Embodiment 1

[0021] see figure 2 The temperature adjustment device provided by Embodiment 1 of the present invention includes: a power management unit 11 (Power Management Unit, PMU), an integrated circuit 12 (Integrated Circuit, IC), and a semiconductor refrigerator 13 (Thermo-electric-Cooler, TEC) integrated in the IC12. ) and the temperature detection module 14 connected with PMU11 and IC12 respectively, PMU11 is also connected with TEC13. in,

[0022] A temperature detection module 14, used to detect the internal temperature of the IC12;

[0023] The PMU11 is used to obtain the internal temperature of the IC12 through the temperature detection module 14. If the temperature is higher than the set threshold, the reverse current is output to the TEC, that is, the current through the TEC13 flows from TEC- to TEC+, so that the TEC13 starts to cause cold;

[0024] TEC13 is used to start cooling when the current passing through the TEC is a reverse current, that is, the current passing th...

Embodiment 2

[0031] see image 3 , the temperature adjustment method provided by Embodiment 2 of the present invention includes the following steps:

[0032] S101. The temperature detection module detects the internal temperature of the IC;

[0033] S102. The PMU obtains the internal temperature of the IC through the temperature detection module;

[0034] S103. If the temperature is higher than the set threshold, the PMU outputs a reverse current to the TEC to enable the TEC to start cooling, wherein the TEC is integrated inside the IC.

[0035] In Embodiment 2 of the present invention, the method may further include:

[0036] If the temperature detection module obtains that the internal temperature of the IC is lower than a set threshold, the PMU outputs a forward current to the TEC, causing the TEC to start heating.

[0037] In the second embodiment of the present invention, the temperature detection module is specifically a thermistor NTC.

[0038] In Embodiment 2 of the present inv...

Abstract

The invention is applicable to the electricity field, and provides a temperature adjusting device, a temperature adjusting method and a mobile terminal. The temperature adjusting device comprises a power management unit PMU, an integrated circuit IC, a semiconductor refrigerator TEC and a temperature detection module, wherein the TEC is integrated in the IC, the temperature detection module is respectively connected with the PMU and the IC, the PMU is further connected with the TEC, and the temperature detection module is used for detecting internal temperature of the IC; the PMU is used for acquiring the internal temperature of the IC through the temperature detection module, and outputs a reverse current to the TEC so that the TEC start refrigeration when the internal temperature is higher than a set threshold value; and the TEC is used for starting refrigeration when the current flowing through the TEC is a reverse current. The temperature adjusting device is small in size and light in weight, does not occupy extra space, can achieve the radiating purpose, ensures that the IC operates at reasonable temperature, and prolongs the service life of the IC, thereby prolonging the service life of the mobile terminal comprising the temperature adjusting device; the closed-loop temperature control can be achieved; and the temperature adjusting device has the advantages of having no motion device and no noise, and being high in operational reliability.

Description

technical field [0001] The invention belongs to the field of electricity, and in particular relates to a temperature regulating device, method and mobile terminal. Background technique [0002] At present, mobile terminals are becoming more and more popular, and are developing toward a direction of more intelligence, higher integration, and stronger functions. While bringing more convenience to users, the power consumption of mobile terminals is also gradually increasing. Especially for mobile terminals based on the third-generation mobile communication technology (3rd-generation, 3G) and long-term evolution (Long Term Evolution, LTE) system, the main frequency of the internal main chip is getting higher and higher, and the memory access speed is getting faster and faster. The power consumption of radio frequency power amplifier and power management is correspondingly higher and higher, therefore, the cooling treatment of mobile terminals is particularly important.
