees, and the centrifugal blower and the outlet of the test box are not on the same axis. The S-shaped elbow structure provided by the invention can prevent the heat radiation of the motor from directly radiating the dry bulb thermometer and the wet bulb thermometer; meanwhile, the influence of the heat radiation of the motor can be effectively lessened by the diffuse reflection and the absorption action of the S-shaped elbow on the heat radiation so that the heat radiation of the motor can not be directly radiated on the dry bulb thermometer and the wet bulb thermometer, and the aim of lowering the temperaturemeasuring errors of the dry bulb thermometer and the wet bulb thermometer is achieved.

Description

technical field [0001] The invention relates to the field of air conditioner development and temperature and humidity testing, in particular to a dry and wet bulb thermometer for preventing heat radiation from a motor. Background technique [0002] During the development and testing of energy-saving air conditioners, it is necessary to measure the enthalpy value of the air, and the measurement of the enthalpy value is determined by measuring the dry and wet bulb temperature of the air with a dry and wet bulb thermometer. [0003] The traditional dry and wet bulb thermometers we use use a centrifugal fan to draw air so that the wind speed flowing through the wet bulb thermometer meets the requirements for measuring the wet bulb temperature (generally, the wind speed blowing through the wet bulb gauze cover on the wet bulb water cup must reach a certain level. requirements). The traditional arrangement of dry and wet bulb thermometers is to connect the centrifugal fan directl...
