Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Shown in Fig. 1 and Fig. 2, according to embodiments of the invention, closed enclosure heat abstractor comprises jet pipe 2 and airtight box body 1, and box body 1 offers import 3 and outlet 4, jet pipe 2 stretches in box body 1 from import 3.
Closed enclosure heat abstractor forms confined space by airtight box body 1, then from import 3, heat transferring medium is introduced in box body 1 by jet pipe 2, make to need heat exchange structure to carry out abundant heat exchange in box body 1, then from outlet 4, heat transferring medium is discharged in box body 1, the seal of the mobility and box body 1 that can make full use of heat transferring medium carrys out heat exchanging structure and carries out heat exchange in box body 1, and heat transferring medium can be made directly and between heat exchange structure to carry out heat exchange, the heat exchanger effectiveness of heat exchange structure can be improved, thus good heat dispersion is provided.
Import 3 is arranged on the relative both sides of box body 1 with outlet 4, and outlet 4 is positioned at the upper position of box body 1.Because heat transferring medium can be vaporized afterwards at least partly in heat absorption, proportion is less, the top of box body 1 inner space can be in, outlet 4 is arranged on the top of box body 1, the heat transferring medium being more convenient to vaporize flows out from the outlet 4 of box body 1, the mobility of heat transferring medium in box body 1 can be improved, the heat transferring medium in raising box body 1 and the heat exchanger effectiveness between heat exchange structure.
Jet pipe 2 is provided with along its length multiple nozzle 5 towards the same side, heat transferring medium can carry out heat exchange from many places heat exchanging structure by nozzle 5 simultaneously, the distribution of heat transferring medium in box body 1 can be made more even, and the heat exchange between heat exchange structure is more abundant, can also ensure in box body 1, to arrive heat exchange structure heat exchange medium temperature everywhere even, improve the heat dispersion of closed enclosure heat abstractor.
Preferably, each nozzle 5 successively decreases along the cross section, direction away from jet pipe 2, thus can carry out throttling to the heat transferring medium sprayed from nozzle 5, reduces the temperature of the heat transferring medium entered in box body 1 further.The shape of nozzle 5 is such as conical.
Jet pipe 2 extends to side, outlet 4 place from the side, import 3 place of box body 1, because the length direction interval of multiple nozzle 5 along jet pipe 2 is arranged, therefore heat transferring medium can be made more fully to enter in box body 1 rapidly, the heat transferring medium in quickening box body 1 and the heat exchanger effectiveness between heat exchange structure.
Preferably, the endcapped of jet pipe 2, makes heat transferring medium cannot spray from the end of jet pipe 2, and can only spray from the nozzle 5 of jet pipe 2, can accelerate the flow velocity of heat transferring medium in box body 1 further, heat transferring medium is evenly distributed in box body 1 more.
In conjunction with shown in Figure 3, according to embodiments of the invention, steam compressing air conditioner comprises the compressor 6, condenser 7, electric expansion valve 8 and the evaporimeter 9 that connect successively, steam compressing air conditioner also comprises electrical appliance kit heat-radiating substrate and above-mentioned closed enclosure heat abstractor, the import 3 of closed enclosure heat abstractor is connected to the outlet 4 of condenser 7 from jet pipe 2, the outlet 4 of closed enclosure heat abstractor is connected to the import 3 of compressor 6, and electrical appliance kit heat-radiating substrate is arranged in the box body 1 of closed enclosure heat abstractor.
Low-pressure low-temperature gas-liquid mixed state refrigerant absorbs external heat and becomes low-pressure low-temperature gaseous coolant in evaporimeter 9, low-pressure gaseous refrigerant is compressed into pressure high temperature hot gas through compressor 6, high pressure-temperature gaseous coolant cools through condenser 7 afterwards, be condensed into high-pressure liquid refrigerant, a high-pressure liquid refrigerant part becomes low-pressure low-temperature gas-liquid two-phase state refrigerant after electric expansion valve 8 throttling, another part is low-pressure low-temperature gas-liquid two-phase state through magnetic valve 10 and nozzle 5 throttling, be sprayed onto on electrical appliance kit heat-radiating substrate, thus this part low-temp low-pressure gas-liquid two-phase state refrigerant absorbs heat evaporation in airtight box body 1, cooling electrical appliance kit heat-radiating substrate.The suction end that low-pressure gaseous refrigerant in box body 1 after heat absorption leads back compressor 6 through a refrigerant recovering pipe participates in circulation.
In the present embodiment, the physical dimension of box body 1 is that A × B × C is long × high × wide, it is long × wide that electrical appliance kit heat-radiating substrate is of a size of A × C, thus can, ensureing the overall structure basis that refrigerant and electrical appliance kit heat-radiating substrate fully contact reducing closed enclosure heat abstractor, make the structure of closed enclosure heat abstractor compacter.
The outlet 4 of jet pipe 2 is towards electrical appliance kit heat-radiating substrate, after refrigerant enters jet pipe 2 from condenser 7, directly can spray to electrical appliance kit heat-radiating substrate from outlet 4, the refrigerant being positioned at electrical appliance kit heat-radiating substrate surface is scattered, the new refrigerant supplemented arrives the surface of electrical appliance kit heat-radiating substrate, thus improves the heat exchanger effectiveness between refrigerant and electrical appliance kit heat-radiating substrate further.
Jet pipe 2 is arranged on the centre position of the side plate of side, electrical appliance kit heat-radiating substrate place, refrigerant can be made to arrive various loci in box body 1 quickly and evenly, improve the heat exchange uniformity of refrigerant.
Preferably, jet pipe 2 is provided with the magnetic valve 10 of adjustable jet pipe 2 openings of sizes, throttling can be carried out to the refrigerant entered in jet pipe 2 easily, and throttling size can be regulated.Magnetic valve 10 matches with nozzle 5, carries out throttling to the refrigerant entered in jet pipe 2, makes refrigerant throttling to be low-pressure low-temperature gas-liquid two-phase state better, thus can improve the heat exchanger effectiveness between refrigerant and electrical appliance kit heat-radiating substrate further.
Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
