The chipset 6 is an object to be protected, and the chipset 6 may be a processor of any device, and the present device may be used as long as there is a need for heat insulation and temperature reduction of a chip.
Further, the heat-absorbing medium 8 can absorb heat by evaporation, and plays a role in cooling the chipset 6, wherein the heat-absorbing medium flow control system is used for controlling the evaporation flow and supplement of the heat-absorbing medium 8 in the heat insulation layer, and the heat-absorbing medium 8 can absorb heat in the evaporation flow process. The heat insulation layer is a cavity, on one hand, plays a role in heat insulation and reduces external heat transfer to the cavity, and on the other hand, is used for accommodating the heat absorption medium 8. When the device is in a high-temperature environment, the heat insulation layer firstly plays a certain heat insulation role, and with the rise of temperature, the heat absorption medium flow control system controls the heat absorption medium 8 to evaporate and absorb heat after the preset temperature is reached, so that the rise of temperature is slowed down, and under the heat insulation and cooling effects, the whole device can work in a well with high temperature (above 175 ℃).
In the present embodiment, the heat-insulating cooling device further includes a storage tank 3 and a replenishing device, in which a heat-absorbing medium 8 is stored; the storage tank 3 is communicated with a containing cavity containing the heat-absorbing medium 8 and is used for containing the heat-absorbing medium 8 flowing out of the heat-insulating layer; the supplementing device is communicated with the accommodating cavity for accommodating the heat absorbing medium 8 and is used for conveying the heat absorbing medium 8 into the heat insulating layer. The storage tank 3 and the supplement device are arranged, so that the heat-absorbing medium 8 can be stored and reused, and the influence on the surrounding environment of the device is reduced.
Further, the heat absorbing medium flow control system includes a temperature control flow valve 5 and a pressure valve 11; the temperature control flow valve 5 is arranged on a channel between the storage tank 3 and the accommodating cavity and is used for controlling the evaporated heat-absorbing medium 8 to flow into the storage tank 3 according to a preset temperature; a pressure valve 11 is arranged on the passage between the replenishing device and the accommodating cavity and is used for controlling the heat absorbing medium 8 in the replenishing device to be conveyed into the insulating layer 7 according to preset pressure. The temperature control flow valve 5 can control the flow amount (from 0 to maximum) according to the temperature. By adopting the scheme, in actual work, when the preset temperature is reached, the temperature control flow valve 5 is opened, the heat absorbing medium 8 in the heat insulating layer evaporates and absorbs heat and flows into the storage tank 3, when the quantity of the heat absorbing medium 8 in the heat insulating layer is reduced, the internal pressure is reduced, the pressure difference between the heat absorbing medium and the supplementing device is increased, and when the pressure difference reaches the preset value, the pressure valve 11 is opened, and the heat absorbing medium 8 in the supplementing device flows into the heat insulating layer for supplementing. The way of controlling the evaporation flow and replenishment of the heat absorbing medium 8 in the thermal insulation layer is not limited to this, and those skilled in the art can design other ways of controlling the evaporation flow and replenishment according to the need.
In the present embodiment, the heat-insulating cooling device further includes a power generation group 1, and the temperature control flow valve 5 and the pressure valve 11 are both electrically connected to the power generation group 1. The power generation unit 1 supplies electric power to the temperature control flow valve 5 and the pressure valve 11. The chip set 6 is also electrically connected with the power generation set 1 to obtain electric energy. The power of the chip set 6, the temperature control flow valve 5 and the pressure valve 11 may be the power generation set 1, or may be an external power supply, and those skilled in the art can ensure that the components which need the power in the use state can obtain the power.
Further, a coolant 2 is provided in the storage tank 3, and the coolant 2 is used to cool the heat-absorbing medium 8 evaporated into the storage tank 3.

The most common phase change material is water, which changes from liquid to gas when reaching a given temperature (which varies with ambient pressure, usually around 100 ℃), and absorbs heat during this process, but the temperature of the water does not change. The heat absorption principle of the phase-change material in the embodiment is similar to that of water, the phase-change material absorbs heat in the process of changing from liquid to gas, but the temperature of the phase-change material does not change, and the absorbed heat mainly comes from the chipset 6, so that the effect of cooling the chipset 6 can be achieved.

A vacuum gap may be provided between the first and second insulating layers 9, 10 to further reduce the heat transfer efficiency and thereby slow down the rapid rise in internal temperature. The first heat insulation layer 9 and the second heat insulation layer 10 are both heat insulation materials.
The embodiment also provides a measurement while drilling device which comprises the chipset 6 and adopts the heat insulation cooling device provided by the embodiment to heat-insulate and cool the chipset 6. Of course, for those skilled in the art, the heat-insulating cooling device provided in this embodiment may also be applied to other devices requiring heat insulation and cooling, so as to perform heat insulation and cooling on the corresponding chipset.
