[0059] In some embodiments, the temperature control table 331 and the electric energy meter 332 of the same constant temperature control unit 33 are arranged in a vertical direction on the case 1.

[0060] In this embodiment, the vertical direction interval arrangement means that the temperature control table 331 and the electric energy meter 332 are arranged in a vertical direction on the panel of the case 1 with a certain distance, which is convenient for operation and reading. The operator sets the temperature of the constant temperature test plate group 2 through the temperature control table 331; records the energy consumption of the constant temperature test plate group 2 through the electric energy meter 332; after the test is completed, the value of the electric energy meter 332 is read to calculate the thermal insulation performance of the fabric.

This size parameter makes the cabinet 1 more convenient to carry; the constant temperature test plate group 2 is connected to the cabinet 1 through the thin cable 13; the test is started, and the energy consumption data is recorded. The small and light cabinet 1 design facilitates carrying and on-site testing, improves the practicality of the instrument; and is suitable for testing in various environmental conditions, expanding the application range of the instrument.

[0063] In some embodiments, the number of constant temperature test plate groups is three, and the number of constant temperature control units 33 is three. Optionally, more than two constant temperature test plate groups which are completely the same are used, one group is used for measuring the fabric, and one group is used for detecting the environmental fluctuation to automatically compensate the influence of the environmental fluctuation. The three constant temperature test plate groups 2 are hung in the external environment; the temperature of the constant temperature test plate group 2 is set through the temperature control table 331; the energy consumption of the constant temperature test plate group 2 is recorded through the electric energy meter 332; after the test is completed, the value of the electric energy meter 332 is read, and the heat preservation performance of the fabric is calculated. The design of the three constant temperature test plate groups 2 can simultaneously perform multiple tests, and the test precision is improved through environmental fluctuation compensation; the design is suitable for fabric heat transfer performance testing in complex environmental conditions, expanding the application scenarios of the instrument.

[0064] Specifically, in use, one of the constant temperature test plate groups 2 is used to measure the energy loss E0 in the no-sample state, and the other two constant temperature test plate groups 2 are used to measure the energy loss E1 and E2 after covering the sample (i.e. the fabric sample 4 to be tested). The measurement result, i.e. the heat transfer effect, is expressed by the energy consumption ratio; for convenience of expression, the first fabric sample 4 to be tested is denoted as sample A, and the second fabric sample 4 to be tested is denoted as sample B; the energy consumption ratio of sample A is k1=E1 / E0, and the energy consumption ratio of sample B is k2=E2 / E0.

[0065] The principle that the tester shown in the embodiment can automatically compensate the influence of temperature disturbance of the test environment is that the space required for the test of the three constant temperature test plate groups 2 is not large, and relative to the disturbance of the ambient temperature and humidity and wind speed, it can be considered that the three constant temperature test plate groups 2 simultaneously suffer from the same disturbance, the energy losses E0, E1 and E2 simultaneously increase or decrease, but the influence on the ratios k1 and k2 is small, so according to the portable all-weather fabric heat transfer performance rapid tester shown in the embodiment, the environmental disturbance can be automatically compensated, and the requirement for the test environment is not high.

[0066] In some preferred embodiments, the test duration can be set by the timing module 12, the electric energy meter 332 continuously collects the electric energy consumed by the constant temperature test plate group 2 within the test duration after the test starts, and the electric energy meter 332 locks the value after the test ends, and the next test duration test can be quickly performed by pressing the test button 32, and the constant temperature test plate group 2 always maintains at the preset temperature during the whole process, and there is no need to wait for the temperature of the measured fabric sample 4 to be balanced again.

[0067] In the above technical solution, the power supply module 11 and the timing module 12 in the case 1, and the external test assembly and the control module 3 are used to realize the rapid test of the fabric heat transfer performance. During the test, the measured fabric sample 4 is single-layer covered and wrapped around the constant temperature test plate group 2, and is connected with the control module 3 through the thin cable 13. The constant temperature control unit 33 in the control module 3 corresponds to the constant temperature test plate group 2, and the temperature of the test plate is accurately controlled and the energy consumption is recorded through the temperature controller 331 and the electric energy meter 332. During the test, the constant temperature test plate group 2 maintains stable at the set temperature, and the electric energy meter 332 records the energy consumption, and finally the energy consumption ratio of the test plate group wrapped with the sample fabric and the bare test plate is compared, which directly reflects the heat transfer performance of the fabric. The technical solution has the advantages of simple structure, convenient operation, and can quickly and accurately test the heat transfer performance of the fabric. Through the accurate control and recording of the constant temperature control unit 33 and the electric energy meter 332, the accuracy and reliability of the test data are ensured. At the same time, the design that the test assembly and the case 1 are independent of each other makes the test process more flexible, and is suitable for test requirements under different environmental conditions. In addition, the portability of the tester makes it widely used in various occasions, and provides an efficient and reliable test means for the evaluation of the heat transfer performance of the fabric.
