Problems solved by technology

[0005] 2. In winter, when the car is parked outdoors at high latitudes overnight, without special measures, usually the main engine will not be able to run in the morning
[0006] Such a harsh fact makes the test of automotive electronic equipment even more severe. The temperature range it must withstand is almost the same as that used in aerospace or military applications, so that the optional spare parts for existing automotive electronic equipment are far less than those used in consumer electronics. Electronics, and they are expensive and lack sufficient temperature adaptability

Embodiment 1

[0037] according to figure 1 , figure 2 and image 3 , the present invention includes a heat-insulating warehouse body 1, an external heat-exchanging body 2 and a semiconductor refrigeration block 3, the heat-insulating chamber body 1 communicates with the external heat-exchanging body 2 and performs heat exchange, and the heat-insulating chamber body 1 and the external heat-exchanging body 2 A semiconductor refrigeration block 3 is arranged between them, and the semiconductor refrigeration block 3 performs correspondingly compensated heat exchange between the heat-insulating chamber body 1 and the external heat-exchanging body 2 to maintain a constant temperature of the heat-insulating chamber body 1 .

[0038] like figure 2 As shown, a temperature sensor 101 is arranged in the heat insulation bin body 1, such as Figure 7 As shown, a corresponding main control module 4 is set in the present invention, and the main control module 4 controls the on-off and connection pola...

Embodiment 2

[0053] according to Figure 8 and Figure 9 The difference between this embodiment and Embodiment 1 is that in this embodiment, the external heat exchange body 2 includes a third heat exchange block 21 and a fan 22, the third heat exchange block 21 is attached to the semiconductor refrigeration block 3, and the second The three heat exchange blocks 21 and the fan 22 are placed in a protective case 23, and the protective case 23 has openings at both ends.

[0054] The fan 22 helps to speed up temperature adjustment, and the protective shell 23 plays a role in protecting the third heat exchange block 21 and the fan 22, and the openings at both ends actually form an air duct, which further improves the practicability of the present invention.

[0055] As for other partial structures, principles, and methods that are the same or similar to those described in Embodiment 1, details will not be repeated here.

Embodiment 3

[0057] according to Figure 10 and Figure 11 , the difference between this embodiment and embodiment 2 lies in the following points:

[0058] 1) if Figure 11 As shown, in this embodiment, a pulse width modulation module 7 is also connected between the interface between the semiconductor refrigeration block 3 and the power supply 5 , and the main control module 4 sends a pulse width modulation signal to the pulse width modulation module 7 to adjust the current output.

[0059] 2) if Figure 10 As shown, in this embodiment, temperature sensors are provided at key parts of the heat insulation chamber body 1 and the external heat exchange body 2, and the specific settings are as follows:

[0060] In the heat insulation bin body 1: a temperature sensor 101 is set on the upper part of the inner bin 111; a temperature sensor 102 is set on the first heat exchange block 12; a temperature sensor 103 is set on the collective circuit 116 (the bottom of the first heat exchange block 1...

Abstract

A temperature-sensing device includes the heat insulation hollow. The heat insulation hollow is connected with the external heat exchanger between which is installed with the semiconductor refrigerating mass which keeps the temperature of the heat insulation hollow by compensating the heat between the hollow and the external heat exchanger. The heat insulation hollow includes the constant temperature hollow, the first heat-exchanging mass, the second heat-exchanging mass and the thermal pipe. The first heat-exchanging mass is installed in the hollow and the second is installed in the open part of the hollow, the outside of which is contacted with the refrigerating mass; the duct heater is connected between the first and second heat exchanging mass. The constant temperature hollow includes the inner barn, the out barn and the insulating material. The inner barn is set in the out barn and the insulating material is filled between the inner and the out barn, so the invention has improved the temperature adaptability of the electronic device in the vehicles.

Description

technical field [0001] The invention relates to control, in particular to a temperature control device. Background technique [0002] In various means of transportation, taking automobiles as an example, due to the huge power and energy required for air conditioning (whether cooling or heating), it is only possible to provide air conditioning services when the main engine is running normally. [0003] The obvious drawbacks of this regulation are as follows: [0004] 1. In summer, after turning off the engine, park the car in the sun and close the doors and windows. After dozens of minutes, the temperature inside the car will rise to an unbearable level for the human body. [0005] 2. In winter, when the car is parked outdoors at high latitudes overnight, without special measures, usually the main engine cannot be operated in the morning. [0006] Such a harsh fact makes the test of automotive electronic equipment even more severe. The temperature range it must withstand is...
