The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0046] The following describes the functional evaluation method and device of the cooling wearable device of the embodiment of the present application with reference to the accompanying drawings. In view of the related technologies mentioned in the background technology center, the functional evaluation method of the cooling wearable device cannot comprehensively evaluate the cooling effect and cooling duration of the clothing, resulting in the problem that inferior cooling wearable device products are widely circulated on the market. The present application provides a functional evaluation method of the cooling wearable device, in which the baseline test and cooling test data of the cooling wearable device can be collected in a certain environment, and its performance can be accurately obtained. Based on this data, the effective cooling power and duration are obtained, which intuitively reflects the cooling capacity and duration of the device, thereby calculating the heat dissipation cooling rate and efficiency, which can efficiently reflect the cooling speed of the cooling clothing and the effective utilization rate of the phase change cooling material, so that the functional evaluation of the cooling clothing is more comprehensive, comprehensive and effective, and provides a scientific basis for the research and development, improvement and selection of cooling wearable devices. This solves the problem in related technologies that the functional evaluation method for cooling wearable devices is unable to comprehensively evaluate the cooling effect, cooling duration and other functional advantages and disadvantages of clothing, resulting in the widespread circulation of inferior cooling wearable device products in the market.

[0047] The cooling wearable device involved in the embodiment of the present application is a cooling garment, such as Figure 1 As shown, the cooling garment is a cold storage type cooling vest. In order to evaluate the functionality of the cooling garment, the embodiment of the present application adopts a warm manikin system, such as Figure 2 As shown, in this system, a simulated human body is placed in a temperature and humidity controllable environmental chamber to simulate the human body's response to cooling clothing in different states; environmental sensors are used to detect environmental parameters such as temperature and humidity in the environmental chamber; thermal control software can start and control the operation of the warm-body manikin, set test parameters, and process and analyze the data recorded by the manikin to calculate the functionality of the cooling clothing; a water pump can circulate liquid or regulate water flow in the system; a water storage device can store a certain amount of water or other liquids, which is related to certain functions of the cooling clothing, for example, it can be used to simulate human sweating or be used in conjunction with the water cooling system of the cooling clothing.

[0048] Specifically, Figure 3 A schematic flow chart of a functional evaluation method for a cooling wearable device provided in an embodiment of the present application.

[0049] like Figure 3 As shown, the functional evaluation method of the cooling wearable device includes the following steps:

[0050] In step S301, when the cooling wearable device is in a preset environment, baseline test data and cooling test data of the cooling wearable device in a baseline test and a cooling test are collected respectively.

[0051] It can be understood that placing the heated manikin standing in an environmental chamber with controlled temperature and humidity, and testing with the cooling function of the cooling clothing turned off is a baseline test, and testing with the cooling function of the cooling clothing turned on is a cooling test.

[0052] Before the test begins, the temperature in the environmental chamber must reach a stable state, that is, the temperature no longer changes or changes very little. After the temperature of the environmental chamber stabilizes, turn on the thermal manikin and start recording the epidermal temperature and heating power of various parts of the thermal manikin. Each test lasts at least 2 hours. The baseline test data and cooling test data recorded by the thermal manikin will be used for subsequent functional calculations of the cooling clothing.

[0053] The embodiment of the present application can place a heated manikin in an environmental chamber with controllable temperature and humidity for testing, accurately control the test conditions, reduce the interference of external factors on the test results, improve the accuracy of the test, perform baseline tests and cooling tests under certain environments, and accurately obtain relevant data of the cooling wearable device, providing a reliable data basis for subsequent functional calculations.

[0054] In step S302, based on the baseline test data and the cooling test data, the effective cooling power and effective cooling duration of the cooling wearable device are obtained, and the heat dissipation cooling rate and heat dissipation cooling efficiency of the cooling wearable device are calculated.

[0055] In some embodiments, the effective cooling power and effective cooling duration of the cooling wearable device are obtained, including: obtaining the effective cooling power according to the difference between the instantaneous cooling power of a sweating thermal manikin when the cooling wearable device is turned on or worn and a benchmark heat dissipation power, wherein the benchmark heat dissipation power is the heat dissipation power through the thermal manikin when the cooling clothing is turned off or not worn, the instantaneous cooling power is the instantaneous heat dissipation power through the thermal manikin when the cooling clothing is turned on or worn, and the effective cooling power is the difference between the instantaneous cooling power and the benchmark heat dissipation power.

[0056] In one embodiment of the present application, the calculation formula for the effective cooling power is:

[0057]

[0058] Where P is the effective cooling power, t c is the cooling time, H i,c is the instantaneous heat dissipation of the ith section of the manikin when the manikin is wearing cooling clothing or turning on the cooling clothing, H i,b is the reference heat dissipation of the ith section of the thermal manikin, S i is the surface area of ​​the i-th section of the thermal manikin, and n is the number of sections of the thermal manikin for calculating the heat dissipation and cooling rate.

[0059] In other embodiments, the net heat dissipation cooling power of the cooling wearable device is obtained according to the effective cooling power and the reference cooling power to obtain the effective cooling time. The time required when the net heat dissipation power is as low as 50W is the effective cooling time. In some cases, during the test, before the net heat dissipation cooling power is reduced to 50W, the time from the start of the test to the power dropping to 50W is recorded, which is the effective cooling time; in other cases, during the maximum test period of 2 hours, the net heat dissipation cooling power is always greater than 50W, and the effective cooling time is defined as more than 2 hours.

[0060] Optionally, in one embodiment of the present application, the heat dissipation and cooling rate and the heat dissipation and cooling efficiency of the cooling wearable device are calculated, including: obtaining the baseline test temperature rise gradient and the cooling test temperature rise gradient of the cooling wearable device; calculating the heat dissipation and cooling rate according to the baseline test temperature rise gradient and the cooling test temperature rise gradient.

[0061] In the actual implementation process, the heat dissipation and cooling rate test uses a constant power of a warm body manikin to simulate a certain degree of human metabolic rate. When the manikin's skin temperature exceeds 38°C, the experiment is terminated. When the manikin's constant power is used to simulate a certain degree of human metabolic rate, the heat dissipation and cooling rate is the difference between the baseline test temperature rise gradient and the cooling test temperature rise gradient. The formula is:

[0062]

[0063] Among them, T i is the heat dissipation and cooling rate of the dummy in the i-th section, T i,b is the instantaneous skin temperature rise rate of the dummy part i when the cooling clothing is closed or not worn (i.e., the benchmark test temperature rise gradient, T i,c is the instantaneous skin temperature rise rate of the dummy part i when the cooling clothing is turned on or worn, T i,c -T i,b is the instantaneous effective cooling rate.

[0064] Optionally, in one embodiment of the present application, the calculation formula for heat dissipation and cooling efficiency is:

[0065]

[0066] Among them, E is the heat dissipation and cooling efficiency, Q m is the total enthalpy of a certain mass of phase change material, S is the surface area of ​​the dummy, t c is the cooling time, H i,c is the instantaneous heat dissipation of the ith section of the manikin when the manikin is wearing cooling clothing or turning on the cooling clothing, H i,b is the reference heat dissipation of the ith section of the thermal manikin, S i is the surface area of ​​the i-th section of the thermal manikin, and n is the number of sections of the thermal manikin for calculating the heat dissipation and cooling rate.

[0067] According to the principles of thermodynamics, the latent heat of phase change can be calculated by the following formula:

[0068] Q=m·ΔH

[0069] Among them, Q is the latent heat of phase change, m is the mass of the substance, and ΔH is the phase change enthalpy per unit mass of the substance (a constant related to the properties of the substance).

[0070] In some cases, for a substance changing from a solid to a liquid, the enthalpy of phase change can be expressed as:

[0071] ΔH=H melt

[0072] Among them, H melt The heat absorbed by a unit substance when it changes from solid to liquid, also known as the heat of fusion (the heat of fusion is a constant related to the properties of the substance).

[0073] The embodiments of the present application can accurately obtain key indicators such as effective cooling power, effective cooling time, heat dissipation cooling rate and heat dissipation efficiency of the cooling wearable device through detailed calculation formulas and clear parameter definitions, provide accurate data support for evaluating device performance, and the evaluation process is scientific and rigorous.

[0074] In step S303, a functional evaluation result of the cooling wearable device is generated according to the effective cooling power, the effective cooling time, the heat dissipation cooling rate and the heat dissipation cooling efficiency.

[0075] It can be understood that the embodiment of the present application, on the basis of proposing the functional indicators of cooling clothing, namely effective cooling power and effective cooling time, comprehensively considers the two indicators characterizing the functionality of cooling clothing, namely heat dissipation cooling rate and heat dissipation cooling efficiency, and generates corresponding evaluation results, which can efficiently reflect the cooling speed of the cooling clothing and the effective utilization rate of the phase change cooling material, making the functional evaluation of the cooling clothing more comprehensive, comprehensive and effective.

[0076] To better understand this method, the principle is described below. Figure 4 As shown, the principle of the functional evaluation method of the cooling wearable device in the embodiment of the present application is as follows:

[0077] Step S401: Testing the system of a thermal manikin.

[0078] The system may include a temperature and humidity controlled environment chamber in which the heated manikin is placed standing. The heated manikin may be equipped with various sensors for measuring parameters such as the epidermal temperature and heating power of various parts of the manikin.

[0079] Step S402: a method for calculating the functionality of cooling clothing.

[0080] Calculate indicators such as effective cooling power, effective cooling time, heat dissipation cooling rate and heat dissipation cooling efficiency.

[0081] Step S403: cooling clothing functionality evaluation results.

[0082] The results may include but are not limited to information such as sample serial number, effective cooling power, effective cooling time, heat dissipation cooling rate and heat dissipation cooling efficiency. Through these evaluation results, the performance of different cooling clothing can be compared and analyzed, providing a reference for the research and development, optimization and selection of cooling clothing.

[0083] To more specifically illustrate the application of this method, a specific embodiment will be described below. The embodiment is as follows:

[0084] (1) First, a heated manikin test was conducted to obtain the skin temperature and heating power data of 20 sections of the heated manikin for baseline and cooling tests. The baseline test data are shown in Table 1, and the cooling test data are shown in Table 2.

[0103] (2) The data output by the above-mentioned warm-body manikin is calculated using the functional calculation method of cooling clothing. The effective cooling power is 2.920W and the effective cooling time is 112min. The weight of the sample cooling clothing cold storage ice bag is 1224g, and the phase change enthalpy of the phase change material is 265.91kJ / kg. The total power consumption of the benchmark test manikin is 336803J, and the total power consumption of the cooling test manikin is 358315J. The difference is 21512J, and the heat dissipation and cooling efficiency is 6.61%. When calculating the heat dissipation and cooling rate Ti, a constant power of 65W / m2 of the warm-body manikin is used to simulate a certain degree of human metabolic rate. Taking Δt=1min, the maximum heat dissipation power is calculated to be 0.16℃ / min.

Based on this data, the effective cooling power and duration can be obtained, which can intuitively reflect the cooling capacity and duration of the device, thereby calculating the heat dissipation and cooling rate and efficiency.
